Hi every one,

    I have a basic regular expressions question.
It goes like this: How do I extract a sequence of
@-delimited characters from a text?

Example: @{1}.*?@{1}
Will give:
123456789abcdefhghij
When applied to the following text:
@123456789abcdefghij@987654321stuvwxyz@

However I am trying to build a regular expression
for the more complex case that will also handle the
escape character for @ which the double @@. Consequently
I need to know how to extract

123456789@@abcdefhghij

from

@123456789@@abcdefghij@987654321@@stuvwxyz@

using regular expressions.

Thanks
