This template uses Lua :
The Template:Str_number/trim
It takes a string as parameter, and returns the string trimmed to the beginning number if non-numeric text does not appear before the first number.

Analysis and searching
{ { str startswith } } { { str endswith } } Check if a string starts or ends with a given string. { { str find } } { { strfind short } } Returns the numerical location of a given string in a string. { { in string } } Returns optional string when given string is not found { { str count } } Count the number of occurrences of a pattern within a string.
