Trying to parse external files to drive content

So I wanted to make a simple application. I like ot play fighting games (Mortal Kombat, Street Fighter, etc). I have found web pages and printables with movelists of how to do various moves for each character, so I decided to consolidate all of these into an app I could put on a phone or tablet so when i play the games, i can click on a game, click on a character, and be given their moves right before me. I was planning on it being a simple app. I have symbols for each of the inputs (directions, punches, kicks, etc.), and had made a scene that was a horizontal bar with a text label on it. My plan was to populate a scene with these bars, use the label to label the move, and then add sprites for each of the inputs (for example, in mortal kombat, Scorpion's harpoon would have a text label with the text "Harpoon", followed by a "back" sprite, a "back" sprite, and a "punch_low" sprite. I was planning on creating XMl files for each game, which would include inside of them the list of characters, and each character would have a list of moves, and each move would have a list of inputs. I am trying to get the XMLParser to work and canNOT figure it out, at all. Google searches are pointless, and the most help I've gotten is a generic reply that got me to use the .read() command after the .open() command, so now i can get to my root node, but can't get to anything inside. Here is an XML snippet to begin to show what I was thinking of creating to accompany this:

<?xml version="1.0" encoding="UTF-8"?>
        <name>Liu Kang</name>

Using this code, i can get it to read the name "chars"

var data ="res://assets/xmls/mk1.xml")

and that's all i can do. I have tried reading the node_data, seeing if i could get attributes, etc. and nothing. Is there a better way than XML? I have looked at json parsing, but am not familiar with json so figured it would be even more difficult. Can i do this in a plain text file and read it?

Sigh... this will be such an easy thing to develop once i get this part figured out. Its just a bunch of data entry and loading the right file, then i have to add either a sprite or a label to show what the inputs are. Any help at all is appreciated. Thanks so much guys!

    You have to keep calling to move through the nodes.

    However, if can switch JSON this will a lot easier. Parsing XML in Godot is very low level. With JSON you can just run var dict = {}; dict.parse_json(json_text) and the dictionary will be filled with the data. Saving is also easy since you can do dict.to_json(). You will have to use the File API to save/load the content from file, but it's not much of a burden and certainly easier than using XMLParser.

    BTW, if you want a sample code with XMLParser, you can check my Tiled Importer (link points to proper line where it starts):

    Tiled exports JSON so I use that by default, but also convert the XML format to JSON with this function.

    Thanks! I'm looking into json now.

    Yeah, working with json is much easier. I did convert all my XML files to json (using an online tool) to use on my Sokoban game.
