Alberto,
I used the code you just gave to me. I'm trying to get a pointer to a QName
object, but it seems that that object is invalid.
I get the pointer to QName, but then no matter which method of QName I call
I get an exception (Access in invalid memory).
XMLAttDefList& attrIter=pComplexType->getAttDefList();
for(unsigned int i=0;i<attrIter.getAttDefCount();i++)
{
XMLAttDef& attr=attrIter.getAttDef(i);
XMLAttDef::DefAttTypes ty = attr.getDefaultType();
if(ty == XMLAttDef::Prohibited)
continue;
SchemaAttDef* pAttr=(SchemaAttDef*)&attr;
QName* qname = pAttr->getAttName();
unsigned int uriid = qname->getURI(); --> I always get an exception here
// qname object is invalid
}
I noticed that you get the ComplexTypeInfo by reference and not a pointer
--> ComplexTypeInfo& curTypeInfo = complexTypeEnum.nextElement(); <--
(how do you do that?... I mean what is "complexTypeEnum?"...)
In contrast, I get a pointer to the ComplexTypeInfo object like the way
you indicated in one of your posts:
// xmlnode is a DOMNode*...
DOMPSVITypeInfo* psviType =
(DOMPSVITypeInfo*)xmlnode->getInterface(XMLUni::fgXercescInterfacePSVITypeIn
fo);
if (!psviType)
return false;
const XMLCh* typeName =
psviType->getStringProperty(DOMPSVITypeInfo::PSVI_Type_Definition_Name);
if (!typeName)
return false;
const XMLCh* typeURI =
psviType->getStringProperty(DOMPSVITypeInfo::PSVI_Type_Definition_Namespace)
;
XSTypeDefinition::TYPE_CATEGORY typeType =
(XSTypeDefinition::TYPE_CATEGORY)psviType->getNumericProperty(DOMPSVITypeInf
o::PSVI_Type_Definition_Type);
Grammar* pGrammar=FDOMParser->getGrammar(typeURI);
if(!pGrammar && pGrammar->getGrammarType()!=Grammar::SchemaGrammarType)
return false;
SchemaGrammar* pSchema=(SchemaGrammar*)pGrammar;
if(typeType!=XSTypeDefinition::COMPLEX_TYPE)
return true;
XMLBuffer typeKey(1023);
typeKey.set(typeURI);
typeKey.append(chComma);
typeKey.append(typeName);
RefHashTableOf<ComplexTypeInfo>* pSchemaTypes =
pSchema->getComplexTypeRegistry();
ComplexTypeInfo* pComplexType =
pSchemaTypes->get(typeKey.getRawBuffer());
Thanks again, you help is being priceless!
Nicolas

You're right, I read my code too quickly.... This is what I do:
ComplexTypeInfo& curTypeInfo = complexTypeEnum.nextElement();
if(curTypeInfo.hasAttDefs())
{
XMLAttDefList& attrIter=curTypeInfo.getAttDefList();
for(unsigned int i=0;i<attrIter.getAttDefCount();i++)
{
XMLAttDef& attr=attrIter.getAttDef(i);
XMLAttDef::DefAttTypes ty = attr.getDefaultType();
if(ty == XMLAttDef::Prohibited)
continue;
SchemaAttDef* pAttr=(SchemaAttDef*)&attr;
if(pAttr->getAttName()->getURI()==qname.getURI())
szName=pAttr->getFullName();
else
szName=getFullName(pAttr->getAttName());
}
}
and this code has never failed.
If this doesn't help you, can you send the entire testcase you are
using (C++ files and schema)?
Thanks,
Alberto
