How to compile a stylesheet whose source is a Xerces-c DOMDocument

Hi,

Is it possible to compile a stylesheet whose source is a Xerces DOMDocument?

In the following example, invoking compileStylesheet causes a segv:

    Transformer::Transformer(DOMDocument *pSSDoc) {
        XMLPlatformUtils::Initialize();

        std::unique_ptr<XercesParserLiaison> parserLiaisonPtr(new XercesParserLiaison());
        std::unique_ptr<XercesDOMSupport> xercesDOMSupportPtr(new XercesDOMSupport(*parserLiaisonPtr.get()));

        XalanDocument *pXalanDoc = parserLiaisonPtr->createDocument(pSSDoc,true,true,true);

        xalanc::XalanNode *pRoot = pXalanDoc->getDocumentElement();
        int res = _pXalanTransformer->compileStylesheet(pRoot, _pSS);

    }

Hi Paul,


I don't have a direct answer the the question, but I can't see why it 
shouldn't work in principle.  Could you build xerces, xalan and your 
application with debug symbols and get a stacktrace so we can see where 
it went wrong?  Maybe it's something simple we can get fixed.


Thanks,

Roger

This was my fault. I needed to initialize XalanTransformer:

    Transformer::Transformer(DOMDocument *pSSDoc) {
        XMLPlatformUtils::Initialize();

        std::unique_ptr<XercesParserLiaison> parserLiaisonPtr(new XercesParserLiaison());
        std::unique_ptr<XercesDOMSupport> xercesDOMSupportPtr(new XercesDOMSupport(*parserLiaisonPtr.get()));

        XalanDocument *pXalanDoc = parserLiaisonPtr->createDocument(pSSDoc,true,true,true);

        xalanc::XalanNode *pRoot = pXalanDoc->getDocumentElement();

        xalanc::XalanTransformer::initialize();
        _pXalanTransformer = new XalanTransformer();
        int res = _pXalanTransformer->compileStylesheet(pRoot, _pSS);

With this change, I am able to use a xerces-c::DOMDocument as a stylesheet.

Hi,

Is it possible to compile a stylesheet whose source is a Xerces DOMDocument?

In the following example, invoking compileStylesheet causes a segv:

    Transformer::Transformer(DOMDocument *pSSDoc) {
        XMLPlatformUtils::Initialize();

        std::unique_ptr<XercesParserLiaison> parserLiaisonPtr(new XercesParserLiaison());
        std::unique_ptr<XercesDOMSupport> xercesDOMSupportPtr(new XercesDOMSupport(*parserLiaisonPtr.get()));

        XalanDocument *pXalanDoc = parserLiaisonPtr->createDocument(pSSDoc,true,true,true);

        xalanc::XalanNode *pRoot = pXalanDoc->getDocumentElement();
        int res = _pXalanTransformer->compileStylesheet(pRoot, _pSS);

    }

Paul
