Wildcards within the "Match Attribute Value" field for creating new raise event on tag rule

Hi,

I would like to rewrite "src" attributes inside img-tags. The point is, that there are some links pointing to an inaccessible domain name. The idea is to replace for ex. "http://abc.com/image.jpg" with "http://def.com/image.jpg". That's why I would like to add a wildcard like "http://abc.com/*" to the "Match Attribute Value" field inside the "Create New Raise Event on Tag Rule" form, to include all directories.

Is that possible?

Thanks in advance, best regards
