Sorry for resurrecting this issue from 6 weeks ago. I tried the suggestion that Stephen gave to me for doing XSD validation on an input XML using the Castor XML Mapping method:
1) Instantiate/configure a SAX parser (specify the external-schema-location feature) 2) Instantiate/configure an Unmarshaller instance 3) Call createHandler() on the Unmarshaller object to get an UnmarshalHandler which implements ContentHandler and ErrorHandler 4) Set the parser's content handler to the UnmarshalHandler object 5) Set the parser's error handler to the UnmarshalHandler object 6) Parse the document 7) Call getObject on the UnmarshalHandler to retrieve the root object so the code looks something like this: UnmarshalHandler unmarshalHandler = unmarshaller.createHandler(); // Set the parser's content handler to the // UnmarshalHandler object xmlReader.setContentHandler(unmarshalHandler); // Set the parser's error handler to the // UnmarshalHandler object xmlReader.setErrorHandler(unmarshalHandler); // Parse the xml document xmlReader.parse(inputSource); This solution has worked for me. The only problem is that on my project we have a requirement to show all XSD validation errors for an input XML. The problem with Castor's Unmarshaller handler is that it only reports the first XSD validation error. So for example, if an XML document fails because of 3 different XSD validation errors, then Castor's Unmarshaller error handler only shows the first XSD validation error. Is there an easy way around this? How can I get it to give me all the XSD validation errors?
