Extract url from string

To extract URL from a string you can use below javascript functions:

function parseUrl1(data) {
var e=/^((http|ftp):\/)?\/?([^:\/\s]+)((\/\w+)*\/)([\w\-\.]+\.[^#?\s]+)(#[\w\-]+)?$/;

if (data.match(e)) {
    return  {url: RegExp['$&'],
            protocol: RegExp.$2,
            host:RegExp.$3,
            path:RegExp.$4,
            file:RegExp.$6,
            hash:RegExp.$7};
}
else {
    return  {url:"", protocol:"",host:"",path:"",file:"",hash:""};
}
}



function parseUrl2(data) { var e=/((http|ftp):\/)?\/?([^:\/\s]+)((\/\w+)*\/)([\w-.]+.[^#?\s]+)(#[\w-]+)?/;

if (data.match(e)) {
    return  {url: RegExp['$&'],
            protocol: RegExp.$2,
            host:RegExp.$3,
            path:RegExp.$4,
            file:RegExp.$6,
            hash:RegExp.$7};
}
else {
    return  {url:"", protocol:"",host:"",path:"",file:"",hash:""};
}
}
