Предопределенные классы

LibXMLError

Свойства

  • 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.

  • file - the filename, or empty if the XML was loaded from a string

  • 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

  • message - the error message
