Parse an HTML string with JS
I searched for a solution but nothing was relevant, so here is my problem:
I want to parse a string which contains HTML text. I want to do it in JavaScript.
I tried this library but it seems that it parses the HTML of my current page, not from a string. Because when I try the code below, it changes the title of my page:
var parser = new HTMLtoDOM("<html><head><title>titleTest</title></head><body><a href='test0'>test01</a><a href='test1'>test02</a><a href='test2'>test03</a></body></html>", document);
My goal is to extract links from an HTML external page that I read just like a string.
Do you know an API to do it?

Create a dummy DOM element and add the string to it. Then, you can manipulate it like any DOM element.
var el = document.createElement( 'html' );
el.innerHTML = "<html><head><title>titleTest</title></head><body><a href='test0'>test01</a><a href='test1'>test02</a><a href='test2'>test03</a></body></html>";
el.getElementsByTagName( 'a' ); // Live NodeList of your anchor elements
Edit: adding a jQuery answer to please the fans!
var el = $( '<div></div>' );
el.html("<html><head><title>titleTest</title></head><body><a href='test0'>test01</a><a href='test1'>test02</a><a href='test2'>test03</a></body></html>");
$('a', el) // All the anchor elements
