Using Regular Expressions

[Guest]

I need some help.

This regular expression strips out html tags "<>"
/*Strips the HTML tags from strHTML */
Regex objStripHTML = new Regex("<(.|\n)+?>");

How would I construct a Regular expression to strip out one this code:
<STYLE type='text/css' MEDIA='print'>.MSGLINE {display:none;}
</STYLE>

Thanks

Mike

<\s*style\s+.*?<\s*/style\s*> and set RegexOptions to Ignore Casesensitive

Matthias:

Many, many thanks but I don't understand the syntax!!!
<\s*style\s+.*?<\s*/style\s*>

Can you break this down for me in english?

Also, I did not find a property to ignore case. Can you advise

Hi Mike,

here the detail Syntax

"<" = HTML Tag open

"\s*" = \s means Whitespace and * means no one, one or more, that means
it finds <style, < style, < style ...

"\s+" = one or more Whitespace (+ Syntax) (<style ... = ok , <style ...
= ok, <style... = false)

..*? = To next character which match after the ? ("hello you" and e.*?o
matches ll)

"<\s*style\s*>" = end tag of </style> but with whitespace check, so it
can be < /style>, </style >, < /style >

Regex m1 = Regex.Match(strSource, @"<REGEX>", RegexOptions.IgnoreCase

This means it find for example as regex = h(.*?)o in HELLO the ELLO in
m1.Groups[1].Value.ToString(), but if you have not set the IgnoreCase it
finds nothing, because you need H(.*?)O ... Regex is CaseSensitive until
you say them this.

Hope this helps...

There are a lot of things about Regex. If you are intersted in this
install Perl, because it has one of the strongest Regex Implementation.
And you find alot of sources for regex and perl at google

Mike,

You might want to try the Regex workbench at:

http://www.gotdotnet.com/Community/...mpleGuid=C712F2DF-B026-4D58-8961-4EE2729D7322

If you type in a regex, it can tell you what it means.

Thanks for the tip. But we are still on Framework 1.0.

The tool requires 1.1 framework which I can't install becuase of issue with CMS 2002
do you know if their is a version that will work with 1.0 framework

Thank

Mik
