I already tried that, and here is the new code:
myy $xslt = XML::XSLT->new ("blog.xsl", warnings => 1, debug => 1);
Alas, same error. I was already making sure that the files did exist and that the variables were being filled, by outputing the vars; I know this isn't a simple file I/O error, in other words.
What I find rather funny is that, when I use the deprecated document_transform function, it kindof works; it prints out only the first template match="/" stylesheet declaration and nothing else.
Furthermore, I know it isn't my XSL or XML files because Xalan works flawlessly. There must be something I'm doing wrong, I just can't find out what, and that error message is not very descriptive (couldn't find anything at byte -1, really? lol)
