title: Select node without namespace with XPath
body: <p>I have a xml like</p>
  
  <pre><code>&lt;root xmlns:ns1="http://foo"&gt;
      &lt;ns1:child1&gt;Text&lt;/ns1:child1&gt;
      &lt;ns1:child2&gt;Number&lt;/ns1:child2&gt;
  &lt;/root&gt;
  </code></pre>
  
  <p>Now I get this from different persons, so that for example person 2 sends me another message with the same structure like</p>
  
  <pre><code>&lt;root xmlns:anotherNs="http://foo"&gt;
      &lt;anotherNs:child1&gt;Another Text&lt;/anotherNs:child1&gt;
      &lt;anotherNs:child2&gt;Another Number&lt;/anotherNs:child2&gt;
  &lt;/root&gt;
  </code></pre>
  
  <p>So the only difference is the name of the namespace. How can I select the content of child2 for both xml's with one XPath expression?</p>
  
  <p>Something like "/root/child2" or "//child2" did not work.</p>
