[opencms-dev] custom filter for xmlcontent

[Wolfgang Winzer]

Hi everybody,

I am using the taglibrary to display some userdefined xmlcontent:

<cms:contentload collector="allInFolder" 
param="${opencms.folder}news/newsitem_${number}.xml|7|3" editable="true">
         <div class="title"><cms:contentshow element="Title" /></div>
</cms:contentload>

now I'd like to show only those items, that fulfill the condition 
<cms:property name="keyword"> equals <cms:contentshow element="keyword">
where the property is of course taken from the current page.

Any suggenstion how to do that? I can't evaluate the result from the 
tags in a scriplet afaik.
Thx for your help
Wolfgang
