Subject AW: Conditional help
Date Mon, 08 Feb 2010 06:07:09 GMT
Instead of first selecting a file and then checking its content I would do the other order:
1. Select all files which contains the searchstring
2. replace the the tokens

1. is done with a selector: <contains>
2. your <replace> task, but with nested <fileset> from #1

    <!-- use dir,includes,excludes for narrowing all files to a smaller amount -->
    <fileset dir="..." includes="...">
        <!-- checking the content is more expensive than checking names -->
        <contains text="${searchstring}"/>
    <!-- if no file remains, 'replace' will do nothing -->
    <replacefilter token="@mytoken@" value="@mytoken@${somestring}"/>
