Question

I have to check if these two url match a pattern (or 2, to be more accurate). If so, I’d like to extract some portion of data.

1) /selector/en/any-string-chain-you-want.aspx?FamiId=32

Then I need to extract “en” and “32” into variables. To me the regex expression should like roughly something like /selector/{0}/any-string-chain-you-want.aspx?FamiId={1}

2) /selector/en/F/32/any-string-chain-you-want.html

where en and 32 must be assigned into variables. So:
/selector/{0}/F/{1}/any-string-chain-you-want.html

{0}: 2 letters language code such as en, fr, nl, es,…
{1}: family id integers (2 or 3 numbers) such as 12, 38, 124, etc but not 1212

Any idea on how to achieve it?

Thanks in advance,

Roland

Answer 1

This is the regex:

/selector/([a-z]{2})/.+?\.aspx\?FamiId=([0-9]+)

Code:

var regex = new Regex(@"/selector/([a-z]{2})/.+?\.aspx\?FamiId=([0-9]+)");
var test = "/selector/en/any-string-chain-you-want.aspx?FamiId=32";

foreach (Match match in regex.Matches(test))
{
    var lang = match.Groups[1].Value;
    var id = Convert.ToInt32(match.Groups[2].Value);

    Console.WriteLine("lang: {0}, id: {1}", lang, id);
}

Regex for second case: /selector/([a-z]{2})/F/([0-9]+)/.+?\.html (code doesn’t change)
