retrieve list of all labels in blogger

Question

Is there a way to use gdata api to retrieve the list of all labels in a blogger?

I need to create a menu based on that list, but cannot simply list all posts and get it, because it is a busy blog and has more than 2000 posts.

Answer 1

Here is the most easy way to get a list of labels by using json call:

<script>
    function cat(json){ //get categories of blog & sort them
        var label = json.feed.category;
        var lst=[];
        for (i=0; i<label.length; i++){
          lst[i] = label[i].term ;  
        }
        alert(lst.sort());  //use any sort if you need that 
    }

</script>

<script src="http://yourblog.blogspot.com/feeds/posts/summary?alt=json&max-results=0&callback=cat"></script>

Just use your blog url.

Answer 2

Very simple, I give you two ways

1. With Javascript API First, you must use:

   <script type="text/javascript" src="http://www.google.com/jsapi"></ script> <script type='text/javascript'>
google.load("gdata", "1.x", { packages : ["blogger"] });
</script>

   Second, you can use the code below to retrieve the labels

   postRoot.entry.getCategories()[i].getTerm()

2. With JSON with json, if you want to learn how to retrieve the list of labels, use this object

   json.feed.entry[i].category[j].term

Answer 3

The way I found was using the Blogger's own gadget called Labels. It prints the list of labels and their usage count within some unordered lists(ul) and links(a). You can pull the labels from that after they are loaded using javascript as follows:

$(".list-label-widget-content a").each(function (i, el) {
    var labelText = $(el).text();
    // do what you want with the labels
});

in the end, remove the Labels div element (<div class='widget Label' id='Label1'>)
