Subject: Re: string scan question

Here is a simple test case

s = <VariableValue>\nXXX\n</VariableValue>\n\n<VariableValue>
\n<Choice> Administrative Support - Supervisors<Choice>\n</
VariableValue>\n\n"

for the VariableValue tag, there should be 2 array elements  \nXXX
\n    AND   \n<Choice> Administrative Support - Supervisors<Choice>\n

s.scan(/<VariableValue>(.+?)</).flatten   returns an empty array
