The fact that the option Case Folding even exists displays a through misunderstanding about what XML is. I find it really disappointing that this article opens with this "feature", instead of ignoring it, or to mention it as a bug. I'm a PHP user myself, doing occasional XML transforms with the Sabloton interface. However, there are still some bugs remaining (in both Sablotron 0.97 and the PHP bindings) which can get in the way (e.g. namespaces and xsl:copy-of is mangled). Admittedly, I haven't used the XML_Transformer until now. Then again, it strikes me as odd why the developers didn't opt for the standardized SAX(2) interface. Cheers, Joe.

  I mentioned case-folding mainly for two reasons:

  
  1 - By default PHP's xml_parse() XML_OPTION_CASE_FOLDING option is enabled.

  
  (please see http://php.linux.pt/manual/en/ref.xml.php#xml.case-folding)

  
  2 - By default XML_Transformer's caseFolding option is disabled.

  
  XML is case sensitive, and XML_Transformer tries to respect it. The 'problem' is in PHP's XML parsing support.
