Hi, I'm trying to inject default attributes into a document from an XML Schema during parsing. I set up a validation context and set the XML_SCHEMA_VAL_VC_I_CREATE option on it, which, if I understand the docs correctly, tells the validator to create defaulted/fixed attributes if they do not exist already. Then I inject the validation context into the parser using "xmlSchemaSAXPlug()".
The schema document I use is ''' <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";> <xsd:element name="a" type="AType"/> <xsd:complexType name="AType"> <xsd:sequence minOccurs="4" maxOccurs="4"> <xsd:element name="b" type="BType" /> </xsd:sequence> </xsd:complexType> <xsd:complexType name="BType"> <xsd:attribute name="hardy" type="xsd:string" default="hey" /> </xsd:complexType> </xsd:schema> ''' The document I parse is ''' <a><b hardy="ho"/><b/><b hardy="ho"/><b/></a> ''' The document validates. However, no default attributes are inserted, neither with my code nor with xmllint (which doesn't seem to support that anyway). When I debug into the validator code in xmlschemas.c, I get to line 25351 (libxml2 2.7.3): ''' /* * Get the owner element; needed for creation of default attributes. * This fixes bug #341337, reported by David Grohmann. */ if (vctxt->options & XML_SCHEMA_VAL_VC_I_CREATE) { xmlSchemaNodeInfoPtr ielem = vctxt->elemInfos[vctxt->depth]; ==> if (ielem && ielem->node && ielem->node->doc) defAttrOwnerElem = ielem->node; } ''' but "ielem->node" is NULL every time it gets there, so this doesn't fly. Is there anything else I have to do to make this work?
