Re: trouble with regular expressions

my code s/(\;do.*)(\<\/iframe\>\'\)\;)/sss/; matches only first 4 symbols...

The regex inside your substitution matches the whole string, not "only first 4 symbols", whatever you mean by "symbol".

So, what do you want to do?

my old code matches the ;doc and gives result such as `ssscument.write('<iframe ...shortened...</iframe>');` No, it does not: `use 5.010; use strict; use warnings; $_ = q[;document.write('<iframe src="any url" scrolling="auto" framebo +rder="no" align="center" height="15" width="15"></iframe>');]; s/(\;do.)(\<\/iframe\>\'\)\;)/sss/; say __END__ sss` [download] Anyway, it's easier if you use a different delimiter so that you don't have to escape the forward slashes: `s{(\;do.)(</iframe>'\);)}{//eof};` [download] Perl 6 - the future is here, just unevenly distributed	[reply] [d/l] [select]
