My humblest apologies--I did not state my problem clearly. I want to find a
set of files whose contents (not the file name) includes a string based on
the name of the file containing it. That is, for each file path/xxx.yyy, I
want to know if the file contains a string like this:
"See doc page at path/xxx.html".
So <containsregexp> seemed the most promising, as discussed, but it uses
only a "constant" regexp, not a parameterized regexp.

Ok, I had a look into the source of <containsregexp>
org.apache.tools.ant.types.selectors.ContainsRegexpSelector.
It checks the 'content' of the file ...
- directories are always selected
- files are selected its content matches the regexp expression
I'll update the manual to make this more clear.
After that I think that you want to select files which 'names' match the regexp.
The <filename> selector supports simple pattern matching like '*' but no real
regexps.
I havent found a builtin one, but with BSF+Java4 or Java6 you could use a
scripted selector.
<project>
<property name="searchRegexp" value="six.*"/>
<pathconvert property="selected" pathsep="${line.separator}">
<fileset dir=".">
<scriptselector language="javascript" setbeans="true">
self.setSelected( filename.match(searchRegexp) != null );
</scriptselector>
</fileset>
</pathconvert>
<echo>Selected files for ${search.regexp}</echo>
<echo>${selected}</echo>
</project>

Yes I have tried "containsregexp". As far as I could tell,
there is no way
to parameterize the regexp within the fileset, so that does not work.
