DTD Building Blocks

This lesson is part of XML · All levels

Summary

The DTD block consists of an element declaration, an attribute declaration, an entity declaration, as well as a content type PCDATA and CDATA. PCDATA contains text that remains parsed by the parser so the mark is less than required to be exported, whereas CDATA is completely missed by the parser. Understanding these blocks is the foundation of writing a true DTD.

Key points

PCDATA = parsed character data, text that parsed parser
CDATA = unparsed data character, secure for raw text
Declaration of the elements: <!ELEMENT name (content)>
Attributes are defined as:
Entity declaration: <!ENTITY name "value">
