Can sed perform editing operations ONLY in the matched region?
Hi:

Let's suppose I want to replace all the | by > ONLY when | is between []. Usually (and it works) I would do something like

sed -e 's/\(\[[^|]*\)|\([^[]*\]\)/\1>\2/g'

where I have to "save" some portions of the matched region and use them with the \n metacharacter. I was wondering if I could execute something like that

SelectTheFragmentsThat Match(/\[[^]]*\]) and then execute in those pieces s/|/>/g and left the rest of the line unchanged

So, a lot of times I want to perform only editing operations in the region matched, and I want lo left thje rest of the line unchanged. Is that possible?

Thanks a lot

Original text

AAAA [one|1] BBBB | CCCCC [two|2] DDDDD

desired result

AAAA [one>1] BBBB | CCCCC [two>2] DDDDD

only the | between [] are changed. I know how to perform the chage (see my post) but I would like to know if it exists a more "intuitive" way in sed.

Thanks a lot
