Re^2: Regex - backreferencing multiple matches in one group.

A couple minor suggestions:
Nesting is not needed.
The "\s+.*" at the end does nothing.

/\!(\S+?)             #tablename
 \[(.*?)\]            #table variables
 (?:\[(.*?)\])?
 (?:\[(.*?)\])?
 (?:\[(.*?)\])?
/x

Nesting is not needed, but more clearly indicates the up-to-4. The +.* I grant you, but the \s does do something. -- Online Fortune Cookie Search	[reply]
