When you get a chance, can you take a look at api.client.php? Basically, what I have will work if the response is like this:
<response>
<parameters>
<whatever>2</whatever>
<something>4</something>
</parameters>
</response>

But what I need is for it to generate an array with the sub values too…. So I can do like

<response>
<parameters>
<server>
<id>1</id>
<blah>2</blah>
</server>
<server>
<id>4></id>
</server>
</parameters>
</response>
