find <img> tag inside text string

I have an xml document (from a feed), which I'm extracting values from:

$(feed_data).find("item").each(function() {
    if(count < 3) {
    //Pull attributes out of the current item. $(this) is the current item.
        var title = $(this).find("title").text();
        var link = $(this).find("link").text();
        var description = $(this).find("description").text();

Now inside "description" i need to get the img element, but this is causing me some problems. "descripttion" is a regular string element and it seems i can't call the ".find()" method on this, so what do i do?

I have tried calling .find():

var img = $(this).find("description").find("img");

But it's a no go. The img is wrapped in a span, but I can't get to this either. Any suggestions? I'd prefer 开发者_如何学编程to avoid substrings and regex solutions, but I'm at a loss.

I've also tried turning the "description" string into an xml object like so:

var parser = new DOMParser();
var desc = parser.parseFromString(test,'text/xml'); 

$(desc).find("img").each(function() {
    alert("something here");
});

But that doesn't work either. It seems like it would, but I get a "document not well formed" error.

Try enclosing the contents of the description tag in a dummy div, that seemed to work better for me, and allowed jQuery's .find() to work as expected.

e.g.

$(feed_data).find("item").each(function() {
    if(count < 3) {
        //Pull attributes out of the current item. $(this) is the current item.
        var title = $(this).find("title").text();
        var link = $(this).find("link").text();
        var description = '<div>' + $(this).find("description").text() + '</div>';
        var image = $(description).find('img');

Hi and thanks for the prompt replies. I gave GregL the tick, as I'm sure his solution would have worked, as the principle is the same as what I ended up with. My solution looks like this:

    $(feed_data).find("item").each(function() {
        if(count < 3) {
            //Pull attributes out of the current item. $(this) is the current item.
            var title = $(this).find("title").text();
            var link = $(this).find("link").text();
            var description = $(this).find("description").text();

            var thumbnail = "";
            var temp_container = $("<div></div>");
            temp_container.html(description);
            thumbnail = temp_container.find("img:first").attr("src");

So wrap the string in a div, and then use "find()" to get the first img element. I now have the image source, which can be used as needed.

maybe you should try to convert the description text to html tag and then try to traverse it via jquery

$('<div/>').html($(this).find("description").text()).find('img')
