Thanks for the quick reply, Hans.

I'll give a fuller description of what I'm trying to do.

I want a Textmate command that inserts into a LaTeX document a \label  
tag whose shape depends on the value for "ch:nn" . ("ch:nn" will be in  
a \label{ch:nn} tag at the top of the document, and will store the  
number of the chapter that the file is.) The label's shape will be  
"\label{exnn:}", where "nn" is the number found in the \label{ch:nn}  
tag at the top of the file and "\label{ex:}" if there is no  
\label{ch:nn} tag at the top of the document. Once the "\label{ex:}"  
or "\label{exnn:}" tag is inserted into the file, I want the cursor to  
be placed right after the colon.

I'm not fluent in regex, although the documentation is clear enough  
for me to hobble through it. But Ruby, or the like, is a steeper climb  
for me. So, it's the do-a-search-and-print- the-results part of the  
process that I'm stymied by.

Thanks again
