I’m building a RSS feed of my website using jquery and the link element

  • 0

I’m building a RSS feed of my website using jquery and the link element keeps returning blank. I do not have a problem with the javascript solution i built on my own but the jquery seems to hate the link element.

below is the jquery code:

function loadData(xml, ifid) {
        var htmlStr;
        var iframeToWrite = document.getElementById(ifid);

        htmlStr = "<html><body>"
        var items = $(xml).find("channel item").each(function () {
            var $article = $(this);
            var title = $article.find("title").text();
            var description = $article.find("description").text();
            var link = $article.find("link").text();
            var pubDate = $article.find("pubDate").text();

            htmlStr += "<div class='Rssitem'>\n";
            htmlStr += "\t<h3><a href='" + link + "' target='_blank' >" +
               title + "</a></h3>\n";
            htmlStr += "\t<p>" + description + "</p>\n";
            htmlStr += "\t<h6>" + pubDate + "</h6>\n";
            htmlStr += "</div>\n"
        });

        htmlStr += "</body></hmtl>";
        iframeToWrite.contentDocument.write(htmlStr);

    }

below is a sample xml i edited from the npr stream I get:

    You have to parse your xml string into a xml document first jQuery.parseXML().
    To quote the documentation:

    jQuery.parseXML uses the native parsing function of the browser to
    create a valid XML Document. This document can then be passed to
    jQuery to create a typical jQuery object that can be traversed and
    manipulated.

    If you don’t use parseXML and wrap a jQuery selector around it, jQuery may not be able to interpet all the nodes properly.

    In your example the <link> tags are not inerpeted correctly and the </link> closing tags have been removed without parsing, hence you cannot query the link text correctly.
    You can confirm that if you do a console.log($(this)) and check the content in the console output. You can see the <link> then text but the closing </link> is missing.

    However, when parsing your xml first to a document object you can now wrap a jQuery selector around it and access all nodes reliably. Off course, assuming the inital XML string was valid XML.

    DEMO – Using parseXml on your xml string and querying it after

    Applying this to your code would look similar to this:

    htmlStr = "<html><body>";

// Parse the XML to a document object and then wrap it into a jQuery selector
var $xml = $($.parseXML(xml));

var items = $xml.find("channel item").each(function() {
    var $article = $(this);
     //..... rest of your code as is
