    <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)

for k, v in pairs(iter) do print(v:string()) end
