Ingoring xmlns attribute with XQuery

  • Hi There,
    I have an xml file that begins like this:

    <?xml version="1.0" encoding="UTF-8"?>
    <Signature xmlns="http://www.someplace.org/sig" isClass="true">
    <Header>my header</Header>
    <Version Number="1.1" Date="2007.04.30"/>

    I've created a simple XQuery to return the Header information, which works only if the xmlns attribute DOESN'T exist in the Signature element.  So I was wondering if there is a way I can have saxon ignore the xmlns attribute and continue with the query?  Any help is greatly appreciated!
    
    Here's the code that I use to create and execute my query:
    

    Configuration config = new Configuration();
    config.setXMLVersion(Configuration.XML11);

    StaticQueryContext sqc = new StaticQueryContext(config);

    XQueryExpression exp = sqc.compileQuery(" let $doc := . " +
    " for $v in $doc//Signature " +
    " return $v/Header");
    DynamicQueryContext dynamicContext = new DynamicQueryContext(config);
    dynamicContext.setContextItem(config.buildDocument(new StreamSource(new File("C:/signature.xml"))));

    exp.run(dynamicContext, new StreamResult(new File("C:/result.html")), null);

    Thanks in Advance,
    Chris

      XQuery coding questions (that have nothing specifically to do with the Saxon implementation) are probably best posted on the XQuery Talk list at x-query.com.

      You can't ignore the namespace in which your source elements appear - the namespace is an intrinsic part of the element name of every element in your document. What you can do is to include

      declare default element namespace "http://www.someplace.org/sig";

      in the query prolog.

      Note however that this will also affect any unprefixed element names in element constructors.
