<section1 topic='Introduction'>
|
|
<p>This document defines a module for &xep0062; that provides an XPath matching condition for packet filtering.</p>
|
|
|
|
<p>This module operates in the "http://jabber.org/protocol/filter/xpath" namespace.</p>
|
|
</section1>
|
|
|
|
<section1 topic='Conditions'>
|
|
<p>This module defines the fullowing conditions:</p>
|
|
|
|
<ul>
|
|
<li><xpath/> - true if the XPath expression contained in the CDATA of this element, when applied to the packet, returns one or more nodes.</li>
|
|
</ul>
|
|
|
|
<example caption='Matches all messages with that have a subject element'><![CDATA[
|
|
<xpath xmlns='http://jabber.org/protocol/filter/xpath'>/message/subject</xpath>
|
|
]]></example>
|
|
|
|
<example caption='Matches all presence packets that have an x:delay stamp'><![CDATA[
|
|
<xpath xmlns='http://jabber.org/protocol/filter/xpath'>/presence/x[namespace-uri()=='jabber:x:delay']</xpath>
