In what Software and in what language?
And what has coplanarity (in the subject) got to do with the problem?

Sorry, question is way too vague to get a reply without those details.

The language doesn't matter, I would only need the cloud points of the full structure, but I don't know how I could get them according to the file. Thanks in advance.

Well, simplest way would be to take this info:

Create locators and set the position for each.. the first one would be.
X = 27.096141893
Y = 67.088581299
Z = 10.979694884

The language matters a lot.
You have an XML file there, an XML parser is all you need, it will build you a tree/structure of the data and allow you to query it. You will go in the branch ROOF, fetch all attributes tagged as POINT, and store the three following values into an array at the index corresponding to the fourth value (id).

Unless you plan on writing the parser yourself, which would be a colossal waste of time, and chances are if you're asking these questions is not what you're after, the language will determine what the standard libraries available will be, and the app will determine how they can be stored in a way that the scene can have a use for them.

You are remaining awfully generic.
Your question right now literally amounts to "How do I read a text file to do non-descript stuff with it?". It still can't be answered, because those actions are heavily language dependent (standard library or optional libraries coming with it, actually, but same thing at this point).

You want an XML library to parse and sort your data from that file, that's all that can be said right now. If you're using Python it comes with some respectable ones inbuilt (MiniDom etc.) that will do for simple uses like this. If you're using C++ then nothing in STL is adequate, you will need to get an external library to do the parsing, or cook your own.
