XML DOM

I have an XML document as a string $strXml, that looks a little like this:

<recordset>
<row>
<userid>1</userid>
<username>Bob</username>
<password>Rover</username>
</row>
<row>
<userid>2</userid>
<username>Fred</username>
<password>Fido</username>
</row>
</recordset>

What's the best way to grab a single value from this document? In the past
(in
VB), I have loaded the XML into a DOM Document, and used an XPath query to
select the data I want, and then bung the output into a string.

Any suggestions?

Thanks
Ian

You can do the same bunging in PHP if your php setup has domxml enabled.
Or you can use the (faster, but batch-like) SAX parser.
