Using regular expressions to select files when using ant copy task

[Jack Blan]

Hi,

I have 'src' folder and a 'dest' folder.  The 'src' folder has the following files:
1) ans_key.tif
2) arrow.tif
3) eqn_y=x+1.tif
4) re teach.tif
5) ab+cd.tif

I want to copy all files that conform to a naming convention to 'dest' folder.  The rules are simple: only allowed characters in file names are a-z, A-Z, 0-9, dash(-), underscore(_) and period(.).  Which means, I want only files 1 and 2 to be copied over to 'dest'.  For this purpose, I wrote the following build.xml:

<project name="name of project" default="copy_graphics" basedir=".">
    <target name="copy_graphics" description="Copy Graphics">
        <copy overwrite="true" todir="dest">
            <fileset dir="src" includes="**/*.tif">
            <containsregexp expression="^[a-zA-Z0-9\._-]+$"/>
            </fileset>
        </copy>
    </target>
</project>

But it didn't work.  What's more confusing is except for file 2 (arrow.tif ), all others get copied.  

I read in one of the forums that <containsregexp> looks in the content rather than the filename.  So I tried playing around various combinations of:
            <fileset dir="src">
            <filename name="**/^[a-zA-Z0-9\._-]+\.tif$"/>
            </fileset>

That didn't work either.  Can anybody please help?

Thanks!

I've played around with this, and containsregexp does select files
based upon content and not the name of the file. There might be a way
around this by using the <scriptselector>. Unfortunately, I don't know
JavaScript or Apache BSF well enough to figure out how this might
work.

Does anyone know Javascript well enough to help out?

An example of a <scriptselector> based upon the length of the name is
shown here:
