Plugin problem

[vsforums]

I got in plugin code:

$content = "<if condition=\"THIS_SCRIPT != 'adv_index'\">something</if>";

$vbulletin->templatecache['headinclude'] = $vbulletin->templatecache['headinclude'] . fetch_template('my_template');
eval('$vbulletin->templatecache[\'headinclude\']');

and in my_template I have:
$content

and unfortunately in page source I see those ifs....
I should see only "something" if I'm on adv_index without those ifs.
<if condition="THIS_SCRIPT != 'adv_index'">something</if>

Anyone any idea how to do that ? I cant place those ifs in template...
Is this doable? How?
