Hrm, it probably isn't since advanced regexs are still black magic to
me. The "." was supposed to match any character, including a newline
(with the s flag), the * to say match 0-n of them and the ? to say be
lazy, match as little as possible (so that I don't pull in
<table>...</table><table>...</table> in one match).
I just tried [^<], but it doesn't seem to work - I think because of such
things as "<table><tr>...</tr></table>" - the opening bracket of <tr>
conflicts. I tried [.<>]*? to make sure that the "regex.body" part
was matching the brackets, but that didn't work either.
Also, <table class="summary"> was wrong - <table class="summary"(.*?)>
is a little better since the tables can have more than the class
attribute (in fact, all of them do). But after changing that I'm
matching the entire document - <html> through to </html>. That might
just be because I'm using filetokenizer - if I make one match within
filetokenizer, do I end up getting the entire document? If so, how do I
get only the matching text?
Regex is now: <table class="summary".*?>.*?</table>
Thanks for the help, I appreciate it.

Subject: containsregex and concat
I've been trying to use a regular expression and the concat task to
pull summary tables (<table class="summary">...</table>) out of a set
of test reports. The reports are all HTML files sitting in
${report.path}. The task works fine up until I start trying to select
output from it with <containsregex>. Is there something wrong with my
regular expression? Is there an easier way to do this? Any help would
be appreciated.
The code is:
====================
<target name="summary"> <!-- make a report summary -->
<property name="summary.start" value="<table
class="summary">" />
<property name="summary.body" value=".*?" /> <!-- enable "s" for
newline matches -->
<property name="summary.end" value="</table>" />
<property name="summary.regex"
value="${summary.start}${summary.body}${summary.end}" />
<echo>${summary.regex}</echo>
<concat>
<header>HEADER</header>
<fileset dir="${report.path}"
includes="*.html"
excludes="${summary.file}" />
<filterchain>
<tokenfilter>
<filetokenizer />
<containsregex flags="is"
pattern="${summary.regex}" />
</tokenfilter>
</filterchain>
<footer>FOOTER</footer>
</concat>
</target>
====================
The regular expression echoes as:
====================
<table class="summary">.*?</table>
====================
I've done some testing of the expression at
http://www.fileformat.info/tool/regex.htm, and it seems to work there.
