Hi,
A quick breakdown...
/(['"])(((''|"")|[^'"])*?)\1(\s|$)/g
^^^^^^
1 ^^^^^^^^^^^^^^^^
2
^^
3
1) This is picking up either a single or double quote
2) This is scoping up any quotes pairs, and is being carefull not
to match quotes on thier own.
3) In a regex \1, \2 etc.. will match the same sequence of characters
matched
earlier in the same-numbered pair of parentheses, in this case, it means
that were making sure the opening and closing quotes are the same by
mathching
that same character as in part 1.
Explaining it like this has made me spot a problem. The regex you really
want is
m/(['"])(((''|"")|[^\1])*?)\1(\s|$)/g
This way our 'scoping up' part matches any paired quotes or anything other
than
our closing quote.
The following test data wouldn't have worked...
' data11 '' dat"a12' 'data13'

Please do, my mistake above shows you why you shouldn't reinvent this stuff
if you can
get away with it. :-)
