maxNumberOfPostsPerLabel = 100;
maxNumberOfLabels = 3;


function listEntries10(json) {
var ul = document.createElement('ul');
var maxPosts = (json.feed.entry.length <= maxNumberOfPostsPerLabel) ?
json.feed.entry.length : maxNumberOfPostsPerLabel;
for (var i = 0; i < maxPosts; i++) {
var entry = json.feed.entry[i];
var alturl;

for (var k = 0; k < entry.link.length; k++) {
if (entry.link[k].rel == 'alternate') {
alturl = entry.link[k].href;
break;
}
}
var li = document.createElement('li');
var a = document.createElement('a');
a.href = alturl;

if(a.href!=location.href) {
var txt = document.createTextNode(entry.title.$t);
a.appendChild(txt);
li.appendChild(a);
ul.appendChild(li);
}
}
for (var l = 0; l < json.feed.link.length; l++) {
if (json.feed.link[l].rel == 'alternate') {
var raw = json.feed.link[l].href;
var label = raw.substr(homeUrl3.length+13);
var k;
for (k=0; k<20; k++) label = label.replace("%20", " ");
var txt = document.createTextNode(label);
var h = document.createElement('b');
h.appendChild(txt);
var div1 = document.createElement('div');
div1.appendChild(h);
div1.appendChild(ul);

<b:loop values='data:post.labels' var='label'>
textLabel = "<data:label.name/>";

var test = 0;
for (var i = 0; i < labelArray.length; i++)
if (labelArray[i] == textLabel) test = 1;
if (test == 0) {
labelArray.push(textLabel);
var maxLabels = (labelArray.length <= maxNumberOfLabels) ?
labelArray.length : maxNumberOfLabels;
if (numLabel < maxLabels) {
search10(homeUrl3, textLabel);
