Additional script to raid?

[Krewniak]

Hello. I was looking for anything on whole Google, and nothing, so I decided to create this thread.
If anyone have any information how to do this, please, share his knowledge.

I have created small raid with rats:

raids.xml
<?xml version="1.0" encoding="UTF-8"?>
<raids>
	<raid name="Rats" file="Rats.xml" interval2="1" margin="0" reftype="single" ref="no" >
	</raid>
</raids>

Rats.xml
<?xml version="1.0" encoding="UTF-8"?>
<raid>
    <announce delay="1000" type="Blue" message=" DUM DUM DUM DUM PLAGA DUM DUM DUM DUM " /> 
    <singlespawn delay="5000" name="Rat" x="1025" y="1021" z="7"/>
	<singlespawn delay="5000" name="Rat" x="1025" y="1019" z="7"/>
	<singlespawn delay="5000" name="Rat" x="1026" y="1020" z="7"/>
	<singlespawn delay="5000" name="Rat" x="1024" y="1020" z="7"/>
	<singlespawn delay="4500" name="Cave Rat" ref="yes" x="1025" y="1020" z="7"/>
	<effect delay="4250" name="bigclouds" x="1025" y="1020" z="7"/>
</raid>

Everything works fine, but I need to create something better. If there is no player nearby, these rats will just stand like freezed, maybe walk a few squares somewhere.
I thought about creating invisible mobs, which would be attacked by them, and create by this a way to the city, for example.
I found also something like: otland.net/f83/best-raid-system-d-83525/ but it doesn't work for me.
I get error:

[24/03/2013 22:48:44] [Error - Raid::loadFromXml] Could not load raid file (data/raids/Rats.lua).
[24/03/2013 22:48:44] Line: 1, Info: Start tag expected, '<' not found

When trying to execute something like:

<raid name="Rats" file="Rats.lua" interval2="1" margin="0" reftype="single" ref="no" >
</raid>

So, anyone have an idea how to use functions on raids? And what is doing, and how to use this magic fucntion:

function onRaid()
doBroadcastMessage("Broadcast from a raid script!")
return true
end

Change

<?xml version="1.0" encoding="UTF-8"?>
<raids>
    <raid name="Rats" file="Rats.xml" interval2="1" margin="0" reftype="single" ref="no" >
    </raid>
</raids>

To

<?xml version="1.0" encoding="UTF-8"?>
<raids>
    <raid name="Rats" file="Rats.xml" interval2="1" margin="0" reftype="single" ref="no"/>
</raids>

Maybe it'll work.
