LXII. libxml Functions

简介

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 .

需求

This extension requires libxml >= 2.6.0.

预定义类

LibXMLError

属性

  • 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
