I want to ping automatically to pingomatic, when ever i update my blog, as it is done by the wordpress. Pingomatic uses the XMLRPC, but I don't know how it works. Can someone help me.
Seems quite easy at first sight. The form there is a plain HTML form with method=get and I don't see any XMLRPC code around. I'd say you just fill in the form once, click to submit and then copy the resulting URL from the address bar into a PHP http_get() or fopen(). The result page says "Bookmark this page and come back to it later to automatically re-ping", so I'm pretty sure a plain GET request is enough and there is no other magic involved.
