Request handling problem (java-script)

[Äpfel]

I have a problem handling my Request within my Widget.

I do two kinds of request which should both work quite similar, though one doesnt work at all.
Requested XML looks like this:

<YMResult Version="2.0" ResultType="POI_DETAIL">
 <PoiDetail>
  <Adr>
  <SName>xxx</SName>
  <Twn>xxx</Twn>
</Adr>
<BNames>Tankstellen</BNames>
</PoiDetail>
</YMResult>

I get the request like that:

xmlResult = this.httpReq.responseXML;

then i want to extract the values:

Something like that should work:

var poiList = xmlResult.documentElement.getElementsByTagName("PoiDetail");

But following code leads to an exception:

alert(poiList.length);

Here comes the kicker: The Code runs in Aptana-Plugin and in Firefox. But it does not on my N95 developement Phone. Is there any possibility to debug java-script widget code on my phone or any other environement where i can do so? Or has anybody have a clue what i might have done wrong?

solved: wrt parsed the "&" to &#38 which had to be replaced to a "&" again.

wtf i say
