Re: HTTPAPI, SOAP, and parsing the returned XML

   Glenn, may be you can send ( or copy-paste) the debug file ?

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.

   I'm trying my first application with HTTPAPI.  I'm using the
   http_url_post_xml to send a SOAP request to a web service.  I'm
   getting an XML file back that looks something like this:


   <ADStart><error code="0" text="NO_ERROR"
   /><ticket>fe81cb7e-fd9e-411b-b3fd-b9c5729728f7</ticket></ADStart>


   I'm using the incoming procedure in a lot of the examples to attempt
   to parse the returned XML.  The first name comes back as ADStart, with
   a value of: error code="0" text="NO_ERROR"
   /><ticket>fe81cb7e-fd9e-411b-b3fd-b9c5729728f7</ticket>


   I'm trying to extract the ticket value, but not quite sure how to get
   there!  The next time the Incoming procedure is invoked, it simply
   returns the end of the soap body followed by the envelope.  Is the
   fact that the web service is returning the error code line and that
   line isn't enclosed in starting and ending tags the issue?  If so, do
   you have any suggestion of how to get around it?


   Thanks for your help!

   Glenn
