Converting an Ant fileset to multiple apply args

Question

I have some files:

dir/foo.txt
dir/bar.txt
dir/foobar.txt

In an Ant apply task, I want to pass the list of files as arguments:

Here's an example illustrating the use of the pathconvert task.

The converted path is passed to the executable using <arg line />.

This assumes no spaces in the paths of your *.txt files.

<target name="atask">
    <fileset dir="dir" id="myTxts">
        <include name="*.txt" />
    </fileset>
    <pathconvert property="cmdTxts" refid="myTxts" pathsep=" " />

    <apply executable="${cmd}" parallel="false" verbose="true">
        <arg value="-in" />
        <srcfile />
        <arg line="${cmdTxts}" />

        <fileset dir="${list.dir}" includes="*.list" />
    </apply>
</target>

If you might encounter spaces this should do: as above, but change (hopefully obvious which lines) to:

    <pathconvert property="cmdTxts" refid="myTxts" pathsep="' '" />

and

        <arg line="'${cmdTxts}'"/>
