If any one from list then
I'm not sure exactly how to write something and am looking for suggestions. A break command for <for> would work (obviously I'm ok with antcontrib as well), but I don't think antcontrib has one.
Say I have a property ${myProp} that contains a comma delimited list, such as "a,w,x,z"
I need to do something based on a subset of those values such as:
if myprop contains element a b c or d
do something...
endif
Is there a simple way to do this? I can think of clumsy ways to do this with regex, but nothing that would make me warm and fuzzy inside...
Thanks,
Eric

Very nice Francis, Thanks! I like this MUCH better.

Another solution, which is more clean, I think. It makes use of
ant-contrib's <foreach>.
With a little exercise, it can be easily generalized to n lists.
The <trycatch> would then be in the doit target, and fail at the first match.
<property name="outerlist" value="a,b,c"/>
<property name="innerlist" value="c,d,e"/>
<target name="doit">
<foreach list="${outerlist}" param="outer" target="do-inner"
inheritall="true"/>
</target>
<target name="do-inner">
<for list="${innerlist}" param="inner">
<sequential>
<if>
<equals arg1="${outer}" arg2="@{inner}"/>
<then>
<sequential>
<echo message="Found match for ${outer}"/>
</sequential>
</then>
</if>
</sequential>
</for>
</target>

This is a solution.
Note that if you want to stop at the first match, then you can
surround the inner for with ant-contrib's <trycatch>, and do what is
needed in the <catch> block.
<property name="outerlist" value="a,b,c"/>
<property name="innerlist" value="c,d,e"/>
<target name="doit">
<for list="${outerlist}" param="outer">
<sequential>
<for list="${innerlist}" param="inner">
<sequential>
<if>
<equals arg1="@{outer}" arg2="@{inner}"/>
<then>
<sequential>
<echo message="Found match for @{outer}"/>
</sequential>
</then>
</if>
</sequential>
</for>
</sequential>
</for>
</target>

OK, so here's how I did it. It works at least... Can anyone think of a better way (I think it's kind of ugly)?

The only think I can come up with is to write a macrodef that is passed a propertyName and a value to be search if it is contained within:
1) Take the list and add a , to the beginning and , to the end
2) Do a regex on ",${searchString},"
If it's there, the item is contained within the list, set a property to "true"...

Excellent point.
Delimiting the items in the list may be necessary. Unfortunately, there is not a containsregexp condition to help with separating the values from the delimiters and boundaries.
Scriptcondition might be a better alternative if you have the bsf.jar and a supported language

The problem is that if you want "foo" and the list is "foobar, baz",
the condition will match.
This is not an easy problem, admittedly. It could be done with two
imbricated <foreach> statements, but that would be an O(n^2)
algorithm. It may, or may not, be a problem, depending on the problem
size.

I think the condition task is what you are after.
<condition>
<or>
<contains string="${myprop}" substring="foo" />
<contains string="${myprop}" substring="foo2" />
