How can I extract the string "XMLFileName" from the below URL using regular expression

Answer 1

You could do it with split() , pop() and replace() ...

var filename = x.split('\\').pop().replace(/\..+$/, '');

jsFiddle .

You could also use a single regex...

var filename = x.replace(/.*\\|\..*$/g, '');

jsFiddle .

Ensure you escape the \\ in your string literal too.

Answer 2

trivial

/([^\\]+)\.[^\\]+$/

of course you weren't very specific, so while this will work for your particular case, I'm not here to read your mind.

Answer 3

You can use: " [^\\\\]*$ "

but why not using regular javascript functions like indexOf() etc.
