	<brief_description>
		Low-level class for creating parsers for [url=https://en.wikipedia.org/wiki/XML]XML[/url] files.
	</brief_description>
	<description>
		This class can serve as base to make custom XML parsers. Since XML is a very flexible standard, this interface is low-level so it can be applied to any possible schema.

	<methods>
		<method name="get_attribute_count" qualifiers="const">
			<return type="int" />
			<description>
				Gets the amount of attributes in the current element.
			</description>
		</method>
		<method name="get_attribute_name" qualifiers="const">
			<return type="String" />
			<argument index="0" name="idx" type="int" />
			<description>
				Gets the name of the attribute specified by the index in [code]idx[/code] argument.
			</description>
		</method>
		<method name="get_attribute_value" qualifiers="const">
			<return type="String" />
			<argument index="0" name="idx" type="int" />
			<description>
				Gets the value of the attribute specified by the index in [code]idx[/code] argument.
			</description>
		</method>
		<method name="get_current_line" qualifiers="const">
			<return type="int" />
			<description>
				Gets the current line in the parsed file (currently not implemented).
			</description>
		</method>
		<method name="get_named_attribute_value" qualifiers="const">
			<return type="String" />
			<argument index="0" name="name" type="String" />
			<description>
				Gets the value of a certain attribute of the current element by name. This 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" />
			<argument index="0" name="name" type="String" />
			<description>
				Gets the value of a certain attribute of the current element by name. This will return an empty [String] if the attribute is not found.
			</description>
		</method>
		<method name="get_node_data" qualifiers="const">
			<return type="String" />
			<description>
				Gets the contents of a text node. This will raise an error in any other type of node.
			</description>
		</method>
		<method name="get_node_name" qualifiers="const">
			<return type="String" />
			<description>
				Gets the name of the current element node. This will raise an error if the current node type is neither [constant NODE_ELEMENT] nor [constant NODE_ELEMENT_END].
			</description>
		</method>
		<method name="get_node_offset" qualifiers="const">
			<return type="int" />
			<description>
				Gets the byte offset of the current node since the beginning of the file or buffer.
			</description>
		</method>
		<method name="get_node_type">
			<return type="int" enum="XMLParser.NodeType" />
			<description>
				Gets the type of the current node. Compare with [enum NodeType] constants.
			</description>
		</method>
		<method name="has_attribute" qualifiers="const">
			<return type="bool" />
			<argument index="0" name="name" type="String" />
			<description>
				Check whether the current element has a certain attribute.
			</description>
		</method>
		<method name="is_empty" qualifiers="const">
			<return type="bool" />
			<description>
				Check whether the current element is empty (this only works for completely empty tags, e.g. [code]&lt;element \&gt;[/code]).
			</description>
		</method>
		<method name="open">
			<return type="int" enum="Error" />
			<argument index="0" name="file" type="String" />
			<description>
				Opens an XML file for parsing. This returns an error code.
			</description>
		</method>
		<method name="open_buffer">
			<return type="int" enum="Error" />
			<argument index="0" name="buffer" type="PoolByteArray" />
			<description>
				Opens an XML raw buffer for parsing. This returns an error code.
			</description>
		</method>
		<method name="read">
			<return type="int" enum="Error" />
			<description>
				Reads the next node of the file. This returns an error code.
			</description>
		</method>
		<method name="seek">
			<return type="int" enum="Error" />
			<argument index="0" name="position" type="int" />
			<description>
				Moves the buffer cursor to a certain offset (since the beginning) and read the next node there. This returns an error code.
			</description>
		</method>
		<method name="skip_section">
			<return type="void" />
			<description>
				Skips the current section. If the node contains other elements, they will be ignored and the cursor will go to the closing of the current element.
			</description>
		</method>
