	<description>
		Provides a low-level interface for creating parsers for [url=https://en.wikipedia.org/wiki/XML]XML[/url] files. This class can serve as base to make custom XML parsers.
		To parse XML, you must open a file with the [method open] method or a buffer with the [method open_buffer] method. Then, the [method read] method must be called to parse the next nodes. Most of the methods take into consideration the currently parsed node.
		Here is an example of using [XMLParser] to parse an SVG file (which is based on XML), printing each element and its attributes as a dictionary:
		[codeblocks]
		[gdscript]
		var parser = XMLParser.new()
		parser.open("path/to/file.svg")
		while parser.read() != ERR_FILE_EOF:
			if parser.get_node_type() == XMLParser.NODE_ELEMENT:
				var node_name = parser.get_node_name()
				var attributes_dict = {}
				for idx in range(parser.get_attribute_count()):
					attributes_dict[parser.get_attribute_name(idx)] = parser.get_attribute_value(idx)
				print("The ", node_name, " element has the following attributes: ", attributes_dict)
		[/gdscript]
		[csharp]
		var parser = new XmlParser();
		parser.Open("path/to/file.svg");
		while (parser.Read() != Error.FileEof)
		{
			if (parser.GetNodeType() == XmlParser.NodeType.Element)
			{
				var nodeName = parser.GetNodeName();
				var attributesDict = new Godot.Collections.Dictionary();
				for (int idx = 0; idx &lt; parser.GetAttributeCount(); idx++)
				{
					attributesDict[parser.GetAttributeName(idx)] = parser.GetAttributeValue(idx);
				}
				GD.Print($"The {nodeName} element has the following attributes: {attributesDict}");
			}
		}
		[/csharp]
		[/codeblocks]

	<methods>
		<method name="get_attribute_count" qualifiers="const">
			<return type="int" />
			<description>
				Returns the number of attributes in the currently parsed element.
				[b]Note:[/b] If this method is used while the currently parsed node is not [constant NODE_ELEMENT] or [constant NODE_ELEMENT_END], this count will not be updated and will still reflect the last element.
			</description>
		</method>
		<method name="get_attribute_name" qualifiers="const">
			<return type="String" />
			<param index="0" name="idx" type="int" />
			<description>
				Returns the name of an attribute of the currently parsed element, specified by the [param idx] index.
			</description>
		</method>
		<method name="get_attribute_value" qualifiers="const">
			<return type="String" />
			<param index="0" name="idx" type="int" />
			<description>
				Returns the value of an attribute of the currently parsed element, specified by the [param idx] index.
			</description>
		</method>
		<method name="get_current_line" qualifiers="const">
			<return type="int" />
			<description>
				Returns the current line in the parsed file, counting from 0.
			</description>
		</method>
		<method name="get_named_attribute_value" qualifiers="const">
			<return type="String" />
			<param index="0" name="name" type="String" />
			<description>
				Returns the value of an attribute of the currently parsed element, specified by its [param name]. This method will raise an error if the element has no such attribute.
			</description>
		</method>
		<method name="get_named_attribute_value_safe" qualifiers="const">
			<return type="String" />
			<param index="0" name="name" type="String" />
			<description>
				Returns the value of an attribute of the currently parsed element, specified by its [param name]. This method will return an empty string if the element has no such attribute.
			</description>
		</method>
		<method name="get_node_data" qualifiers="const">
			<return type="String" />
			<description>
				Returns the contents of a text node. This method will raise an error if the current parsed node is of any other type.
			</description>
		</method>
		<method name="get_node_name" qualifiers="const">
			<return type="String" />
			<description>
				Returns the name of a node. This method will raise an error if the currently parsed node is a text node.
				[b]Note:[/b] The content of a [constant NODE_CDATA] node and the comment string of a [constant NODE_COMMENT] node are also considered names.
			</description>
		</method>
		<method name="get_node_offset" qualifiers="const">
			<return type="int" />
			<description>
				Returns the byte offset of the currently parsed node since the beginning of the file or buffer. This is usually equivalent to the number of characters before the read position.
			</description>
		</method>
		<method name="get_node_type">
			<return type="int" enum="XMLParser.NodeType" />
			<description>
				Returns the type of the current node. Compare with [enum NodeType] constants.
			</description>
		</method>
		<method name="has_attribute" qualifiers="const">
			<return type="bool" />
			<param index="0" name="name" type="String" />
			<description>
				Returns [code]true[/code] if the currently parsed element has an attribute with the [param name].
			</description>
		</method>
		<method name="is_empty" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if the currently parsed element is empty, e.g. [code]&lt;element /&gt;[/code].
			</description>
		</method>
		<method name="open">
			<return type="int" enum="Error" />
			<param index="0" name="file" type="String" />
			<description>
				Opens an XML [param file] for parsing. This method returns an error code.
			</description>
		</method>
		<method name="open_buffer">
			<return type="int" enum="Error" />
			<param index="0" name="buffer" type="PackedByteArray" />
			<description>
				Opens an XML raw [param buffer] for parsing. This method returns an error code.
			</description>
		</method>
		<method name="read">
			<return type="int" enum="Error" />
			<description>
				Parses the next node in the file. This method returns an error code.
			</description>
		</method>
		<method name="seek">
			<return type="int" enum="Error" />
			<param index="0" name="position" type="int" />
			<description>
				Moves the buffer cursor to a certain offset (since the beginning) and reads the next node there. This method returns an error code.
			</description>
		</method>
		<method name="skip_section">
			<return type="void" />
			<description>
				Skips the current section. If the currently parsed node contains more inner nodes, they will be ignored and the cursor will go to the closing of the current element.
			</description>
		</method>
