Re: HTTPAPI, SOAP, and parsing the returned XML

[Scott Klement <sk@xxxxxxxxxxxxxxxx>]

If you look at the raw data being returned from the web service, does it 
look something like the following:

<soap:Envelope whatever-whatever>
   <soap:Body whatever>
     &lt;ADStart&gt;&lt;error code="0" text="NO_ERROR"
     /&gt;&lt;ticket&gt;fe81cb7e-fd9e-411b-b3fd-b9c5729728f7
     &lt;/ticket&gt;&lt;/ADStart&gt;
   </soap:Body>
</soap:Envelope>

What I mean is... are the <, > and & characters escaped so that they 
won't be treated as XML tags, as they are in the above example?  If so, 
that's a very common issue.  The solution is to have the contents of the 
'Body' element saved to a file (or a string if it's small enough) and 
then parse that file/string separately using http_parse_xml_stmf() or 
http_parse_xml_string()

However, your description doesn't QUITE match that symptom... but it's 
very close.  So I might be completely wrong in this diagnosis.  If I am, 
then I really need more information than just "the XML parser isn't 
working" (which is about all I can get from your description).  I'll 
need a way to reproduce the problem.
