These functions/constants are available since PHP 5.1.0 and if you have compiled one of the extensions based on libxml, like DOM, SimpleXML and XSLT.
This extension requires » libxml >= 2.6.0.
code - the error's code
column - the column where the error occurred. Please note that this property isn't entirely implemented in libxml and therefore 0 is often returned.

level - the severity of the error (one of the following constants: LIBXML_ERR_WARNING, LIBXML_ERR_ERROR or LIBXML_ERR_FATAL)
line - the line where the error occurred
