value()

public

Returns the value of this entity. At the moment, only internal entities are processed. If the value contains internal references (IE, %blah;), those are replaced with their values. IE, if the doctype contains: <!ENTITY % foo “bar”> <!ENTITY yada “nanoo %foo; nanoo> then: doctype.entity(‘yada’).value #-> ”nanoo bar nanoo“
