<section1 topic='Introduction'>
<p>This document defines a module for &xep0062; that provides some basic conditions and actions to perform common packet filtering tasks.</p>
<p>This module operates in the "http://jabber.org/protocol/filter/basic" namespace.</p>
</section1>
<section1 topic='Conditions'>
<p>This module defines the fullowing conditions:</p>
<ul>
<li>&lt;message/> - true if the packet is a &lt;message/> packet.</li>
<li>&lt;presence/> - true if the packet is a &lt;presence/> packet.</li>
<li>&lt;iq/> - true if the packet is a &lt;iq/> packet. If this element contains CDATA, then it must match the namespace of the first element inside the packet (typically &lt;query/>) in order to be true.</li>
<li>&lt;to/> - true when the CDATA of this element matches the "to" attribute of the packet.</li>
<li>&lt;from/> - true when the CDATA of this element matches the "from" attribute of the packet.</li>
<li>&lt;type/> - true when the CDATA of this element matches the "type" attribute of the packet.</li>
</ul>
<example caption='Matches all presence packets'><![CDATA[
<presence xmlns='http://jabber.org/protocol/filter/basic'/>
]]></example>
<example caption='Matches all jabber:iq:version IQ packets'><![CDATA[
<iq xmlns='http://jabber.org/protocol/filter/basic'>jabber:iq:version</iq>
]]></example>
<example caption='Matches all packets from user@company.com'><![CDATA[
<from xmlns='http://jabber.org/protocol/filter/basic'>user@company.com</from>
]]></example>
</section1>
<section1 topic='Actions'>
<p>This module defines the fullowing actions:</p>
<ul>
<li>&lt;drop/> - drops the packet</li>
<li>&lt;bounce/> - bounces the packet with the error specified in the "code" attribute of this element.</li>
<li>&lt;redirect/> - redirects the packet to the JID specified in the CDATA of this element.</li>
<li>&lt;copy/> - sends a copy of the packet to the JID specified in the CDATA of this element, while giving the original packet to the user.</li>
</ul>
<example caption='Pretend that we don&apos;t exist'><![CDATA[
<bounce xmlns='http://jabber.org/protocol/filter/basic' code='404'/>
]]></example>
<example caption='Send a copy to our home account'><![CDATA[
<copy xmlns='http://jabber.org/protocol/filter/basic'>me@home.com</copy>
