JQuery's ajax function stripping HTML tags from XML

Okay, I'm pulling data from an XML file to populate my elements of my webpage dynamically. My problem is that when I use JQuery .ajax to pull the xml file, it strips my HTML tags.

For example,

Data in XML file:

<transcript><p>Hello, world</p></transcript>

Desired output on webpage: 

<p>Hello, world</p>

Actual output:

Hello World

Here is my code inside of my ajax function:

$(xmlData).find('item').each(function() {
        var n = $(this).find('transcript').text();

I've tried to use JQuery's '.html()' but it returns null. What is the simplest way I can fix this? Preferably without changing too much of what I've already done.

Thanks in advance.

Using text will strip the tags as you experienced. You can instead use the jQuery children method (reference) on the transcript node to get the HTML. Here is a working example: http://jsfiddle.net/gjwyd/

$(document).ready(function() {
    $.ajax({
        type: "POST",
        url: "/echo/xml/",
        dataType: "xml",
        data: {
            xml: "<transcript><p>Hello, world</p></transcript>"
        },
        success: function(xml) {
            var container = $('#content');
            var html = $(xml).find('transcript').children();
            container.html(html);
        }
    });
});​

The key is this line:

var html = $(xml).find('transcript').children();

And being sure to set the dateType as xml.

Issues

When taking HTML from an XML response it may be missing the default styles. For example, a paragraph tag may not have display: block. Resetting the styles may be one way around this issue. A more correct and probably easier way would be to put the HTML content inside of CDATA within the XML as one of the other commenters suggested.

http://jsfiddle.net/tZJQp/

$(document).ready(function() {
    $.ajax({
        type: "POST",
        url: "/echo/xml/",
        dataType: "xml",
        data: {
            xml: "<transcript><![CDATA[<p>Hello, world</p><p>Bye</p>]]></transcript>"
        },
        success: function(xml) {
            var container = $('#content');
            var html = $(xml).find('transcript').text();
            container.html(html);
        }
    });
});

As others note, html won't work on XML.
