API blogger xml

The themes for blogger are XLST.

Into http://ift.tt/1iW5GHA I can't find none sample XML.

What I look in for is something like that or close to it :

<blog>
    <name />
    ...
    <posts>
        <post>
            <title />
            <content />
            <comments>
            ...
            <comments>
        </post>
        </post>
            <title />
            <content />
        </post>
