Loading a list of filtered files

Since I discovered the "powerfullness" of resource and resource collection in 
Ant, I have been able all sort of manipulation on files whithout to have 
tempory files. Until.

I would like to have in one ant property some infos extracted from sevral ivy 
files. Basically I would want to write this:

<loadresource property="@{property}">
    <concat>
        <fileset dir="${fetchdir}" includes="ivy-*.xml">
            <filterchain>
                <tokenfilter>
                    <filetokenizer />
                    <replaceregex pattern="^.*&lt;dependencies&gt;
(.*)&lt;/dependencies&gt;.*$$" replace="&lt;!-- ${module.name} 
dependencies --&gt;\1" flags="si" />
                </tokenfilter>
            </filterchain>
        </fileset>
    </concat>
</loadresource>

Unfortunaltely I cannot apply a filterchain on a fileset.

Maybe there are some other way to do that with resources ?
Or should I use copy and have some temporary files ?

ha, thanks, obviously... I was too focus on some requirement I actually 
dropped.
I wanted to have the name of the file being filtered added as a header of each 
extracted part of the ivy.xml (see some residue of my attempt in the regexp 
as ${module.name}), which I quickly realized it was not feasable.

thanks both of you for your quick replies.

Any reason you can't move the filterchain to the level of loadresource
or concat rather than the indiviual files?

Why don't you apply the filterchain to the concat?  -Matt
