url pattern is like HYPERLINK "http://www.roseindia.net/hibernate/examples/criteria" http://www.roseindia.net/hibernate/examples/criteria
In pattern = /(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!-\/]))?/;
/../(forward slashes) is used to quote your regular expression.
() is used to group the content.
| is used for or condition
\/ backslash consider / as a literal .
\w+ for one or more alphanumeric value.
{0,1} shows the range of content having length between 0 to 1.
* matches the preceding character zero or more time.
[..] matches any letter enclosed with in.
+ shows that preceding character come 1 or more times.
. Shows that \ will treat . as a literal.
$ is used for ending the string.
test() method takes one argument and check that to the pattern.
