| 34 | * Canonical form of an XML document could be created if and only if
|
|---|
| 35 | * a) default attributes (if any) are added to all nodes
|
|---|
| 36 | * b) all character and parsed entity references are resolved
|
|---|
| 37 | * In order to achive this in libxml2 the document MUST be loaded with
|
|---|
| 38 | * following global setings:
|
|---|
| 39 | *
|
|---|
| 40 | * xmlLoadExtDtdDefaultValue = XML_DETECT_IDS ã XML_COMPLETE_ATTRS;
|
|---|
| 41 | * xmlSubstituteEntitiesDefault(1);
|
|---|
| 42 | *
|
|---|
| 43 | * or corresponding parser context setting:
|
|---|
| 44 | * xmlParserCtxtPtr ctxt;
|
|---|
| 45 | *
|
|---|
| 46 | * ...
|
|---|
| 47 | * ctxt->loadsubset = XML_DETECT_IDS ã XML_COMPLETE_ATTRS;
|
|---|
| 48 | * ctxt->replaceEntities = 1;
|
|---|
| 49 | * ...
