Your code does more than simple substitution, it deletes everything not
in the parens.  Maybe that's what you want.

maybe perldoc perlrequick to start.
perldoc perlintro (header Regular Expressions)
perldoc perlfaq6
perldoc perlretut

The parens enclose only one character, one that is not a double-quote. 
The plus is looking for one or more copies of that character?

You need something more like:

s/(href=")(.*?)"/$1$2&sid=blah"/
