Re: Enhancement request for module HTTPXMLR4

Hi Thomas,

If I understand what you're saying about http_parse_xml_raw(), I'm not 
sure that it'll help?  It'll work okay if the response is an ordinary 
SOAP message, but if the result contains attachments, you'd have to 
receive the whole thing in your own callback in order to figure out 
which part is the SOAP -- and since it contains attachments, that could 
potentially be many megabytes (maybe even gigabytes) of data.  I 
wouldn't want to try to store that in memory!

Hmmm...  I wonder if it wouldn't make more sense to use 
http_url_post_raw2() and simply write the output to a temporary stream 
file?   Then call http_header() to determine if it's MIME encoded or 
not, and it it's MIME encoded, run the stream file through a MIME 
decoder (which would have to be written.) Ultimately, the MIME decoder 
would get the SOAP message, and you could run it through 
http_parse_xml_string() or http_parse_xml_stmf().  If it's not MIME 
encoded, of course, you could run the XML through http_parse_xml_stmf() 
to begin with.

Does that make sense, or have you a better way?
