How to check the text assigned to a Variable

[oort]

Micheus,
Thanks... I ended up having to use Split instead of Tokens. I was getting my "1" and "2" but it was not recognized as an integer so "UpperLayer" was not being defined. It took me a while to figure it out but it is working now. Since Blend modes can only have two textures in YafaRay I can probably use the simpler version of your code for now. Unless further testing proves that it is needed...

Thanks again!

Split=re:split(Texname,"_",[{return, list}]),
Num=lists:last(Split),
UpperLayer =
case Num of
"1" -> "<upper_layer sval=\""++UpperLayerName++"\"/>";
_ -> ""
end,

%% End Identify Modulator #

ggaliens,
No idea what a real xml parser does but I am sure it would require skills I do not yet have...
