xmlrpc posting with Xpostulate

Okay...I've started to hack up the xmlrpc functions.
First, I had to replace all "<" and ">" in html tags in a post with"&lt;" and "&gt;",
and then, I have basically just handwritten out a relevant xml file.
Which looks like this:

<?xml version="1.0"?><methodCall><methodName>LJ.XMLRPC.postevent</methodName><params><param><value><struct><member><name>username</name><value><string>tonytraductor</string></value></member><member><name>password</name><value><string>XXXXXXXX</string></value></member><member><name>subject</name><value><string>xmlrpc posting</string></value></member><member><name>lineendings</name><value><string>pc</string><value></member><member><name>year</name><value><int>2010</int></value></member><member><name>mon</name><value><int>04</int></value></member><member><name>day</name><value><int>06</int></value></member><member><name>hour</name><value><int>10</int></value></member><member><name>min</name><value><int>46</int></value></member><member><name>prop_current_location</name><value><string>127.0.0.1</string></value></member><member><name>propr_current_mood</name><value><string>focused</string></value></member><member><name>prop_taglist</name><value><string>xmlrpc, xpostulate, wordpress, livejournal, dreamwidth, insanejournal</string></value></member><member><name>prop_currentmusic</name><value><string>none</string></value></member><member><name>userjournal</name><value><string>which journal?</string></value></member><member><name>event</name><value><string>Okay...I've started to hack up the xmlrpc functions.

</string></value></member></struct></value></param></params></methodCall>


What I haven't done is tried to send such a file to a server, yet...
I'm not sure if the posting method has to be different from a flat post, in terms of simply sending this file as the post data...
More work...
But, hey, I'm working on it!
