Hello,
I have been looking through the xerces mail archives, and still cannot
seem to get my code to work. My basic question is: if I am walking the
DOM tree using xerces-c++, how can I get at the PSVI information from a
DOMNode pointer (which I call curNode in the code samples below)? I found
this code to work:
const
XMLCh *typeName;
DOMPSVITypeInfo *psviType;
psviType = (DOMPSVITypeInfo*)
curNode->getInterface(XMLUni::fgXercescInterfacePSVITypeInfo);
if (!psviType)
return DMT_NONE;
typeName =
psviType->getStringProperty(DOMPSVITypeInfo::PSVI_Type_Definition_Name);
if (!typeName)
return DMT_NONE;
if (!strcmp(S(typeName), "string"))
return DMT_STRING;
if (!strcmp(S(typeName), "boolean"))
return DMT_BOOL;
if (!strcmp(S(typeName), "integer") ||
!strcmp(S(typeName), "short") ||
!strcmp(S(typeName), "long"))
return DMT_INT;
if (!strcmp(S(typeName), "double") ||
!strcmp(S(typeName), "float"))
return DMT_DOUBLE;
which is great, but it only handles finding the type of an element when the type is an attribute on that element. But I want to find out everything about an element, including when it is a complex type or a simple type with restrictions. For instance, if the schema says:
<xs:element name="Years">
<xs:simpleType>
<xs:restriction base="xs:integer">
<xs:minInclusive value="1900"/>
<xs:maxInclusive value="3000"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
how can I find out the minInclusive and maxInclusive values straight from the DOMNode pointer to the "Years" element? I have tried code such as:
PSVIElement *psviElem = (PSVIElement *) curNode;
XSTypeDefinition *def = psviElem->getTypeDefinition();
cout<<psviElem->getValidity()<<endl;
enum XSTypeDefinition::TYPE_CATEGORY cat = def->getTypeCategory();
cout<<cat<<endl;
if (cat == XSTypeDefinition::COMPLEX_TYPE)
{
cout<<"yes"<<endl;
}
but this code produces garbage in the cout's.
Can you help me?
Thanks much,
Jim
