How to pick id from this embed code?

---

Here is a javascript solution:

var result = inputString.match(/id="([^"]*)/);
alert(result[1]);

This searches for the string id=" and then match everything that is not a ", this part is put into a capturing group becasue of the brackets around it, you find this then in result[1].

be careful if there are more than one id=" in your string.

Here is a working example: JSFiddle (I removed the script part from the end of the example string)

try this regex

(?<=id=")[a-z\_0-9]+

It will give you the value of id from your embedded code
