Parsing XML with namespace (such as slash:comments)

parse.js

el[0].getElementsByTagNameNS('http://purl.org/rss/1.0/modules/slash/', 'comments')[0].innerHTML;

// or a fuller example

$.get('/blogfeed.php', function (data) {
    var count = 1;
    $(data).find("item").each(function () {
        var el = $(this);
	// ...
        // how many comments
        // textContent must be used instead of innerHTML because webkit returns a NodeList instead of HTMLCollection, and NodeList
        // apparently doesn't have innertHTML as a property of the element
        var commentCount = parseInt(el[0].getElementsByTagNameNS('http://purl.org/rss/1.0/modules/slash/', 'comments')[0].textContent);
	// ...
    });
});
