Can someone help me with the regexp that will match exactly two
quotes(') or no quotes in the string.
If a single quote exists, then will break out.
eg:
aabbcc - Should Match
aa''bb''c''c - Should Match
a''b - Should Match
ab'' - Should Match
aa'bbcc - Should not Match
aa''bb'cc - Should not Match (since there is a single quote)
'aabcc - Should not Match
This does what you have described. It looks for a single quote, preceded
by a character other than a single quote or the start of the string, and
followed by a character other than a single quote or the end of the
string.
if (not /(?:\A|[^'])'(?:\Z|[^'])/) {
print "matches\n"
}
