Converting a Python regular expression to C#

Question

I have this regular expression in python:

'<input type="hidden" name="GALX" value="(?P<galx>[a-zA-Z0-9_]+)">'

I want an equivalent regular expression string for C#. This string gives a parsing error in c#. Thanks in advance.

I've tried this:

Regex rc = new Regex("<input type=\"hidden\" name=\"GALX\" value=\"(?P<galx>[a-zA-Z0-9_]+)\">");

It gives me this error:

parsing \"<input type=\"hidden\" name=\"GALX\" value=\"(?P<galx>[a-zA-Z0-9_]+)\">\" - Unrecognized grouping construct.

If you remove the "P" so that the "<" is right after the "?" it parses fine.

yes, compiled fine...but I wonder if it's the same expression as in the above python string? – Uzair Farooq Dec 31 '11 at 06:44

@UzairFarooq - Just beware that working with regex groups in C# are significantly different than those used in Python. – M.Babcock Dec 31 '11 at 06:50
