In this particular instance, could you try and help me out with a regexp 
that will work? I'm so lost sometimes when it comes to these things. 
Particularely. if I have a string that containts "1234 1234 [% bla [% 
xyz %] abc [% asdf %] baz %] foo [% bar %] bla bla", how do I isolate 
the outer and inner tag in a smart way? I was thinking about storing the 
position in the string, so that I could later insert the variable at 
that point. If I try to just match on /\[\% (.*?) \%\]/ $1 will containt 
"bla [% xyz", and that's not quite what I want. At the same time, if I 
omit the question-mark, it will suddenly trap "bla [% xyz %] abc [% asdf 
%] baz %] foo [% bar", which is not quite what I want either... As I 
said, the logic of regexp sometimes eludes me...
