Such a useless code dump! The problem is pretty simple, but you did not ask any question. What's the problem? Just do it.

If you want to remove the whole select element with it's content, then you can do it with regex only if some constraints are met: no nested element of the same name (select in this case).

Try this:

C#

string pattern = @"<select\b[\s\S]*?</select>";

Thanks.... string pattern = @"<select\b[\s\S]*?"; worked for me :) now just need to get the value and the text out the middle

Andreas Gieriet 24-Oct-12 18:27pm

Hello 1castle1,
Out of the middle of what?
Example: input = ..., expected output = ...?
Cheers

and it doesn't remove the option tags as it was asked for in question. :doh:

Waseem Fastian 6-Feb-12 12:23pm

this regex will remove the select tag in the html and option tag is inside the select tag.So option tag will be automatically deleted.

Andreas Gieriet 6-Feb-12 13:57pm

This regex will not remove the whole select element with it's content. Did something went lost while pasting it into the solution?

Cheers

This regex has removed all the select content.I have used this in my project and it did it. Cheers

Andreas Gieriet 7-Feb-12 15:03pm

Yeah. Now it's better. Before the whole second select part went lost up to the ].
Now, I agree. This would work fine, though, it's a bit an overkill. You use (...) which wil store the matched string. Use (?:...) instead. And if you want to make sure that a word is not part of a larger word, you may use the word-boundary anchor \b. Combining all that results in my solution #3.

But as you said: your's work as well.
