That looks like an iffy way to parse strings :p

Sounds like it should be done at the module level.

If you insist, there's possibly a way to do it with current scripting:
With textedit, write your text to a file and remove the middle. Then use xLabel's !LabelInfoExport and *line*() function(s) on that file to read it back into a variable.

It's ridiculous the things I'm trying these days :)
