Parse XML with XPath & namespaces in Java
- by ripper234
Can you help me adjust this code so it manages to parse the XML? If I drop the XML namespace it works:
String webXmlContent = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
"<foo xmlns=\"http://foo.bar/boo\"><bar>baz</bar></foo>";
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
domFactory.setNamespaceAware(true);
DocumentBuilder builder = domFactory.newDocumentBuilder();
org.w3c.dom.Document doc = builder.parse(new StringInputStream(webXmlContent));
NamespaceContextImpl namespaceContext = new NamespaceContextImpl();
namespaceContext.startPrefixMapping("foo", "http://www.w3.org/2001/XMLSchema-instance");
XPath xpath = XPathFactory.newInstance().newXPath();
xpath.setNamespaceContext(namespaceContext);
XPathExpression expr = xpath.compile("/foo/bar");
Object result = expr.evaluate(doc, XPathConstants.NODESET);
NodeList nodes = (NodeList) result;
System.out.println("Got " + nodes.getLength() + " nodes");
