delete text from beginning to a specified ending string

[elim]

I have many files need to be modified by removing some heading text and tailing text (the heading text is given by its ending string and the tailing text is given by its starting string)

I hope UEStudio can do that but I don't know how.

Thnks for any help

This is not a regular expression search and replace issue because a regex can't do that. But you can do that with following method - copied from help of UltraEdit/UEStudio - page for Find command:

To select all text between the cursor position and the search target, hold down the SHIFT key at the time the search is started with the Find Next button.

This special search with selection can be also recorded into a macro.
