XPath with default namespace

[Sanjoy Ghosh]

Hi,   I am essentially using the code from SimpleXPathAPI sample in the Xalan-C_1_8_0-windows_2000-msvc_60 samples programs to evaluate a series of XPath expressions.  The XML document that I am evaluating the XPath expressions against uses a bunch of XML namespaces.  I find that even for elements in the default namespace I have to qualify the element name with the namespace prefix in the XPath _expression_ for it to work.  Is there any way to make XPathEvaluator() recognize element names without a prefix as being in the default namespace?   The code that I am using is:     XalanSourceTreeDOMSupport  theDOMSupport;   XalanSourceTreeParserLiaison theLiaison( theDOMSupport);   theDOMSupport.setParserLiaison( &theLiaison);     const XalanDOMString   theFileName( _fileName.c_str(), _fileName.length());   const LocalFileInputSource  theInputSource( theFileName.c_str());   XalanDocument* const   theDocument = theLiaison.parseXMLStream( theInputSource);   assert( theDocument != 0);   XalanDocumentPrefixResolver  thePrefixResolver( theDocument);   XPathEvaluator     theEvaluator;    XalanNode* xpathNode = getXPathEvaluator().selectSingleNode( getDOMSupport(), node,      XalanDOMString( xpathIterator->getXPath().c_str()).c_str(), getPrefixResolver());   The XML document I am using is:   <FpML version="4-1" dswgVersion = "0-4" xsi:type="dswg:PositionReport" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:fpml = "http://www.fpml.org/2004/FpML-4-1" xmlns:dswg = "http://www.dswg.org/position-reporting" xmlns:dsig = "http://www.w3.org/2000/09/xmldsig#" xsi:schemaLocation="http://www.fpml.org/2004/FpML-4-1 schema/fpml-main-4-1.xsd http://www.dswg.org/position-reporting schema/dswg-0-4.xsd" xmlns="http://www.fpml.org/2004/FpML-4-1">   The XPath I am trying to evaluate is:   dswg:positionSummary/fpml:equitySwap/fpml:productType "fpml" is the default namespace.  But if I remove the prefix from the _expression_ above it doesn't work. Is there any way to make the following evaluate properly? dswg:positionSummary/equitySwap/productType   Thanks, Sanjoy
