How can I get the app version of comment at the google play?

How can I get the app version of comment at the google play?

I can only get the comment date, but it seems there is no url/api to get
the corresponding version of specific comment. I've already tried this:
https://code.google.com/p/android-market-api/ It does not contains the
version number:
"comments": [
{
"rating": 5,
"creationTime": 1269710736815,
"authorName": "Nate Kidwell",
"text": "Tremendous application. More examples would be great (as
would integrated rubydocs), but awesome all the same.",
"authorId": "04441815096871118032"
},
...
Help me pls!!
