{title:Pattern matching for {cmd:ds}}

{p 4 4 2}
Patterns are used with the {cmd:has()} and {cmd:not()} options to {cmd:ds}.
A pattern consists of the expected text with the addition of the characters
{cmd:*} and {cmd:?}.  {cmd:*} indicates one or more characters go here
and {cmd:?} indicates exactly one character goes here.
