strMatches is a Condition→ which checks that a string matches the provided regular expression.

if strMatches %SomeString% Regex
  # Match found
end

Groups

If you wish to extract groups/values from a regex you can use the return value. While the primary return value is the condition result, suitable for an if→ statement, the extended results contain the typical regex matching groups.

Each group is stored as %Return:Groups:#% where the # is the matched group, 0 being the entire string.

set %DateLike% 02.12.2004
if strMatches %DateLike% ^([0-9]+)\.([0-9]+).*$
  Notice %Return:Group:0%
  Notice %Return:Group:1%
  Notice %Return:Group:2%
end

Notice that we start the regular expression with ^ meaning to match the beginning of the string. Since we are doing a full match anyways this isn't strictly necessary. However, since a starting open parenthesis indicates a function call in TestPlan, it is a good way to avoid that here.
