Operator Scope of Action:
Operator First Added:
Captures a sequence of non-whitespace characters ('tokens'), the matched token string is passed to targetAttribute. The stream is not advanced and any chained parsing continues from the same point. Punctuation (notably @) is part of a token but *not* part of a word.
If the targetAttribute is omitted the Stream is advanced to the end so processing ceases.
The attribute given for targetAttribute can be a quoted literal string, e.g.
("Text") for $Text. Or it can be an unquoted variable/loopVariable, e.g.
(vString) for a variable 'vString'.
