Why is my Regex subpattern only working when matching recursively?

Question

Link to demo of the Regex. I don't understand why (?P=name) causes the pattern to not match. I can't use recursion because I'm using the pattern in C#.

Your issue is C# Regex does not support subroutines, which is what (?P(DEFINE) creates. You also can't use a backreference, as the Row values aren't equal, you just have to insert the subroutine inline and repeat it:

^ +<tr class="clickable" data-id="(?<AccountID>[^"]+)" data-jobid=\"(?<JobID>[^\"]+)\"(?:(?:<\/td)?>[^>]+>)(?<InvoiceID>[^<]+)(?:(?:<\/td)?>[^>]+>)(?<Date>[^ ]+)\n +(?:(?:<\/td)?>[^>]+>)(?<Status>[^<]+)(?:(?:<\/td)?>[^>]+>)(?<Type>[^<]+)(?:(?:<\/td)?>[^>]+>)(?<Total>[^<]+)(?:(?:<\/td)?>[^>]+>)(?<Balance>[^<]+)(?:(?:<\/td)?>[^>]+>)(?<Paid>[^<]+)(?:(?:<\/td)?>[^>]+>)(?<Technician>[^<]+)(?:(?:<\/td)?>[^>]+>)
