How to check the text assigned to a Variable

[micheus]

I ended up having to use Split instead of Tokens.

ggaliens had introduced me re before, but I always forget about it.

About the xml management, I already thought to suggest it too, but I know how complicated can be learn something new when we are capable to get the same result using what we know.

I think, that after you finish coding the plugin, you could take a look about use a xml builder in order to optimize/organize your final code - think it as a version review.

As I saw in the yafaray documentation:

Each XML document should start with naming the XML version: <?xml version="1.0"?>

it's xml 1.0 compliant, so you can use xmerl module for that.
Here you have a simple example how to generate an xml file from Erlang.
