    <channel id="2"           />
    <channel id="x" xz2="600" />
</channels>
]]
local data_path = "//channel/@id"

-- xmlpath.load(data string)
local node, err = xmlpath.load(data)
if err then error(err) end

-- xmlpath.compile(path string)
local path, err = xmlpath.compile(data_path)
if err then error(err) end

-- path:iter(node)
local iter = path:iter(node)

Overview

Package xmlpath provides xmlpath for lua.

Example (Full)

xmlpath.compile, xmlpath.load, xmlpath_node_ud, xmlpath_path_ud, xmlpath_iter_ud

state := lua.NewState()
Preload(state)
source := `
local xmlpath = require("xmlpath")

local data = [[
<channels>
    <channel id="1" xz1="600" />
    <channel id="2"           />
    <channel id="x" xz2="600" />
</channels>
]]
local data_path = "//channel/@id"

local node, err = xmlpath.load(data)
if err then error(err) end

local path, err = xmlpath.compile(data_path)
if err then error(err) end

local iter = path:iter(node)

for k, v in pairs(iter) do print(v:string()) end
`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}
