For example, an HTML document always has a root <code id=optional-tags:the-html-element><a href=semantics.html#the-html-element>html</a></code> element, even if 722 the string <code><html></code> doesn't appear anywhere in the markup.</p> 723 724 725 <p>An <code id=optional-tags:the-html-element-2><a href=semantics.html#the-html-element>html</a></code> element's <a href=#syntax-start-tag id=optional-tags:syntax-start-tag-2>start tag</a> may be omitted 726 if the first thing inside the <code id=optional-tags:the-html-element-3><a href=semantics.html#the-html-element>html</a></code> element is not a <a href=#syntax-comments id=optional-tags:syntax-comments>comment</a>.</p> 727 728 <div class=example> 729 730 <p>For example, in the following case it's ok to remove the "<code><html></code>" 731 tag:</p> 732 733 <pre><!DOCTYPE HTML> 734 <strong><html></strong> 735 <head> 736 <title>Hello</title> 737 </head> 738 <body> 739 <p>Welcome to this example.</p> 740 </body> 741 </html></pre> 742 743 <p>Doing so would make the document look like this:</p> 744 745 <pre><!DOCTYPE HTML> 746 747 <head> 748 <title>Hello</title> 749 </head> 750 <body> 751 <p>Welcome to this example.</p> 752 </body> 753 </html></pre> 754 755 <p>This has the exact same DOM. In particular, note that white space around the root element is 756 ignored by the parser. The following example would also have the exact same DOM:</p> 757 758 <pre><!DOCTYPE HTML><head> 759 <title>Hello</title> 760 </head> 761 <body> 762 <p>Welcome to this example.</p> 763 </body> 764 </html></pre> 765 766 <p>However, in the following example, removing the start tag moves the comment to before the 767 <code id=optional-tags:the-html-element-4><a href=semantics.html#the-html-element>html</a></code> element:</p> 768 769 <pre><!DOCTYPE HTML> 770 <html> 771 <strong><!-- where is this comment in the DOM? --></strong> 772 <head> 773 <title>Hello</title> 774 </head> 775 <body> 776 <p>Welcome to this example.</p> 777 </body> 778 </html></pre> 779 780 <p>With the tag removed, the document actually turns into the same as this:</p> 781 782 <pre><!DOCTYPE HTML> 783 <!-- where is this comment in the DOM? --> 784 <small><html></small> 785 <head> 786 <title>Hello</title> 787 </head> 788 <body> 789 <p>Welcome to this example.</p> 790 </body> 791 </html></pre> 792 793 <p>This is why the tag can only be removed if it is not followed by a comment: removing the tag 794 when there is a comment there changes the document's resulting parse tree. Of course, if the 795 position of the comment does not matter, then the tag can be omitted, as if the comment had been 796 moved to before the start tag in the first place.</p> 797 798 </div> 799 800 801 <p>An <code id=optional-tags:the-html-element-5><a href=semantics.html#the-html-element>html</a></code> element's <a href=#syntax-end-tag id=optional-tags:syntax-end-tag>end tag</a> may be omitted if 802 the <code id=optional-tags:the-html-element-6><a href=semantics.html#the-html-element>html</a></code> element is not immediately followed by a <a href=#syntax-comments id=optional-tags:syntax-comments-2>comment</a>.</p> 803 804 805 <p>A <code id=optional-tags:the-head-element><a href=semantics.html#the-head-element>head</a></code> element's <a href=#syntax-start-tag id=optional-tags:syntax-start-tag-3>start tag</a> may be omitted if 806 the element is empty, or if the first thing inside the <code id=optional-tags:the-head-element-2><a href=semantics.html#the-head-element>head</a></code> element is an 807 element.</p> 808 809 810 <p>A <code id=optional-tags:the-head-element-3><a href=semantics.html#the-head-element>head</a></code> element's <a href=#syntax-end-tag id=optional-tags:syntax-end-tag-2>end tag</a> may be omitted if the 811 <code id=optional-tags:the-head-element-4><a href=semantics.html#the-head-element>head</a></code> element is not immediately followed by a <a id=optional-tags:space-character href=infrastructure.html#space-character>space character</a> or a <a href=#syntax-comments id=optional-tags:syntax-comments-3>comment</a>.</p> 812 813 814 <p>A <code id=optional-tags:the-body-element><a href=semantics.html#the-body-element>body</a></code> element's <a href=#syntax-start-tag id=optional-tags:syntax-start-tag-4>start tag</a> may be omitted 815 if the element is empty, or if the first thing inside the <code id=optional-tags:the-body-element-2><a href=semantics.html#the-body-element>body</a></code> element is not a 816 <a id=optional-tags:space-character-2 href=infrastructure.html#space-character>space character</a> or a <a href=#syntax-comments id=optional-tags:syntax-comments-4>comment</a>, except if the 817 first thing inside the <code id=optional-tags:the-body-element-3><a href=semantics.html#the-body-element>body</a></code> element is a <code id=optional-tags:the-meta-element><a href=semantics.html#the-meta-element>meta</a></code>, <code id=optional-tags:the-link-element><a href=semantics.html#the-link-element>link</a></code>, 818 <code id=optional-tags:the-script-element><a href=scripting.html#the-script-element>script</a></code>, <code id=optional-tags:the-style-element><a href=semantics.html#the-style-element>style</a></code>, or <code id=optional-tags:the-template-element><a href=scripting.html#the-template-element>template</a></code> element. </p> 819 820 821 <p>A <code id=optional-tags:the-body-element-4><a href=semantics.html#the-body-element>body</a></code> element's <a href=#syntax-end-tag id=optional-tags:syntax-end-tag-3>end tag</a> may be omitted if the 822 <code id=optional-tags:the-body-element-5><a href=semantics.html#the-body-element>body</a></code> element is not immediately followed by a <a href=#syntax-comments id=optional-tags:syntax-comments-5>comment</a>.</p> 823 824 <div class=example> 825 826 <p>Note that in the example above, the <code id=optional-tags:the-head-element-5><a href=semantics.html#the-head-element>head</a></code> element start and end tags, and the 827 <code id=optional-tags:the-body-element-6><a href=semantics.html#the-body-element>body</a></code> element start tag, can't be omitted, because they are surrounded by white 828 space:</p> 829 830 <pre><!DOCTYPE HTML> 831 <html><strong> 832 </strong><head><strong> 833 </strong><title>Hello</title><strong> 834 </strong></head><strong> 835 </strong><body><strong> 836 </strong><p>Welcome to this example.</p> 837 </body> 838 </html></pre> 839 840 <p>(The <code id=optional-tags:the-body-element-7><a href=semantics.html#the-body-element>body</a></code> and <code id=optional-tags:the-html-element-7><a href=semantics.html#the-html-element>html</a></code> element end tags could be omitted without 841 trouble; any spaces after those get parsed into the <code id=optional-tags:the-body-element-8><a href=semantics.html#the-body-element>body</a></code> element anyway.)</p> 842 843 <p>Usually, however, white space isn't an issue.

<p>Then we can omit a number of tags without affecting the DOM:</p> 849 850 <pre><!DOCTYPE HTML><title>Hello</title><p>Welcome to this example.</p></pre> 851 852 <p>At that point, we can also add some

Because of this, this specification provides for a two-pass mechanism with an 1381 optional pre-scan. Implementations are allowed, as described below, to apply a simplified parsing 1382 algorithm to whatever bytes they have available before beginning to parse the document. Then, the 1383 real parser is started, using a tentative encoding derived from this pre-parse and other 1384 out-of-band metadata. If, while the document is being loaded, the user agent discovers a character 1385 encoding declaration that conflicts with this information, then the parser can get reinvoked to 1386 perform a parse of the document with the real encoding.</p> 1387 1388 <p id=documentEncoding>User agents must use the following algorithm, called the <dfn id=encoding-sniffing-algorithm>encoding 1389 sniffing algorithm</dfn>, to determine the character encoding to use when decoding a document in 1390 the first pass.

In general preparsing the source to find the encoding improves 1408 performance, as it reduces the need to throw away the data structures used when parsing upon 1409 finding the encoding information.

The 2408 state machine must start in the <a href=#data-state id=tokenization:data-state>data state</a>. Most states consume a single character, 2409 which may have various side-effects, and either switches the state machine to a new state to 2410 <i>reconsume</i> the same character, or switches it to a new state to consume the next character, 2411 or stays in the same state to consume the next character. Some states have more complicated 2412 behavior and can consume several characters before switching to another state. In some cases, the 2413 tokenizer state is also changed by the tree construction stage.</p> 2414 2415 <p>The exact behavior of certain states depends on the <a href=#insertion-mode id=tokenization:insertion-mode>insertion mode</a> and the 2416 <a href=#stack-of-open-elements id=tokenization:stack-of-open-elements>stack of open elements</a>. Certain states also use a <dfn id=temporary-buffer><var>temporary buffer</var></dfn> to track progress.</p> 2417 2418 <p>The output of the tokenization step is a series of zero or more of the following tokens: 2419 DOCTYPE, start tag, end tag, comment, character, end-of-file. DOCTYPE tokens have a name, a public 2420 identifier, a system identifier, and a <dfn id=force-quirks-flag><i>force-quirks flag</i></dfn>. When a DOCTYPE token 2421 is created, its name, public identifier, and system identifier must be marked as missing (which is 2422 a distinct state from the empty string), and the <i id=tokenization:force-quirks-flag><a href=#force-quirks-flag>force-quirks flag</a></i> must be set to 2423 <i>off</i> (its other state is <i>on</i>). Start and end tag tokens have a tag name, a <dfn id=self-closing-flag>self-closing flag</dfn>, and a list of attributes, each of which has a 2424 name and a value. When a start or end tag token is created, its <i id=tokenization:self-closing-flag><a href=#self-closing-flag>self-closing flag</a></i> must be unset (its other state is that it be set), and its attributes 2425 list must be empty. Comment and character tokens have data.</p> 2426 2427 <p>When a token is emitted, it must immediately be handled by the <a href=#tree-construction id=tokenization:tree-construction>tree construction</a> 2428 stage. The tree construction stage can affect the state of the tokenization stage, and can insert 2429 additional characters into the stream. (For example, the <code id=tokenization:the-script-element><a href=scripting.html#the-script-element>script</a></code> element can result in 2430 scripts executing and using the <a id=tokenization:dynamic-markup-insertion href=webappapis.html#dynamic-markup-insertion>dynamic markup insertion</a> APIs to insert characters 2431 into the stream being tokenized.)</p> 2432 2433 <p class=note>Creating a token and emitting it are distinct actions. It is possible for a token 2434 to be created but implicitly abandoned (never emitted), e.g. if the file ends unexpectedly while 2435 processing the characters that are being parsed into a start tag token.</p> 2436 2437 <p>When a start tag token is emitted with its <i id=tokenization:self-closing-flag-2><a href=#self-closing-flag>self-closing flag</a></i> set, if the flag is not 2438 <dfn id=acknowledge-self-closing-flag>acknowledged</dfn> when it is processed by the tree 2439 construction stage, that is a <a href=#parse-error id=tokenization:parse-error>parse error</a>.</p> 2440 2441 <p>When an end tag token is emitted with attributes, that is a <a href=#parse-error id=tokenization:parse-error-2>parse error</a>.</p> 2442 2443 <p>When an end tag token is emitted with its <i id=tokenization:self-closing-flag-3><a href=#self-closing-flag>self-closing flag</a></i> set, that is a <a href=#parse-error id=tokenization:parse-error-3>parse 2444 error</a>.</p> 2445 2446 <p>An <dfn id=appropriate-end-tag-token>appropriate end tag token</dfn> is an end tag token whose tag name matches the tag name 2447 of the last start tag to have been emitted from this tokenizer, if any. If no start tag has been 2448 emitted from this tokenizer, then no end tag token is appropriate.</p> 2449 2450 <p>Before each step of the tokenizer, the user agent must first check the <a href=#parser-pause-flag id=tokenization:parser-pause-flag>parser pause 2451 flag</a>.

For example, an XML toolchain might not be able to represent attributes with the name <code>xmlns</code>, since they conflict with the Namespaces in XML syntax. There is also some 6389 data that the <a href=#html-parser id=coercing-an-html-dom-into-an-infoset:html-parser-2>HTML parser</a> generates that isn't included in the DOM itself. This 6390 section specifies some rules for handling these issues.</p> 6391 6392 <p>If the XML API being used doesn't support DOCTYPEs, the tool may drop DOCTYPEs altogether.</p> 6393 6394 <p>If the XML API doesn't support attributes in no namespace that are named "<code>xmlns</code>", attributes whose names start with "<code>xmlns:</code>", or 6395 attributes in the <a id=coercing-an-html-dom-into-an-infoset:xmlns-namespace href=infrastructure.html#xmlns-namespace>XMLNS namespace</a>, then the tool may drop such attributes.</p> 6396 6397 <p>The tool may annotate the output with any namespace declarations required for proper 6398 operation.</p> 6399 6400 <p>If the XML API being used restricts the allowable characters in the local names of elements and 6401 attributes, then the tool may map all element and attribute local names that the API wouldn't 6402 support to a set of names that <em>are</em> allowed, by replacing any character that isn't 6403 supported with the uppercase letter U and the six digits of the character's Unicode code point 6404 when expressed in hexadecimal, using digits 0-9 and capital letters A-F as the symbols, in 6405 increasing numeric order.</p> 6406 6407 <p class=example>For example, the element name <code>foo<bar</code>, which can be 6408 output by the <a href=#html-parser id=coercing-an-html-dom-into-an-infoset:html-parser-3>HTML parser</a>, though it is neither a legal HTML element name nor a 6409 well-formed XML element name, would be converted into <code>fooU00003Cbar</code>, which 6410 <em>is</em> a well-formed XML element name (though it's still not legal in HTML by any means).</p> 6411 6412 <p class=example>As another example, consider the attribute <code>xlink:href</code>. 6413 Used on a MathML element, it becomes, after being <a href=#adjust-foreign-attributes id=coercing-an-html-dom-into-an-infoset:adjust-foreign-attributes>adjusted</a>, an attribute with a prefix "<code>xlink</code>" and a local 6414 name "<code>href</code>". However, used on an HTML element, it becomes an attribute with 6415 no prefix and the local name "<code>xlink:href</code>", which is not a valid NCName, and 6416 thus might not be accepted by an XML API. It could thus get converted, becoming "<code>xlinkU00003Ahref</code>".</p> 6417 6418 <p class=note>The resulting names from this conversion conveniently can't clash with any 6419 attribute generated by the <a href=#html-parser id=coercing-an-html-dom-into-an-infoset:html-parser-4>HTML parser</a>, since those are all either lowercase or those 6420 listed in the <a href=#adjust-foreign-attributes id=coercing-an-html-dom-into-an-infoset:adjust-foreign-attributes-2>adjust foreign attributes</a> algorithm's table.</p> 6421 6422 <p>If the XML API restricts comments from having two consecutive U+002D HYPHEN-MINUS characters 6423 (--), the tool may insert a single U+0020 SPACE character between any such offending 6424 characters.</p> 6425 6426 <p>If the XML API restricts comments from ending in a U+002D HYPHEN-MINUS character (-), the tool 6427 may insert a single U+0020 SPACE character at the end of such comments.</p> 6428 6429 <p>If the XML API restricts allowed characters in character data, attribute values, or comments, 6430 the tool may replace any U+000C FORM FEED (FF) character with a U+0020 SPACE character, and any 6431 other literal non-XML character with a U+FFFD REPLACEMENT CHARACTER.</p> 6432 6433 <p>If the tool has no way to convey out-of-band information, then the tool may drop the following 6434 information:</p> 6435 6436 <ul><li>Whether the document is set to <i id=coercing-an-html-dom-into-an-infoset:no-quirks-mode><a href=infrastructure.html#no-quirks-mode>no-quirks mode</a></i>, <i id=coercing-an-html-dom-into-an-infoset:limited-quirks-mode><a href=infrastructure.html#limited-quirks-mode>limited-quirks mode</a></i>, or 6437 <i id=coercing-an-html-dom-into-an-infoset:quirks-mode><a href=infrastructure.html#quirks-mode>quirks mode</a></i><li>The association between form controls and forms that aren't their nearest <code id=coercing-an-html-dom-into-an-infoset:the-form-element><a href=forms.html#the-form-element>form</a></code> 6438 element ancestor (use of the <a href=#form-element-pointer id=coercing-an-html-dom-into-an-infoset:form-element-pointer><code>form</code> element pointer</a> in the parser)<li>The <a id=coercing-an-html-dom-into-an-infoset:template-contents href=scripting.html#template-contents>template contents</a> of any <code id=coercing-an-html-dom-into-an-infoset:the-template-element><a href=scripting.html#the-template-element>template</a></code> elements.</ul> 6439 6440 <p class=note>The mutations allowed by this section apply <em>after</em> the <a href=#html-parser id=coercing-an-html-dom-into-an-infoset:html-parser-5>HTML 6441 parser</a>'s rules have been applied. For example, a <code><a::></code> start tag 6442 will be closed by a <code></a::></code> end tag, and never by a <code></aU00003AU00003A></code> end tag, even if the user agent is using the rules above to 6443 then generate an actual element in the DOM with the name <code>aU00003AU00003A</code> for 6444 that start tag.</p> 6445 6446 6447 6448 6449 6450 6451 <h4 id=an-introduction-to-error-handling-and-strange-cases-in-the-parser>12.2.8 An introduction to error handling and strange cases in the parser</h4> 6452 6453 <p><i>This section is non-normative.</i></p> 6454 6455 <p>This section examines some erroneous markup and discusses how the <a href=#html-parser id=an-introduction-to-error-handling-and-strange-cases-in-the-parser:html-parser>HTML parser</a> 6456 handles these cases.</p> 6457 6458 6459 <h5 id=misnested-tags:-b-i-/b-/i>12.2.8.1 Misnested tags: <b><i></b></i></h5> 6460 6461 <p><i>This section is non-normative.</i></p> 6462 6463 <p>The most-often discussed example of erroneous markup is as follows:</p> 6464 6465 <pre><p>1<b>2<i>3</b>4</i>5</p></pre> 6466 6467 <p>The parsing of this markup is straightforward up to the "3".

handling in tables is, for historical reasons, especially strange.
