Hi,
this mailing list is about pcre library development, not general regular expression questions. Reddit is the right place for those tricky questions:

I try to answer your question though. Since the number of "string" tags are unknown, I would convert this in multiple steps.
- First, I would convert the initial tag, which looks like "string" +
s/((?:^|[^+ ]) *)("[^"]++") *\+/$1CONCAT($2,+/g
- Second, I would convert the +"string"+ parts
s/\+ *("[^"]++") *(?=\+)/, $1/g
- Third, convert the terminator +"strings" with a similar pattern.
Of course depending on the input you could create more complex patterns to fit your needs.
Regards,
Zoltan
