Hi!
There is an example. The buffer is what I want to parse, the NS xsi is defined in
soap.xml.
===========================================================================================
char *buffer = "<xsi:getsumReturn xsi:type=\"xsd:int\">9</xsi:getsumReturn>";
xmlInitParser();
LIBXML_TEST_VERSION
xmlLoadExtDtdDefaultValue = XML_DETECT_IDS | XML_COMPLETE_ATTRS;
xmlSubstituteEntitiesDefault(1);
/* load template */
doc = xmlParseFile("soap.xml");
if ((doc == NULL) || (xmlDocGetRootElement(doc) == NULL)){
fprintf(stderr, "Error: unable to parse file \"%s\"\n", "soap.xml");
goto done;
}
ret = xmlParseInNodeContext(xmlDocGetRootElement(doc), buffer, xmlStrlen(buffer),
XML_PARSE_NOENT, &encNode);
if(ret < 0) {
fprintf(stderr, "Error: xmlParseInNodeContext.\n");
goto done;
}
xmlAddChild(xmlDocGetRootElement(doc), encNode);
xmlDocDump(stdout, doc);
xmlFreeDoc(doc); <----- The error : Segmentation fault occur!
==============================================================================================
soap.xml
===========================================
<?xml version="1.0" encoding="UTF-8"?>
<Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";></Envelope>
===========================================
BTW, I use function xmlParseInNodeContext() because after encrypt node
<xsi:getsumReturn xsi:type="xsd:int">9</xsi:getsumReturn>, the xsi NS will not found
when decrypt it. If you have another good method I will replace it.
Thx!
