Question

I have been given some poorly formatted data and need to pull numbers out of strings. I’m not sure what the best way to do this is. The numbers can be any length.

string a = "557222]]>";
string b = "5100870<br>";

any idea what I can do so I’ll get this:

a = "557222"
b = "5100870"

Thanks

Solution is for c# sorry. Edited the question to have that tag

Answer 1

Not familiar enough with .NET for exact code. Nonetheless, two approaches would be:

• Cast it as an integer. If the non-digit characters are at the end (i.e. 21389abc), this is the easiest.
• If you have intermixed non-digit characters (i.e. 1231a23v) and want to keep every digit, use the regex [^\d] to replace non-digit characters.
