Question

I have a large String and I need to extract String value from it. String value is located between delimiters

category = '

and

';

This is my regex, but I need to avoid outputing delimiters.

String productCategory = Regex.Match(html, @"category = '(.*?)';").Value;

This is the exampe
category = 'Video Cards';

and I need to extract
Video Cards

What you can use is the lookahead and lookbehind operators, so you end up with something like:

string pattern = @"(?<=category = ').*(?=';)";
string productCategory = Regex.Match(html, pattern ).Value;

It’s also worth mentioning that parsing HTML with regexes is a bad idea. You should use an HTML parser to parse HTML.
