This code handles a response from an RSS feed. It organizes and appends to content. If there's a video embeded then separate it from the rest of the content. I would like a review mainly on performance/efficiency but I'm open to any other suggestions as well. That star selector is really nagging me but I don't know of a better way to iterate over all the contained elements.
function getFeed(url, element, callback) {
$.getJSON("https://ajax.googleapis.com/ajax/services/feed/load?v=1.0&callback=?&q="+encodeURIComponent(url), function(response) {
var content = "",
$element = $(element);
for (var i = 0; i < response.responseData.feed.entries.length; i++) {
content = content + response.responseData.feed.entries[i].content; //Join all the feed entries
}
$element.find(".content").html(content).addClass($element.find("embed").length? "withVideo" : "");
$element.find("*").each(function() {
var $this = $(this);
$this.removeAttr("style width align"); //Reset all the crap that comes with the response
if ($this.is("embed")) {
$element.append("<div class='video'></div>");
$this.attr("width", 640).attr("height", 360).parent().appendTo(element + " .video");
};
});
if (typeof callback === 'function') {
callback();
};
});
}
This is then called like so:
getFeed("http://www.kent.k12.wa.us/site/RSS.aspx?PageID=3854", "#TechExpo", optionalCallback);
Here's what a response might look like
<div width="500" style="whatever"><p>Some text blah blah blah.</p>
<p align="right">Some more text</p>
</div>
<div><h2>Video Title</h2>
