Official DFG Viewer (old code) with SRU example from documentation:

In the test above only the <dv:span class="highlight">Posten</dv:span> was returned.

If there are also <span> elements without class="highlight" like in the official documentation and in the following XML, the latest code hangs with "Lade Ergebnisse ...".
