%matches
The expression %matches represents a list that contains all available back-references to regular expression matches. This is equivalent to the list of back reference values [$0;$1;$2….$N], where N is the count of available regular expression matches.
If $MyString is "I do not like green eggs and ham.", then for this code:
if($MyString.contains("like (((green) (eggs)) and ham)")){
$MyList = %matches;
};$MyList now holds 5 back-references:
- $0:
like green eggs and ham - $1
green eggs and ham - $2
green eggs - $3
green - $4
eggs
Query back-references are discussed in fuller detail here.
