Full text search External entities: combining in a single file

Introduction

If the replacement text of some of the external entities is small, all of the entities can be defined in a single file.

This example reads in a file called "entity.set", which contains a set of entity definitions. Each entity definition consists of an external entity name terminated by an equal sign, a "quote" character (which may be anything other than a new line), and the text of the entity terminated by another "quote" character. Optional, non-significant line breaks are allowed following the equal sign and following the closing "quote" of the entity text.

The example assumes that the file "entity.set" is correctly formatted, and makes no provision for the entity not being defined. (If it is not defined, the entity text will be "", the zero-length string, which may or may not be an appropriate fall-back position.)

An example of an "entity.set" file is the following, which contains information specific to processing a set of documents. Different "quotes" are used for illustration.
