*XML-RPC* or _XML remote procedure call_ is a [[xml]]-based protocol that uses HTTP to transmit procedure calls.

XML-RPC is a very simple protocol and was created by [[Dave Winer]] in 1995, in conjunction with [[Microsoft]].

Microsoft and others later extended XML-RPC into a more complex protocol called [[SOAP]].

A typical XML-RPC message looks like this:

<code>

<pre>

<?xml version="1.0"?>

<methodCall>

<methodName>example.getName</methodName>

<params>

<param>

<value><a>42</a></value>

</param>

</params>

</methodCall>

</pre>
