I'm trying to select a node from a DOM using the XPathAPI.selectSingleNode() call. Everything works fine unless the XML has namespaces and I try to reference them in my XPath expression.
For instance, take the following sample SOAP fault: <SOAP-ENV:Envelope xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"; xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";> <SOAP-ENV:Body> <SOAP-ENV:Fault> <faultcode>Client</faultcode> <faultstring>The SOAP message request did not contain the appropriate security token credentials required to execute a request on the server.</faultstring> <faultactor>Server</faultactor> <detail> <e:yourfaultdetails xmlns:e="mynamespace"> <message>The SOAP request did not contain a valid security token.</message> <errorcode>1000000</errorcode> </e:yourfaultdetails> </detail> </SOAP-ENV:Fault> </SOAP-ENV:Body> </SOAP-ENV:Envelope> In my Java code, when I call XPathAPI.selectSingleNode(doc, "/SOAP-ENV:Envelope/SOAP-ENV:Body/SOAP-ENV:Fault/faultcode"); It fails saying javax.xml.transform.TransformerException: Prefix must resolve to a namespace: SOAP-ENV So, I figure I need to use the selectSingleNode() API where I pass in a namespace node as the third parameter. BUT, FOR THE LOVE OF XALAN, WHAT IS A NAMESPACE NODE?! I've tried passing it the document root of the above SOAP fault. I've tried creating a new document with a single element with the SOAP-ENV namespace declared and passing that element as the third parameter. I've even declared the namespace in an element and passed the attribute that contains the "xmlns:SOAP-ENV" name. Please, someone, tell me what I'm doing wrong. Thanks, Scott
