I discovered a strange problem !
Did anybody sever swa that ?!
When I load my Template with a string from within the code, it's
working !
ex :
template=Xtemplate::XMLTemplate.new(<<EOS)
[...content of the XHTML template here...]
EOS

But, if my template is in a separated file it's not working, I load it
like this :
template = Xtemplate::XMLTemplate.new(IO.read("../acteurs/acteurs.htm")

Does somene know where there is a problem ?
Thank by advance

Simonced.
