Creating a Google Gadget for a WP feed

This is not an actual problem with WP or even related to WP code as such. However there are a lot of clever people out there who might be able to help.

I’ve been having a go at creating a Google Gadget which reads my feed content and displays it in a module (gadget) within the Google Personalized homepage.

I’ve followed Google’s own suggested code, which works OK for me when the Google blog feed is used, but when I switch it over to my own feed it goes blank.

Google is definitely reading the feed because when I change the gadget code to just point at the feed url it does display it within the box, without any formatting of course.

Google’s suggested code, from:

https://www.google.com/apis/homepage/guide.html

is as follows:
******************************************
<?xml version=”1.0″ encoding=”UTF-8″ ?>
<Module>

<ModulePrefs title=”Google Blog” render_inline=”optional” />
<UserPref name=”post” datatype=”enum” display_name=”Post Number” default_value=”1″>

<EnumValue value=”1″ />
<EnumValue value=”2″ />
<EnumValue value=”3″ />
<EnumValue value=”4″ />
<EnumValue value=”5″ />
<EnumValue value=”6″ />
<EnumValue value=”7″ />
<EnumValue value=”8″ />
<EnumValue value=”9″ />
</UserPref>

<Content type=”html”>
<![CDATA[
<!– load the NXSL library –>
<script src=”https://www.google.com/js/nxsl.1.js&#8221; type=”text/javascript”></script>
<div id=”content___MODULE_ID__”></div>

<script type=”text/javascript”>
_IG_RegisterOnloadHandler(function () {
var url = ‘https://googleblog.blogspot.com/atom.xml&#8217;;
_IG_FetchContent(url, function (response) {
var prefs = new _IG_Prefs(__MODULE_ID__);
var nxsl = xmlParse(”
+ ‘<div select=”/feed/entry[‘ + prefs.getInt(‘post’) + ‘]”>’
+ ‘ <h3 select=”title” content=”.”></h3>’
+ ‘ <div select=”content” content=”.”></div>’
+ ‘</div>’);
nxslProcess(xmlParse(response), nxsl);
var content = xmlText(nxsl);
content = content.replace(/</g, ‘<‘)
.replace(/>/g, ‘>’)
.replace(/&/g, ‘&’)
.replace(/[“]byline-author[“]/g,
‘”byline-author” style=”font-size:84%;color:#666666;”‘);
_gel(‘content___MODULE_ID__’).innerHTML = content;
});
});
</script>

]]>
</Content>
</Module>
