hi
I am running into problem while trying to extract an xs:any as a typed
XMLObject.
I am writing code that is not aware of the actual concrete types but
responsible for inserting and extracting XmlObjects as xs:any (and
dynamically converting to concrete type while extracting)
I have following:
<xs:complexType name="MyType">
...
</xs:complexType>
<xs:element name="MyElement" type="MyType"/>
My code receives MyElementDocument and it inserts it as xs:any in a parent
element using XmlCursor and this works fine. But when I extract the xs:any
using parent.selectPath("./*") I get an XML fragment which is of class
XmlAnyTypeImpl with the contents of MyType and the XmlCursor's name same as
that of the MyElementDocument's QName. (This makes sense since document can
only be an independent instance and not a child)
Subsequent code to do changeType (to dynamically convert to concrete
Element) on this untyped XmlObject fails to work. Here is my code to do
dynamic conversion:
SchemaTypeLoader typeLoader = XmlBeans.getContextTypeLoader();
XmlObject[] anyChildren = parent.selectPath("./*");
XmlObject anyChild = anyChildren[0];
XmlCursor cursor = anyChild.newCursor();
QName qName = cursor.getName();
// The qName here is the QName of MyElementDocument
SchemaType schType = typeLoader.findDocumentType(qName);
XmlObject typedObj = anyChild.changeType(schType);
if (typedObj == anyChild)
{
System.out.println("Could not change type");
}
else
{
// This object can now be treated as MyElementDocument
}
Am I doing something wrong here? Is there some other way to achieve this
without requiring to know the actual concrete XmlObject and its Factory?
thanks for the help.
regards
kapil
