RegExp to strip HTML comments

Question

Looking for a regexp sequence of matches and replaces (preferably php but doesn't matter) to change this (the start and end is just random text that needs to be preserved)

IN:

fkdshfks khh fdsfsk <!--g1--><div class='codetop'>CODE: AutoIt</div><div class='geshimain'><!--eg1--><div class="autoit" style="font-family:monospace;"><span class="kw3">msgbox</span></div><!--gc2--><!--bXNnYm94--><!--egc2--><!--g2--></div><!--eg2--> fdsfdskh

to this:

OUT:

fkdshfks khh fdsfsk <div class='codetop'>CODE: AutoIt</div><div class='geshimain'><div class="autoit" style="font-family:monospace;"><span class="kw3">msgbox</span></div></div> fdsfdskh

Thanks

Answer 1

Are you just trying to remove the comments? How about

s/<!--[^>]*-->//g

or the slightly better (suggested by the questioner himself):

<!--(.*?)-->

But remember, HTML is not regular, so using regular expressions to parse it will lead you into a world of hurt when somebody throws bizarre edge cases at it.

Answer 2

Ah I've done it,

<!--(.*?)-->

Answer 3

preg_replace('/<!--(.*)-->/Uis', '', $html)

This PHP code will remove all html comment tags from the $html string.
