详细描述

The QXmlErrorHandler class provides an interface to report errors in XML data.

If you want your application to report errors to the user or to perform customized error handling, you should subclass this class.

You can set the error handler with QXmlReader::setErrorHandler ().

Errors can be reported using warning (), error () 和 fatalError (), with the error text being reported with errorString ().

成员函数文档编制

[虚拟] QXmlErrorHandler:: ~QXmlErrorHandler ()

Destroys the error handler.

[pure virtual] bool QXmlErrorHandler:: error (const QXmlParseException & exception )

A reader might use this function to report a recoverable error. A recoverable error corresponds to the definiton of "error" in section 1.2 of the XML 1.0 specification. Details of the error are stored in exception .

The reader must continue to provide normal parsing events after invoking this function.

若此函数返回 false the reader stops parsing and reports an error. The reader uses the function errorString () to get the error message.

[pure virtual] QString QXmlErrorHandler:: errorString () const

The reader calls this function to get an error string if any of the handler functions returns false .

[pure virtual] bool QXmlErrorHandler:: fatalError (const QXmlParseException & exception )

A reader must use this function to report a non-recoverable error. Details of the error are stored in exception .

若此函数返回 true the reader might try to go on parsing and reporting further errors, but no regular parsing events are reported.

[pure virtual] bool QXmlErrorHandler:: warning (const QXmlParseException & exception )

A reader might use this function to report a warning. Warnings are conditions that are not errors or fatal errors as defined by the XML 1.0 specification. Details of the warning are stored in exception .

若此函数返回 false the reader stops parsing and reports an error. The reader uses the function errorString () to get the error message.
