you could use a regular expression to find every appearance of things between '{' and '}', and then replace them with "nothing". Note that I don't know Komodo Edit, but I'm guessing it is capable of using regular expressions to search / replace text. Sou you'll have to find out how.
the expression could be like this:
{[\w\s:;#]*}
If you don't know regular expressions, here it is a short explanation:
- { and } match the { and }
- [] is the group of characters you will look into the brackets, and here goes whatever you need to select.
- \w matches leters and numbers, and the underscore
- \s matches white spaces (spaces, tabs, etc)
- : ; # - directly matches those symbols
just add any other symbols that you may find between the { }, I may forgot some of them.
However, I highly recommend learning regular expressions, they are a powerful tool to achieve exactly what you need.
A nice playground for regexs can be found here, and over here I've put you the regex I suggest for you to play around with it.
One last word: If you need more help with regular expressions, you could go to stackoverflow instead of here. (perhaps they'll even migrate your post, but I'm answering you here).
good luck!
