An XML DOM Level 2 Core implementation in Lua, based on the (Lua)Expat parser.
This library is under early development and does not have everything implemented
yet. Scan the code for "TODO:" to see what is still to be done.
local DOM = require("expadom.DOMImplementation")()
local doc, root = DOM:createDocument(nil, "root")
root:appendChild(doc:createComment("let's create an address list"))
local list = doc:createElement("addresses")
list:setAttribute("country", "Netherlands")
root:appendChild(list)
local addr = doc:createElement("address")
list:appendChild(addr)
addr:appendChild(doc:createTextNode("address goes here"))
local xml_written = table.concat(doc:write())
-- result (formatting added for readability):
-- <?xml version="1.0" encoding="UTF-8"?>
-- <root>
-- <!--let's create an address list-->
-- <addresses country="Netherlands">
-- <address>address goes here</address>
-- </addresses>
-- </root>
-- now parse the document again:
local xml_parsed = require("expadom").parseDocument(xml_written)
local address = xml_parsed:getElementsByTagName("address")[1]
print(address.childNodes[1].nodeValue) --> "address goes here"The documentation and reference is available in the /docs folder, and online.
Source code and downloads are available from the Github project page. Installation is typically easiest using LuaRocks.
Expadom depends on the following packages:
- LuaExpat for parsing XML. This requires that libexpat itself is also installed.
- The Lua module compat53 is required
for UTF-8 support on Lua versions lacking the
utf8module (pre Lua 5.3).
When installing through LuaRocks, libexpat must be installed manually, the other
dependencies will be dealt with by LuaRocks.

- Feat: return root element as well when creating a document (DOMimplementation) #5
- Most of the DOM level 2 has been implemented
