What about creating a <loadfile> task with a few <filtersets>?
Loadfile places the content of a file into a property. The
<filterchain> acts on the contents of that file. I load the file
input.sql into the property ${sql.line}. But, I add three filter
chains. The first filters out all lines except the one I am looking
for. The second transforms that line by removing the beginning and
trailing ends of the line, leaving only the middle you want. I also
had to add one more to strip out the linefeed on the end of the line.
<project name="test" default="test" basedir=".">
<target name="test">
<loadfile
srcfile="input.sql"
property="sql.line">
<filterchain>
<linecontainsregexp>
<regexp pattern="where keyp_clientid in .*--Second Wave"/>
</linecontainsregexp>
<tokenfilter>
<filetokenizer/>
<replaceregex pattern="^where keyp_clientid in
.*(\(.*\)).*$" replace="\1"/>
</tokenfilter>
<striplinebreaks/>
</filterchain>
</loadfile>
<echo message="Line is "${sql.line}""/>
</target>
</project>
What's nice about this is that it depends upon no operating specific
<exec> tasks, or outside ant tasks.
