A packaging of the xml2lua library for neovim
xml2lua is an XML parser written entirely in Lua which doesn't depend on any external C/C++ library. It works for Lua 5.1 to 5.3 and enables:
- parsing an XML string into a Lua Table;
- converting a Lua Table to an XML string.
This version was adapted to work with Lua 5 and can be used in Lua applications, including interactive Digital Television (DTV) http://gingancl.org.br/en[Ginga NCL applications] for the http://www.dtv.org.br[Brazilian DTV System] (worldwide known as https://en.wikipedia.org/wiki/ISDB-T_International[ISDB-T International or ISDB-Tb]).
The original parser was written by Paul Chakravarti and is available on http://lua-users.org/wiki/LuaXml[LuaUsers].
It is important to note, as this is a library instead of a plugin, there is no setup function that has to or can be called
{
"a-usr/xml2lua.nvim"
}require("pckr").add{
"a-usr/xml2lua.nvim",

A simplified example which parses an XML directly from a string is presented below. There are some caveats to deal with when an XML has just one tag. Check the example1.lua for details.
local xml2lua = require("xml2lua")
--Uses a handler that converts the XML to a Lua table
local handler = require("xml2lua.xmlhandler.tree")
local xml = [[
<people>
<person type="natural">
<name>Manoel</name>
<city>Palmas-TO</city>
</person>
<person type="legal">
<name>University of Brasília</name>
<city>Brasília-DF</city>
</person>
</people>
]]
--Instantiates the XML parser
local parser = xml2lua.parser(handler)
parser:parse(xml)
--Manually prints the table (since the XML structure for this example is previously known)
for i, p in pairs(handler.root.people.person) do
print(i, "Name:", p.name, "City:", p.city, "Type:", p._attr.type)
endlocal xml2lua = require("xml2lua")
local people = {
person = {
{name="Manoel", city="Palmas-TO", _attr={ type='natural' } },
{name="Breno", city="Palmas-TO", _attr={ type='legal' } }
}
}
print("People Table\n")
xml2lua.printable(people)
print()
print("XML Representation\n")
print(xml2lua.toXml(people, "people"))This code is freely distributable under the terms of the MIT License.
