1 * Summary: internals routines and limits exported by the parser. 2 * Description: this module exports a number of internal parsing routines 3 * they are not really all intended for applications but 4 * can prove useful doing low level processing. 5 * 6 * Copy: See Copyright for the status of this software. 7 * 8 * Author: Patrick Monnerat <pm (a] datasphere.ch>, DATASPHERE S.A. 9 10 /if not defined(XML_PARSER_INTERNALS_H__) 11 /define XML_PARSER_INTERNALS_H__ 12 13 /include "libxmlrpg/xmlversion" 14 /include "libxmlrpg/xmlTypesC" 15 /include "libxmlrpg/parser" 16 /include "libxmlrpg/HTMLparser" 17 /include "libxmlrpg/chvalid" 18 19 * xmlParserMaxDepth: 20 * 21 * arbitrary depth limit for the XML documents that we allow to 22 * process.
