Question

I have following function into to get the text between tags but it is returing tag as well so anyone tell me whtat is wrong in regex expression.

String.prototype.getTextBetweenTags = function (tagname) {

var pattern = "<" + tagname + " ?.*>(.*)</" + tagname + ">";  
return this.match(pattern)[0];

}

return <title>hello</title>

should return just Hello

Answer 1

The first element of the result is the entire string. Element 1 is the contents of the first capturing group.

Try this:

return this.match(pattern)[1];

Also, don’t use regex to parse HTML. There are hundreds of ways that your regular expression could break.
