37 | * Canonical form of an XML document could be created if and only if |
---|
38 | * a) default attributes (if any) are added to all nodes |
---|
39 | * b) all character and parsed entity references are resolved |
---|
40 | * In order to achive this in libxml2 the document MUST be loaded with |
---|
41 | * following global setings: |
---|
42 | * |
---|
43 | * xmlLoadExtDtdDefaultValue = XML_DETECT_IDS | XML_COMPLETE_ATTRS; |
---|
44 | * xmlSubstituteEntitiesDefault(1); |
---|
45 | * |
---|
46 | * or corresponding parser context setting: |
---|
47 | * xmlParserCtxtPtr ctxt; |
---|
48 | * |
---|
49 | * ... |
---|
50 | * ctxt->loadsubset = XML_DETECT_IDS | XML_COMPLETE_ATTRS; |
---|
51 | * ctxt->replaceEntities = 1; |
