Ant - how to print file name from fileset in a filterchain

I want to prepend each matching line with file name where it's found.

I tried ${file.name}, but it does not work.

<concat destFile="report.xml">
    <filterchain>
        <linecontainsregexp>
            <regexp pattern="somePattern"/>
        </linecontainsregexp>
        <prefixlines prefix="${file.name}"/>
    </filterchain>
    <fileset dir="${pathToDirectory}" erroronmissingdir="false">
        <include name="**"/>
    </fileset>
</concat>

The following code uses the <for> task from the third-party Ant-Contrib library. <for> iterates over every file in a fileset.

<for param="file.path">
  <path>
    <fileset dir="${pathToDirectory}" erroronmissingdir="false">
      <include name="**"/>
    </fileset>
  </path>
  <sequential>
    <concat destFile="report.xml" append="true">
      <path>
        <pathelement location="@{file.path}"/>
      </path>
      <filterchain>
        <linecontainsregexp>
          <regexp pattern="somePattern"/>
        </linecontainsregexp>
        <prefixlines prefix="@{file.path}:"/>
      </filterchain>
    </concat>
  </sequential>
</for>

To use Ant-Contrib, download ant-contrib-1.0b3-bin.zip, extract ant-contrib-1.0b3.jar from it, and follow the instructions on how to install Ant-Contrib.
