Using XPath to match a key/value paired XML message

In one of my current projects, we have an XML message that looks a little like this.

    <values>van der Sijpt<values>

For testing purposes, I want to use XPath to get values from this, i.e. match first-name to Angelo.

After some fiddling, I wound up with this slightly ugly contraption. Might be useful for you one day, though I hope you can be spared...
