I'd just use <property name="files_path" refid="fileset"> and then
check if property "files_path" is greater than zero.
<fileset dir="WebInfra/Source" id="fileset" includes="**/*">
<containsregexp expression="dg" />
</fileset>
<property name="files_path" refid="fileset">
<condition property="prop_from_condition">
<equals arg1="${files_path}" arg2=""/>
</condition>
That I believe works in 1.6.5. I took a quick look at a few other ways
using selectors, but I don't think those work with 1.6.5.
