如何按标签过滤博客提要

我正在使用Google的Blogger API从我的Blogger博客中检索项目以显示在我的主页上。我使用的是在Blogger开发者博客上提供的Javascript。我想做的是过滤由label返回的条目。我做了很多搜索，但是，尽管看起来这应该很简单，我还没有找到任何明确的方向。

检索Blogger条目的代码如下所示:

function init() {
    // Get your API key from http://code.google.com/apis/console
    gapi.client.setApiKey('xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx');
    // Load the Blogger JSON API
    gapi.client.load('blogger', 'v3', function() {
        // Load the list of posts for code.blogger.com
        var request = gapi.client.blogger.posts.list({
            'blogId': 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
            'fields': 'items(content,title,updated,id,labels)',
            'fetchBodies': true
        });
        request.execute(function(response) {
            var blogger = document.getElementById("blogger");
            var anchor = 0;
            for (var i = 0; i < response.items.length; i++)
            {
                var bloggerDiv = document.createElement("div");
                bloggerDiv.id = "blogger-" + i;
                bloggerDiv.className = "bloggerItem";
                // For the parts of the response, have a look at the result at:
                // http://code.google.com/apis/explorer/#_s=blogger&_v=v2&_m=posts.list&blogId=xxxxxxxxxxxxx
                $(bloggerDiv).append("<h2>" + response.items[i].title + "</h2>");
                var date = response.items[i].updated;
                date = date.replace("T", " ");
                date = date.replace("+03:00", "");
                var printDate = new moment(date);
                $(bloggerDiv).append("<p><span class='byline'>" + printDate.format('dddd, MMMM Do YYYY, h:mm:ss a') + "</span></p>");
                $(bloggerDiv).append(response.items[i].content);
// This logic might be useful to keep around if I decide to do
// something different based on whether or not the last item
// needs different formatting in some way.
//        if (i+1<response.items.length) {
//          $(bloggerDiv).append("<hr>");
//        }
//        $(bloggerDiv).append("<hr>");

                bloggerAnchor = document.createElement("a");
                bloggerAnchor.name = "blogger-" + response.items[i].id;
                blogger.appendChild(bloggerAnchor);
                blogger.appendChild(bloggerDiv);
                anchor = anchor + 1;
            }
            // find out which anchor the user wanted...
            var hashVal = window.location.hash.substr(1);
// ... then jump to that position:
            location.hash = "#" + hashVal;
        });
    });
}

返回博客上的所有内容。如何让它只返回label="XYZ"的条目?

我认为这将是现在回答，但我在SO上发现的一个问题似乎相关包含链接，现在已经死了，所以他们持有的任何信息现在是不可用的。
