how do i extract info contained on
{...}
[...]
(...)
/*...*/
and <...>
using regex?
i mean: everything that's not between and of course including brackets must go.

Probably not the most elegant way...
Code: Select all
$a = <<<>>>
This [text1] is...
This (text2) is...
This {text3} is...
This <text4> is...
This /*text5*/ is...
>>>;
$b = regexreplace($a, ".*([[<({]|/\*)(.*?)([]>)}]|\*/).*", "$2");
text $b;

thanks much highend.
i've tried hard but can't let it work: is there a way to preserve all respective brackets?

i've tried hard
And what did you try exactly?
is there a way to preserve all respective brackets?
Elaborate more...

the attempts we made messing up the regex.
i need to have
[text1]
(text2)
{text3}
<text4>
instead of
text1
text2
text3
text4

The regex itself doesn't need to be modified to accomplish that...
You just have to change the replacement from $2 to $1$2$3...
