How to remove latex tags using regex?

问题

I have to remove the bugging unnecessary tags in a document like:

{\sffamily FOOBARFOOOBAR
FOOBAR
FOO \bf{FOOBAR}
FOOBAR
}

into

FOOBARFOOOBAR
FOOBAR
FOO \bf{FOOBAR}
FOOBAR

I used to be able to do this with html tags like

{\sffamily \d } replacing with \1

but i cannot make it work with tex tags..

Anyone any advices?

回答1:

I can give you a regex for your example - you weren't far off with your initial attempt - but I'm not sure it'll help with your overall problem.

Find:

\{\\sffamily ((?:.*\r*\n*)*?)\}

Replace:

\1

WARNING: You will run into problems if the tags you're replacing are nested. But, I don't think there's going to be a way around that using regex without some serious headaches. You would be better off with a small script here.

Use detex, which strips TeX from a source file.
