Extracting delimited name values for multiple names ( List Lookup)

Hi

I wouldn't  mind some thoughts on my approach

On my form I have captured multiple selected names from lookup lists

5;#John Does;#6;Jane Doe

If I use the regex operation in my workflow

will this work so I can output to a collection var colNames - I want to be write each to the Workflow history

Do I sill need the For Each loop & Extract Value from Collection to pick say the first name or can I can I simply use Extract Item Collection Action

If I use For Each can I store each in a separate var for use in Send Mail?
