    text
    copied!<p>I have the following soap message:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"&gt;&lt;soap:Header&gt;&lt;wsse:Security env:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"&gt;&lt;wsse:UsernameToken xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"&gt;&lt;wsse:Username&gt;test&lt;/wsse:Username&gt;&lt;wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText"&gt;11111111&lt;/wsse:Password&gt;&lt;/wsse:UsernameToken&gt;&lt;/wsse:Security&gt;&lt;/soap:Header&gt; &lt;soap:Body xmlns:ns1="http://www.acme.co.za"&gt; &lt;ns1:pingMeCallback&gt; &lt;ns1:message&gt;abc&lt;/ns1:message&gt; &lt;/ns1:pingMeCallback&gt; &lt;/soap:Body&gt; &lt;/soap:Envelope&gt; </code></pre> <p>I need to use xpath to read in the message value. My code is as follows:</p> <pre><code> DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); factory.setNamespaceAware(true); DocumentBuilder builder = factory.newDocumentBuilder(); InputSource data = new InputSource(in); Node doc = builder.parse("ping.xml"); // set up a document purely to hold the namespace mappings DOMImplementation impl = builder.getDOMImplementation(); Document namespaceHolder = impl.createDocument("http://www.acme.co.za/","f:namespaceMapping", null); Element root = namespaceHolder.getDocumentElement(); root.setAttributeNS("http://www.w3.org/2000/xmlns/", "xmlns:SOAP","http://schemas.xmlsoap.org/soap/envelope/"); root.setAttributeNS("http://www.w3.org/2000/xmlns/", "xmlns:ns1","http://schemas.xmlsoap.org/soap/envelope/"); NodeList results = XPathAPI.selectNodeList(doc,"/SOAP:Envelope/SOAP:Body/ns1:pingMeCallback/ns1:message",root); for (int i = 0; i &lt; results.getLength(); i++) { Node result = results.item(i); XObject value = XPathAPI.eval(result, "string()"); System.out.println(value.str()); } </code></pre> <p>My code prints out nothing. Can anybody find out what I am doing wroing?</p>
