SimpleXPathAPI & my app are different.
Here is my sample code. Pls let me know if there is anything wrong.
I am using xerces parser because I need to read/edit/create the XML documents
===================================================
XercesDOMParser* m_pXercesDOMParser;
DOMDocument* m_pDOMDocument;
XalanDocument* m_prefXalanDocument;
XPathEvaluator* m_pXPathEvaluator;
XercesDOMSupport* m_pXercesDOMSupport;
XercesParserLiaison* m_pXercesParserLiaison;
XalanDocumentPrefixResolver* m_pXalanDocumentPrefixResolver;
XercesDocumentWrapper* m_prefXercesDocumentWrapper;
XObject* prefXObject = 0;
m_pXmlFile = pFileName;
m_pXercesDOMParser = new xercesc::XercesDOMParser;
m_pXercesDOMParser->parse((const XMLCh*)m_pXmlFile.c_str());
m_pDOMDocument = m_pXercesDOMParser->getDocument();
m_prefXalanDocument =
m_pXercesParserLiaison->createDocument(m_pDOMDocument,0,1);
m_pXalanDocumentPrefixResolver
= new XalanDocumentPrefixResolver(m_prefXalanDocument);
m_prefXercesDocumentWrapper=m_pXercesParserLiais->mapDocumentToWrapper(m_prefXalanDocument);
m_pXalanContextNode =
m_pXPathEvaluator->selectSingleNode(*m_pXercesDOMSupport,m_prefXalanDocument,
"/catalog/book".c_str(),*m_pXalanDocumentPrefixResolver);
m_pXObjectPtr = new
XALAN_CPP_NAMESPACE::XObjectPtr((m_pXPathEvaluator->evaluate(
*m_pXercesDOMSupport,m_pXalanContextNode,
"child::[EMAIL PROTECTED]", *m_pXalanDocumentPrefixResolver)));
prefXObject = m_pXObjectPtr->get();
if(XObject::eObjectType::eTypeNodeSet == prefXObject->getType())
{
NodeRefList pTemp(prefXObject->nodeset());
iTempCount = pTemp.getLength();
// iTempCount is ZERO
}
===================================================
Thanks
