Question

I am very weak with Regex and need help. Input looks like the following:

<span> 10/28 &nbsp;&nbsp;Currency:&nbsp;USD

Desired output is 10/28.

I need to get all text between the <span> and “Currency:” that are numbers, a “/” character, or a “:” character. No spaces.

Can you help? Thanks.

Updated: What you’re describing is three parts.

What we do want is one or more characters that are digits, forward slash, and :: [0-9/:]* (the asterisk means “zero or more instances”). Surrounded by:

• <span>(optional stuff we don't want) is represented as: <span>[^0-9/:]*
• (optional stuff we don't want)Currency is: [^0-9/:]*Currency

(The ^ means “not”) – so this will essentially match any number of characters which is not the bits we want, including things like  

In c#:

string pattern = @"<span>[^0-9/:]*(?<value>[0-9/:]*)[^0-9/:]*Currency";
Match match = Regex.Match(input, pattern, RegexOptions.SingleLine | RegexOptions.IgnoreCase);
string output = match.Groups["value"].Value;
