Ok, big examples for all three.
But I have NOT tested these ideas :-)


a) using AntContrib=B4s <foreach>

AntContrib is available at [1].
If you have a list (like your String) you can use

<foreach target=3D"doCopy" param=3D"todir" list=3D"${list}"/>

<target name=3D"doCopy">
    <copy file=3D"${file}" todir=3D"${todir}"/>
</target>


You can define the target directories using <dirset>s.

<foreach target=3D"doCopy" param=3D"todir">
    <path>
        <dirset dir=3D"c:\test\web" includes=3D"**/chk/**"/>
    </path>
</foreach>

<target name=3D"doCopy">
    <copy file=3D"${file}" todir=3D"${todir}"/>
</target>




b) using AntContrib=B4s <for>

Simply the same as with <foreach> but without the need of a new target.
The problem is that this task is not described in the manual (of
AntContrib).
So you have to look into the source (and understand the most of =
that)...

<for param=3D"todir" list=3D"${list}">
    <sequential>
        <copy file=3D"${file}" todir=3D"${todir}"/>
    </sequential>
</for>

or the way using <dirset>


<for param=3D"todir">
    <path>
        <dirset dir=3D"c:\test\web" includes=3D"**/chk/**"/>
    </path>
    <sequential>
        <copy file=3D"${file}" todir=3D"${todir}"/>
    </sequential>
</for>

But <for> requires the newest Ant version (not released yet), so sais =
the
javadoc
comment at the beginning of the For.java [2]:
 * Task definition for the for task.  This is based on
 * the foreach task but takes a sequential element
 * instead of a target and only works for ant >=3D 1.6Beta3

You can download the latest binary from [3].


c) using <script>

This example uses JavaScript, therefore you need the dependend =
libraries
described
in manual [4].

If you use a list, you have to split that inside your loop. For that =
you can
use the
StringTokenizer class.

<property name=3D"file" value=3D"the-copied-file"/>
<property name=3D"list" value=3D"dir1,dir2"/>
<script language=3D"javascript"> <![CDATA[
    list =3D project.getProperty("list");  // the name of the property =
as
argument
    file =3D project.getProperty("file"); =20
    tokenizer =3D new StringTokenizer(list);
    copy =3D project.createTask("copy");
    copy.setFile(new java.io.File(file));
    while (tokenizer.hasMoreTokens()) {
        todir =3D tokenizer.nextToken();
        copy.setTodir(new java.io.File(todir));
        copy.perform();
    }
]]></script>


If you uses <dirset> you can iterate over that


<property name=3D"file" value=3D"the-copied-file"/>
<dirset id=3D"todirs" dir=3D"c:\test\web" includes=3D"**/chk/**"/>
<script language=3D"javascript"> <![CDATA[
    file =3D project.getProperty("file"); =20
    copy =3D project.createTask("copy");
    copy.setFile(new java.io.File(file));
    ds =3D todirs.getDirectoryScanner(project);  // use the id for =
accessing
the dirset
    targetDirs =3D =3D ds.getIncludedFiles();
    for (i=3D0; i<targetDirs.length; i++) {
        todir =3D tokenizer.nextToken();
        copy.setTodir(new java.io.File(todir));
        copy.perform();
    }
]]></script>


Because you=B4re using Ant=B4s API, a look into their description [5] =
would be
good.
And the manual for <script> [6] has some hints, too.




Like I said, these examples are not tested. So they may contain some =
errors.
But you should be able
to find them and correct them :-)
