occurred. You have to free the string yourself
MatchInfo.fetchNamed
string fetchNamed(string name)Retrieves the text matching the capturing parentheses named name.
If name is a valid sub pattern name but it didn't match anything (e.g. sub pattern "X", matching "b" against "(?P<X>a)?b") then an empty string is returned.
The string is fetched from the string passed to the match function, so you cannot call this function after freeing the string.
Parameters
name | name of the subexpression |
Returns
The matched substring, or null if an error
