XHTML Tutorial - What Is PCDATA
(Continued from previous topic...)
What Is PCDATA?
PCDATA stands for Parsed Character DATA. Here are some basic rules about PCDATA:
- PCDATA is a string of characters and XHTML entities.
- XHTML entities are escape sequences used to refer to special characters that
are not so easy to enter them in a text document. For example, "©" is XHTML
entity referring to the copyright character: "©".
- 3 special characters: "<", ">", and "&" can not be used directly in PCDATA.
They must be replaced by the corresponding XHTML entities: "<",
">", and "&".
- If "<" is used in PCDATA, it will be parsed as the beginning of a XHTML tag.
- If "&" is used in PCDATA, it will be parsed as the beginning of a XHTML entity.
