Re: sed html tags
snip Hi, I have the string span 111 /span span /span And i wish to use sed to strip *only* the span tag and its contents... is this possible ? I'm trying this expression, but it doesn't work... sed 's/span [^\(/span\)]+\/span//g' file is there anything like it ? I would like to obtain I hope someone can help, thank you, siran If you haven't yet solved the above problem, give the following a try: sed 's/\(span .*.*\/span\)\(.*\)\(span .*.*\/span\)/\2/' regards, joseph snip ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: sed html tags
yes, it does work perfectly with the example I gave... the actual file is some like ... span 111 span www no /span /span span yyy /span span yyy /span ... your command only returns ]# sed 's/\(span .*.*\/span\)\(.*\)\(span .*.*\/span\)/\2/' file I wish to rip all span xxx .* /span and obtain ... span yyy /span span yyy /span... i think sed should be able to do it, but the operator [ ^ ( ) ]* is not behaving as i think it would... perl does it alright, though : s thanks, siran On Thu, Aug 28, 2008 at 12:49 PM, Joseph Olatt [EMAIL PROTECTED] wrote: snip Hi, I have the string span 111 /span span /span And i wish to use sed to strip *only* the span tag and its contents... is this possible ?

If you wish to rip out all span xxx .* /span then the output would
be:
If that is what you want, then try the following:
sed 's/span [a-z]*[ 0-9a-z]*\/span//g; s/\/span//g'
But if Perl is already doing the job for you, I think this can be put to
rest.

... span yyy /span span yyy /span...
i think sed should be able to do it, but the operator [ ^ ( ) ]* is
not behaving as i think it would... perl does it alright, though : s

Re: sed html tags
Well, thanks, Yuri ! That worked much better than all that i had done ! But i have the problem that I don't know what characters to expect... accents, ñ, etc... So i really need a get everything between the span and the first /span... Regarding perl, it is perfect ! thanks ! The ? is critical ! Is it what makes what makes the .* non greedy ?
