Conditional help
Hi all,
I'm new to using Ant and need a little help with an Task I am working on?
In one part of it I need to check if a string does notexist in a certain
file and if it doesn't then I want to add it.
I looked through the manual/web and couldn't find any way of doing it.
Pseudo code:
...
<if>
<isfalse>
<contained in file file="${somefile}" value="${somestring}" />
<then>
<replace file="${src}/index.html">
<replacefilter token="@mytoken@"
value="@mytoken@${somestring}"/>
</replace>
</then>
</isfalse>
</if>
...
Any help greatly appreciated

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
<replace>
<!-- 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="${searchstring}"/>
</fileset>
<!-- if no file remains, 'replace' will do nothing -->
<replacefilter token="@mytoken@" value="@mytoken@${somestring}"/>
</replace>
