original url from : http://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references
The XML specification does not use the term "character entity" or "character entity reference". The XML specification defines five "predefined entities" representing special characters, and requires that all XML processors honor them. The entities can be
explicitly declared in a DTD, as well, but if this is done, the replacement text must be the same as the built-in definitions. XML also allows other named entities of any size to be defined on a per-document basis.

The table below lists the five XML predefined entities. The "Name" column mentions the entity's name. The "Character" column shows the character. To render the character, the format
&name;
is used; for example,
&
renders as &. The "Unicode code point" column cites the character via standard UCS/Unicode "U+" notation, which shows the character's code point in hexadecimal. The decimal equivalent of the code point is then shown in parentheses. The "Standard"
column indicates the first version of XML that includes the entity. The "Description" column cites the character via its canonical UCS/Unicode name, in English.

NameCharacterUnicode code point (decimal)StandardDescription
quot"U+0022 (34)XML 1.0double
quotation mark
amp&U+0026 (38)XML 1.0ampersand
apos'U+0027 (39)XML 1.0apostrophe
(apostrophe-quote)
lt<U+003C (60)XML 1.0less-than sign
gt>U+003E (62)XML 1.0greater-than sign
The HTML 4 DTDs define 252 named entities, references to which act as mnemonic aliases for certain Unicode characters. The HTML 4 specification requires the use of the standard DTDs and does not allow users to define additional entities.

In the table below, the "Standard" column indicates the first version of the HTML DTD that defines the character entity reference. HTML 4.01 does not provide any new character references.

To use one of these character entity references in an HTML or XML document, enter an ampersand followed by the entity name and a semicolon, e.g., &
