XML_XSLT2Processor is a PHP class that lets you pefrorm XSLT 2.0 transformations within PHP by using SAXON or AltovaXML.
This release is a very major step in the development of this extension. It adds support for what was probably the greatest mishap of previous versions - error handling. Now, you can see exactly what went wrong with your transformation, rather then trying to reproduce it in another environment which will give you a message.
The new function getErrors() provides the functionality of both the libxml_get_errors() and libxml_get_last_error() functions. libxml_clear_errors()'s functionality is replicated with the new clearErrors() function.
Detailed documentation about the new features is already available in both English and Bulgarian.
