Question

Examples using javascript to run a GET on another URL, retrieve the xml returned and look up a specific node?

Answer 1

+1 A:

You can use XMLHttpRequest to make an AJAX call to the url, as long as it's on the same domain (AJAX has same-origin policy). Also, take a look here for some tips on manipulating XML in Javascript.

If you are using jQuery, you can use jQuery.ajax and set the datatype to XML.

If your XML resides on another URL (i.e., not on your domain), then things get trickier. You'll need to use something server-side (like PHP, ASP, or JSP's) that generates a Javascript file that contains the XML (which it grabs from the URL) stored in a string. Then, in your page you'll need a script tag that points to this Javascript file.

Answer 2

+1 A:

Using jQuery it's really easy because you an 'query' the XML document like you would with an X/HTML document.

Let's say you had a simple xml document like this...

<book>
  <title>Catcher in the Rye</title>
  <author>J.D. Salinger</author>
</book>

You can use jQuery to load the document and parse out particular nodes.

<html>
<head>
  <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js"&gt;&lt;/script&gt;
  <script type="text/javascript">
    $(function() {
        $.get("/book.xml", function(responseXml) {
            var xml = $(responseXml);
            var title = $("title", xml).text();
            var author = $("author", xml).text();

            alert(title); // >> Catcher in the Rye
            alert(author); // >> J.D. Salinger
        });
    });
  </script>
</head>
<body>
</body>
</html>

And vivin makes a great point about loading xml from an external domain.
