[privoxy-users] [3.0.16] Either/or doesn't work as planned

[Gilles <cod...@fr...>]

Hello

I'd like to remove the following sections from a web page:

============
<div class="some-common-label-item1">
blah, blah
</div>

<div class="some-common-label-item2">
blah, blah
</div>

<div class="some-common-label-item3">
blah, blah
</div>
============

So I tried the following regex, but Privoxy doesn't seem to match:
============
s|<div class="some-common-label-(item1|item2|item3)">.+?</div>||sg
============

I tried "debug 64" in Privoxy's config.txt, but it doesn't help: It
says 

"Re-Filter: Filter myfilter has empty joblist. Nothing to do."

Am I using the wrong regex?

Thank you.
