Re: RegExp adaptation hell...

I'm sure there is some sweet way to do it, but why don't you just do it in two passes. The first one just put www.mydomain.org in the regex and the second one replace all {h1} links and include the image. This will be slow, but if you don't get any better ideas... <speedfreak@chello.be> wrote in message news:3E9F6618.8A9C3F1@chello.be... > For a CMS I need to implement a feature which adds a > 'link-points-offsite' image to all external hyperlinks (don't ask).
