## Detailed Description

Entity references refer to previously declared entities.

This will be instantiated by the parser.

## Constructor & Destructor Documentation

## EntityReference()

xmlpp::EntityReference::EntityReference | ( | _xmlNode * | node | ) |

explicit

## ~EntityReference()

xmlpp::EntityReference::~EntityReference | ( |  | ) |

override

## Member Function Documentation

## get_original_text()

ustring xmlpp::EntityReference::get_original_text | ( |  | ) | const

Get the text as read from the XML or DTD file.

Returns
  The escaped text.

## get_resolved_text()

ustring xmlpp::EntityReference::get_resolved_text | ( |  | ) | const

Get the text with character references (like "&#xdf;") resolved.

If the corresponding entity declaration does not contain any reference to another entity, this is the text that the reference would have resolved to if the XML document had been parsed with Parser::set_substitute_entities(true).

Returns
  The text with character references unescaped.
