Catalog Syntax
A catalog is just an XML document in the syntax defined by the OASIS XML Catalogs standard (http://www.oasis-open.org/committees/entity/specs/cs-entity-xml-catalogs-1.0.html). The root element of this document is catalog, which is in the urn:oasis:names:tc:entity:xmlns:xml:catalog namespace. The catalog element contains public elements that remap public IDs and system elements that remap system IDs. Example 47-1 shows a simple catalog that maps the public ID for DocBook to a file in the local file system.
Example 47-1. A Catalog Document
<?xml version="1.0"?> <catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"> <public publicId="-//OASIS//DTD DocBook XML V4.2//EN" uri="file:///opt/xml/docbook/docbookx.dtd"/> </catalog> ... |
