Pulling custom node/field from wordpress rss feed

Thu, 03 Oct 2013 04:45:42 -0700 

Hello,

I've inherited some code at work from a colleague who has left. It's 
javascript (see below) that displays the contents of a wordpress events 
feed on a plain html page, via the google api.

There's a custom node/field/thing that I had to add to the feed so we can 
ouptut the event date rather than the published date - 
<eventDate>...</eventDate>.

After extensive googling, I now know pulling in the custom 
node/field/whatever-it's-called from the rss requires google to output it 
in xml or mixed format. I also know I need to use getElementsByTagName or 
getElementsByTagNameNS to target <eventDate>. However the best I can do is 
to get it to output "undefined" or "[object NodeList]" as text.

The line I've tried adding is in bold below, just below the commented out 
published date lines we are currently using - obviously that's not ideal 
for events! 

If anyone could explain what I need to do, it would be most appreciated. 
I'm really not au fait with this kind of thing coming from a design 
background.

function loadEventsFeeds(feedUrl, numEntries) {
var feed = new google.feeds.Feed(feedUrl);
feed.setResultFormat(google.feeds.Feed.MIXED_FORMAT);
feed.setNumEntries(numEntries);
feed.load(function(result) {
if (!result.error) { 
var container = document.getElementById("events-feed");
 // Handle the featured item
var entry = result.feed.entries[0];
 if (entry == null) {container.innerHTML = "<p>There are currently no items 
in this category. However we are constantly updating our news and events so 
please check back again soon.</p>";}
 var newsBlockOuterEl = document.createElement("div");
newsBlockOuterEl.setAttribute("class", "col_title_content float_left");
var newsBlockImgWrapper = document.createElement("div");
newsBlockImgWrapper.setAttribute("class", "span-7 col float_left");
newsBlockOuterEl.appendChild(newsBlockImgWrapper);
 var newsBlockTextOuterWrapper = document.createElement("div");
newsBlockTextOuterWrapper.setAttribute("class", "span-7 last col");
//newsBlockTextOuterWrapper.setAttribute("class", "span-14 last col");
var newsBlockTitleWrapper = document.createElement("div");
newsBlockTitleWrapper.setAttribute("class", "theme_colour cufon_me 
font_size_18 float_left");
newsBlockTitleWrapper.innerHTML = "<a 
href='"+entry.link+"'>"+entry.title+"</a>";
newsBlockTextOuterWrapper.appendChild(newsBlockTitleWrapper);
newsBlockTextOuterWrapper.innerHTML += "<br class='clear' />";
 var date = document.createElement("p");
date.setAttribute("class", "small");
//date.innerHTML = "Published on ";
//date.appendChild(document.createTextNode(formatDate(new 
Date(entry.publishedDate))));
*date.innerHTML = date.getElementsByTagName("eventDate");*
newsBlockTextOuterWrapper.appendChild(date);
 var newsBlockContent = document.createElement("p");
newsBlockContent.setAttribute("class", "noImage");
newsBlockContent.innerHTML += entry.content;
newsBlockTextOuterWrapper.appendChild(newsBlockContent);
 // Find and assign image
var imgEls = newsBlockContent.getElementsByTagName("IMG");
if (imgEls.length == 0) {
imgEls[0] = document.createElement("img");
imgEls[0].setAttribute("width", "215");
imgEls[0].setAttribute("height", "150");
imgEls[0].setAttribute("alt", entry.title);
imgEls[0].setAttribute("src", 
"http://assets.bournemouth.ac.uk/aqua-retrofit/images/news-default-medium.jpg";);
}
imgEls[0].setAttribute("class", "margin_right_10px news_img_large");
newsBlockImgWrapper.appendChild(imgEls[0]);
newsBlockOuterEl.appendChild(newsBlockTextOuterWrapper);
 container.appendChild(newsBlockOuterEl);
// End handle featured item 
 // Handle the other items
for (var i = 1; i < result.feed.entries.length; i++) {
var entry = result.feed.entries[i];
var newsBlockOuterEl = document.createElement("div");
var newsBlockOuterClass = "span-7 col";
if (!(i % 2))  newsBlockOuterClass += " last";
newsBlockOuterEl.setAttribute("class", newsBlockOuterClass);
 var newsBlockContent = document.createElement("p");
newsBlockContent.setAttribute("class", "noImage");
newsBlockContent.innerHTML += entry.content;
 // Find and assign image
//var imgEls = newsBlockContent.getElementsByTagName("IMG");
//if (imgEls.length == 0) {
//imgEls[0] = document.createElement("img");
//imgEls[0].setAttribute("width", "77");
//imgEls[0].setAttribute("height", "55");
//imgEls[0].setAttribute("alt", entry.title);
//imgEls[0].setAttribute("src", 
"http://assets.bournemouth.ac.uk/aqua-retrofit/images/news-default-small.jpg";);
//}
//imgEls[0].setAttribute("class", "margin_right_10px news_img_small");
 var newsBlockTitleWrapper = document.createElement("div");
newsBlockTitleWrapper.setAttribute("class", "theme_colour cufon_me 
font_size_18 float_left");
//newsBlockTitleWrapper.appendChild(imgEls[0]);
newsBlockTitleWrapper.innerHTML += "<a 
href='"+entry.link+"'>"+entry.title+"</a>";
newsBlockOuterEl.appendChild(newsBlockTitleWrapper);
newsBlockOuterEl.innerHTML += "<br class='clear' />";
var date = document.createElement("p");
date.setAttribute("class", "small");
date.innerHTML = "Published on ";
date.appendChild(document.createTextNode(formatDate(new 
Date(entry.publishedDate))));
newsBlockOuterEl.appendChild(date); 
newsBlockOuterEl.appendChild(newsBlockContent);

container.appendChild(newsBlockOuterEl);
}
  
}
}); 
}

Thanks
