I'm actually working on a rather complex module to handle this type of thing. I guess I gave the impression that a sound entry was the only type of data object in the file. In fact it is a self referential nested tree with many types of objects...

:)

I could, however, slurp a line at a time until the line was ^\s*Sound$ then make sure the next line was correct, check if the name matched (and steal the white space). Finally I'd check the next line and either add a priority line or update it. I could write each line right back out to the output file as I go.

That's a much better approach and much less prone to bugs (and it would work around the reg-ex memory leak in 5.8.2).

Thanks
