Issues with XMLParser

Maxpilot

Hi, wrote a little script for parsing an xml-file to make a list with nested dictionaries and lists of the form: [{"cdata": string, "childs": list, "name": string}] (childs listed under the "childs" - key).

extends Node

var mainList = []
var xp = XMLParser.new()
var err



func _init():
	
	var art
	var subdict
	
	xp.open("res://test2.xml")
	
	while xp.read() == 0:
		art = xp.get_node_type()
		print(art)
		
		if art == XMLParser.NODE_ELEMENT:
			subdict = {}
			subdict["name"] = xp.get_node_name()
			subdict["cdata"] = ""
			subdict["childs"] = []
			mainList.append(subdict)
			accu(subdict)
	print(mainList)



func accu(dict):
	
	var art
	var subdict
	
	while xp.read() == 0:
		art = xp.get_node_type()
		print(art)
		if art == XMLParser.NODE_ELEMENT:
			subdict = {}
			subdict["name"] = xp.get_node_name()
			subdict["cdata"] = ""
			subdict["childs"] = []
			dict["childs"].append(subdict)
			accu(subdict)
		elif art == XMLParser.NODE_ELEMENT_END:
			return
		elif art == XMLParser.NODE_TEXT:
			var untrimmed = xp.get_node_data()
			var trimmed = untrimmed.strip_edges()
			
			if ! trimmed.empty():
				dict["cdata"] = dict["cdata"] + untrimmed

Not complete, no error checking, but it fit my needs. From my point of view there are some issues with text nodes (if I'm not doing someting completely wrong): In UTF-8 the BOM is recognized as NODE_TEXT (minor problem), formating whitespace is recognized as text (to handle this see last lines of code), and last, and thats my question, how can I read data of a CDATA_NODE?

Hi, I'm late to the party but I thank you for your code snippet! it helped me. One thing I noted is missing: In line 45. you only want to go one level deeper if !xp.is_empty()

I'm a little late, but for posterity: when get_node_type() returns NODE_CDATA then calling get_node_name() will return the contents of the cdata section, but in addition to the contents the string will end with the trailing ]]> that ends the cdata section.
