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=3D"searchRegexp" value=3D"six.*"/>
    <pathconvert property=3D"selected" pathsep=3D"${line.separator}">
        <fileset dir=3D".">
            <scriptselector language=3D"javascript" setbeans=3D"true">
                self.setSelected( filename.match(searchRegexp) !=3D null =
);
            </scriptselector>
        </fileset>
    </pathconvert>
    <echo>Selected files for ${search.regexp}</echo>
    <echo>${selected}</echo>
</project>
