How can I get data from XML files?

I am trying to get captions from youtube's API in roblox but it gives me XML code instead of JSON. I'm trying to use string patterns but it wont work.

Here is the code I'm testing with:

for caption in string.gmatch(text, [[<text start=.*</text]]) do
    print(caption)
end

If you want the XML code, here is a small part of it
