Question

I have different option how my GUIDS could be stored as a string line.

1. Accessibility|5102d73a-1b0b-4461-93cd-0c024738c19e
2. 5102d73a-1b0b-4461-93cd-0c024738c19e;#5102d73a-1b0b-4461-93cd-0c024733d52d
3. |;#5102d73a-1b0b-4461-93cd-0c024738c19e;#SharePointTag|5102d73a-1b0b-4461-93cd-0c024733d52d
3. Business pages|;#5102d73a-1b0b-4461-93cd-0c024738cz13;#SharePointTag|5102d73a-1b0b-4461-93cd-0c024733d52d

Could you guys help me to with ideas how could I parse this tags and get List of Guids type in the end? Maybe regular expression could help in such situation?

Looks like you’re playing with Managed metadata, term store ID and term set ID 🙂

Just use a regular regexp (the “p” variable below):

string c1 = "Accessibility|5102d73a-1b0b-4461-93cd-0c024738c19e";
string c2 = "5102d73a-1b0b-4461-93cd-0c024738c19e;#5102d73a-1b0b-4461-93cd-0c024733d52d";
string c3 = "|;#5102d73a-1b0b-4461-93cd-0c024738c19e;#SharePointTag|5102d73a-1b0b-4461-93cd-0c024733d52d";
string c4 = "Business pages|;#5102d73a-1b0b-4461-93cd-0c024738cz13;#SharePointTag|5102d73a-1b0b-4461-93cd-0c024733d52d";
string p = @"([a-zA-Z0-9]{8}[-][a-zA-Z0-9]{4}[-][a-zA-Z0-9]{4}[-][a-zA-Z0-9]{4}[-][a-zA-Z0-9]{12})";

MatchCollection mc;

Console.WriteLine("#1");
mc = Regex.Matches(c1, p);
foreach (var id in mc)
    Console.WriteLine(id);

Console.WriteLine("#2");
mc = Regex.Matches(c2, p);
foreach (var id in mc)
    Console.WriteLine(id);

Console.WriteLine("#3");
mc = Regex.Matches(c3, p);
foreach (var id in mc)
    Console.WriteLine(id);

Console.WriteLine("#4");
mc = Regex.Matches(c4, p);
foreach (var id in mc)
    Console.WriteLine(id);

Wich output:

#1
5102d73a-1b0b-4461-93cd-0c024738c19e
#2
5102d73a-1b0b-4461-93cd-0c024738c19e
5102d73a-1b0b-4461-93cd-0c024733d52d
#3
5102d73a-1b0b-4461-93cd-0c024738c19e
5102d73a-1b0b-4461-93cd-0c024733d52d
#4
