Elements

41	41	There are three properties of Elements that return tables of data. They are ''child_nodes'', ''attributes'', and ''style''. They are implemented in C++ as [wiki:documentation/LuaManual/ProxyTables proxy tables] with regards to their Lua interface.
42	42
43		The ''child_nodes'' property is accessed as an array; it is indexed numerically, from the front or back~~, and its length can be queried by getting the actual Lua table from the proxy table, and using the Lua length operator(#) on that table~~.
	43	The ''child_nodes'' property is accessed as an array; it is indexed numerically, from the front or back.
44	44
45	45	''child_nodes'' is an array of element types. The array only includes visible elements; Lua has no way of querying [wiki:documentation/C++Manual/HiddenElements hidden elements]. The following example iterates over all of an element's children, printing their tag names, ids and classes:
46	46
47	47	{{{
48		for key,child in ipairs(element.child_nodes~~:GetTable()~~) do
	48	for key,child in ipairs(element.child_nodes) do
49	49	local address = child.tag_name
50	50
67	67
68	68	{{{
69		for name,attribute in pairs(element.attributes~~:GetTable()~~) do
	69	for name,attribute in pairs(element.attributes) do
70	70	print key .. ": " .. attribute
71	71	end
