php - send and receive xml documents
<p>I am trying to get a xml document back from the webserver that also supports php.
It's something similar to what the traditional web services do but i want to achieve it in php. Is this even possible?</p>

<p>To be more specific about my needs - 
I want to send a xml document as a request to the server, have PHP do some processing on it and send me back an xml document as a response.</p>

<p>Thanks in advance.</p>
