I need regular expression for HTML comment which contains any word

Question

I want to remove HTML comments from my page, below is the format of comment

<!-- saved from url=(0116)file://D:\Documents and Settings\213039755\Local Settings\Temporary Internet Files\OLK5\abc.htm -->

I want regex for HTML comments which contains "Saved" word.

Currently I am using

Regex.Replace(content, "(?<=\\<!--\\s*save\\s*-->)", "sss");

Wrapping the entire regex into a `(?<= )` group won't do anything more than give you trouble. — Unihedron, Jul 15 '14 at 13:12
Yes, [`(?<= )` is a bookbehind group, it asserts position after your match, then replaces a null position.](http://stackoverflow.com/q/22937618) See the answer below, which does what you need correctly. — Unihedron, Jul 15 '14 at 13:16
Your second `\\s*` will match only zero-or-more whitespace, not letters etc. — Hans Keﬆing, Jul 15 '14 at 13:18

This should do it:

String result = Regex.Replace(content, @"<!-- saved[^>]*>", String.Empty);

I also tested and verified the regex before posting (using this tool http://regexhero.net/tester/) – Bill Jul 15 '14 at 13:28
Yes Its not working and when I am using Regex.Replace(content, "", ""); it is removing all comments – Pramod Gupta Jul 15 '14 at 13:29
