field names with colon in xml file

aster94 commented 4 years ago

hello @manoelcampos I have a xml files that in the fields has some colon, is it possible to read it?

This is what i tried and below there is an example file:

local xml2lua = require("xml2lua")
local handler = require("xmlhandler.tree")
local xml = xml2lua.loadFile("file.xml")
local parser = xml2lua.parser(handler)
parser:parse(xml)
local p= handler.x.rdf

But looks like that it is not working

Hello @aster94

I haven't seen any issues when using the tree handler for your XML. If you've found some issue, please be specific.

aster94 commented 4 years ago

This means I am making it wrong because I wasn't able to read it. How do you access the values with a colon? If I do

local xml2lua = require("xml2lua")
local handler = require("xmlhandler.tree")
local xml = xml2lua.loadFile("file.xml")
local parser = xml2lua.parser(handler)
parser:parse(xml)
local p= handler.x.rdf:li

The colon doesn't work

manoelcampos commented 4 years ago

That is a lua-related issue. Just use:

local p = handler.x["rdf:li"]

aster94 commented 4 years ago

You are completely right, that worked, sorry to bother you

manoelcampos commented 4 years ago

No problem.
