[R] Get XML or JSON data from api into data frame

I am new to R in general and ways to retrieve XML or JSON data in
particular. I have tried to get information through the XML package
and various websites without being able to do exactly what I want. I
hope someone of you can give me some help.
I want to retrieve information about movies from IMDB or rather the
unofficial api, www.imdbapi.com. I have a vector with a lot movie-ids
according to IMDB standard. To give just a few:
ids <-c("tt0110074", "tt0096184", "tt0081568", "tt0448134", "tt0079367")
Now, I want to create a data frame where each of the movies refer to
one line and the other information is retrieved from the api. This can
be retrieved either as XML data or JSON data, e.g.
Where i refer to the movie-id, i.e. the information I have in my
vector. They are all in the format ttXXXXXXX
I have tried to use the XML package, but I have not been able to get
the data into a workable data frame. I take for granted that this is
due to my limited knowledge about R and I aim to learn more, but right
now I am in a bit of a hurry since this unofficial api will be taken
of the web in a few days, and I really want to crete this data frame
for further analysis.
Any help would be greatly appreciated.
All the best,
