Descripción

xml_set_character_data_handler(XMLParser $parser, callable|string|null $handler): true

Establece los gestores de datos de caracteres para el analizador XML parser.

Parámetros

parser

The XML parser.

handler

If null is passed, the handler is reset to its default state.

Advertencia

An empty string will also reset the handler, however this is deprecated as of PHP 8.4.0.

If handler is a callable, the callable is set as the handler.

If handler is a string, it can be the name of a method of an object set with xml_set_object().

Advertencia

This is deprecated as of PHP 8.4.0.

Advertencia

As of PHP 8.4.0, the callable is checked to be valid while setting the handler, not when it is called. This means that xml_set_object() must be called prior to setting a method string as the callback. However, as this behaviour is also deprecated as of PHP 8.4.0, using a proper callable for the method is recommended instead.

La firma del gestor debe ser:

handler(XMLParser $parser, string $data): void
parser
The XML parser calling the handler.
data
Datos de caracteres como string.

El gestor de datos es llamado para cada fragmento de texto de un documento XML. Puede ser llamado múltiples veces para cada fragmento (por ejemplo, para strings no ASCII).

Valores devueltos

Siempre devuelve true.

Versión Descripción

8.4.0 The validity of handler as a callable is now checked when setting the handler instead of checking when calling it.
8.0.0 parser expects an XMLParser instance now; previously, a valid xml resource was expected.
