Question

So I have a string like this

string = "<user>username 1<notes>Notes of User 1</notes></user> <user>username 2<notes>Notes of User 2</notes></user>"

How could I parse the string in Javascript or JQuery to pull out the “Notes” of either user 1 or user 2.

So I’ll have a variable like this:

variable = user;

printout notes of user.

Answer 1

to identify the notes of user1 or user2 you need to change your xml a bit

string = "<user>username 1<notes id='user1'>Notes of User 1</notes></user> <user>username 2<notes>Notes of User 2</notes></user>"

notice that i added id=user1

alert($(string).find("notes[id='user1']").text());

EDIT after the -1 🙁

No, jQuery selectors do not parse XML.
This may appear to work at times, but it’s invalid and browser-dependent.

So, here is the parseXML way:

 xmlDoc = $.parseXML(string),
    $xml = $(xmlDoc),
    $title = $xml.find("notes[id='user1']").text();

alert($title);
