Firstly both documents should be using a well defined namespace. If thats the case then the prefix doesn't matter - you can just bind whatever prefix you want to the expected namespace (e.g. SOAP's namespace URI) then use your own prefix in XPath - irrespective of the prefixes used in the document.
e.g. // register prefixes with my factory Map uris = new HashMap(); uris.put( "SOAP-ENV", "http://schemas.xmlsoap.org/soap/envelope/"; ); DocumentFactory factory = new DocumentFactory(); factory.setXPathNamespaceURIs( uris ); // now parse a document using my factory SAXReader reader = new SAXReader(); reader.setDocumentFactory( factory ); Document doc = reader.read( "soap.xml" ); // now lets use the prefixes Node element = doc.selectSingleNode( "/SOAP-ENV:Envelope/SOAP-ENV:Body" ); Or if the prefix or namespace URIs are unknown, then you could use the XPath expression... *[local-name()='Body'] Which is a bit ugly but then its rare to not care about the namespace URI.
