Operator Scope of Action:
Operator First Added:
Stores the source text string up to, but not including, the designated literal matchString into the designated targetAttribute, and returns the string that follows matchString. Note that matchString is not a regular expression and can only be a literal string.
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'.
