Read a file line by line and do something for each line

[Felix Dorner <FD...@zed.com>]

Hey,

I'm trying to figure out a way how to read a text file line by line.
Then for each read line I'd like to invoke a macro with that line's contents as an argument. I can't find a better whay than using ant-contribs math+var tasks to count the number of lines read so far. With that I can use <headfilter> to just read the next line. Any other possibilities?

Thanks,
Felix

Yes this works too, apart from my natural dislikes against for. :-)
I'll include a <fixcrlf> filter and meditate into happiness..:

not tested

<loadfile property="src" srcFile="..."/>
<ac:for param="line" list="${src}" delimiter="${line.separator}">
  <sequential>
    <mymacro line="@{line}"/>
  </sequential>
</ac:for>
