Question

I am trying to create an org.w3c.dom.Document object from an xml string. I have followed what many have suggested in other questions but the document ends up empty. What is wrong with the following code?

DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.parse(new InputSource(new StringReader(response.getResponseText())));

And the xml text in the string looks like the following (this comes from response.getResponseText())

<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing">

Can anyone see what is wrong with my code? I ultimately just want to run a couple of xpath queries on the document…

Answer 1

I would suggest to start with setting docFactory.setNamespaceAware(true);, otherwise the parsing, the DOM built and the XPath implementation will not be able to work with XML with namespaces as you have posted.
