Hi,

i'm still a newbie to ruby, maybe there's a more
elegant solution, you need jruby available for ant

http://dist.codehaus.org/jruby/jruby-bin-0.9.1.tar.gz


given test.txt =3D

abcd
xyz
what
why
Rebuild All: 1 failed, 0 skipped
new world
Rebuild All: 0 failed, 0 skipped
techno
Rebuild All: 1 failed, 0 skipped
Rebuild All: 10 failed, 0 Skipped


quick hack =3D

<target name=3D"depends">
        <script language=3D"ruby">
        <![CDATA[
            counterfailed=3D0;
            counterskipped=3D0;
            File.open("Y:/test.txt", "r").each do |line|
                if line =3D~ /(\d{1,2}).+(\d{1,2})/
                    counterfailed +=3D $1.to_i
                    counterskipped +=3D $2.to_i
                end
            end
            puts 'Summary :'=20
            puts 'Failed =3D=3D ' +counterfailed.to_s
            puts 'Skipped =3D=3D ' +counterskipped.to_s
           =20
            $project.setNewProperty "failed", counterfailed.to_s
            $project.setNewProperty "skipped", counterskipped.to_s
           =20

          ]]>
          </script>
	</target>
=20
	<target name=3D"main" depends=3D"depends">    =20
     <echo>$${failed} =3D=3D ${failed}</echo>  =20
     <echo>$${skipped} =3D=3D ${skipped}</echo>  =20
	</target>

depends:
   [script] Summary :
   [script] Failed =3D=3D 12
   [script] Skipped =3D=3D 0
main:
     [echo] ${failed} =3D=3D 12
     [echo] ${skipped} =3D=3D 0
BUILD SUCCESSFUL
Total time: 1 second

The regular expression \d{1,2} matches one or max 2 occurences of a
digit,
hope you don't get such a lot of failed rebuilds ;-)

If needed you can match 1 or 2 or 3 digits with \d{1,3} and so on ...

=20

Thanks: the regular expression works now, which is progress.=20
Unfortunately I'm getting all of the concatenated text, not just the=20
matching text. If I use replace:
<filterchain>
  <!--<tokenfilter><filetokenizer />-->
    <containsregex flags=3D"isg"
      pattern=3D"${summary.regex}"
      replace=3D"SUMMARYTABLE"
      byline=3D"false" <!-- implies filetokenizer -->
      />
    <!-- </tokenfilter>-->
</filterchain>

I end up getting something like:
[concat] <html>
[concat] <head>
[concat] <title>summary</title>
[concat] <link rel=3D"stylesheet" href=3D"summary.css" =
type=3D"text/css">
[concat] </head>
[concat] <body>
[concat] <a name=3D"overview"></a>
[concat] <center>
[concat] SUMMARYTABLE
[concat] </center>
[concat] ...more HTML here...
[concat] </html>

I'm assuming it's because the file is just one big token - but if I use=20
a line tokenizer, will I be able to match regular expressions over=20
multiple lines?

Thanks for the help.
