regexp

[Ken Ray]

Sorry about that... hit the Send button too soon.

The key to remember in MC (after 2.4.2 where PCRE was added) is the modifier
"(?s)" which means to "treat the entire chunk of text as my string, ignoring
newlines". So if you want to get the chunk from the beginning of the "W" in
"Welcome" to the end ">" in "<!user-name>", you can use this:

-- I have your text snippet in field 1
on mouseUp
  local tStart,tEnd
  get matchChunk(fld 1,"(?s)(Welcome.*?<!user-name>)",tStart,tEnd)

  select char tStart to tEnd of fld 1
end mouseUp

Hope this helps!
