Hello...
Is there a way, using a find/replace program and regular expressions, that I can turn this sample text...

I'm not sure if regular expressions are powerful enough to change the date information, but I would assume that I can use the enclosure tag to create the guid (replace <enclosure url="*" length="" type="audio/mp3"/> with <enclosure url="*" length="" type="audio/mp3"/>{}e<guid>*</guid>).
Unfortunately, that isn't working. I've been reading about regex, but I'm just not getting it, for this purpose (replace this and this, but nothing between). Honestly, I haven't been getting a lot of it.
Hehehe...
I would also assume that you can delete any line that start with such and such, but I haven't figure that out, either.
Thanks for the help.
