Examples of org.apache.xpath.objects.XObject.nodeset()

org.apache.xpath.objects.XObject.nodeset()
Cast result object to a nodelist. Always issues an error. @return null @throws javax.xml.transform.TransformerException


    // Execute the XPath, and have it return the result
    XObject list = eval(contextNode, str, namespaceNode);


    // Have the XObject return its result as a NodeSetDTM.                
    return list.nodeset();
