Question

i know there are plenty of this topic in this page but sadly, i still cant get my solution..

here is my xml code:

Answer 1

You need to use a NamespaceContext for your XPath expression. You can read more about how to do this here

Answer 2

You are going to have to create a subclass of javax.xml.namespace.NamespaceContext and set it on xpath:

xpath.setNamespaceContext(new NamespaceContext() {

    @SuppressWarnings("rawtypes")
    @Override
    public Iterator getPrefixes(final String namespaceURI) {
        return Collections.singleton("ns1").iterator();
    }

    @Override
    public String getPrefix(final String namespaceURI) {
        return "ns1";
    }

    @Override
    public String getNamespaceURI(final String prefix) {
        return "http://www.sea.com";
    }
});

Then you can add the namespace prefix to the XPath expression:

XPathExpression expr = xpath.compile("//ns1:PayrollCost/*/text()");
