XML Defined l l l XML or Extensible Markup Language is a meta-markup language that provides a format for describing structured data XML is the universal format for structured documents and data XML provides a standard for more precise declarations of content and more meaningful search results across loosely coupled applications

XML Defined (cont. ) l l XML 1. 0 Recommendation 2 -10 -1998 The rules (in 117 seconds): Ø Ø Ø Element Nesting Optional Closing Tags Single Tag Elements Double-quote Value Delimiters Case Sensitivity Well Formed

Element Nesting l HTML – Relaxed about nesting elements for example: Ø This text has <B>bold, <I>bold italic </B>and italic </I>words. l XML – Each element must Nest completely or not at all for example: Ø This text has <B> bold, <I>bold italic </I></B> <I>and italic </I>words.

Optional Closing Tags l l HTML is also relaxed when comes to closing tags. For example: Ø <LI>List One <LI>List Two <LI>List Three XML (Well-formed) syntax requires that closing element tags are used. For Example: Ø <MYLIST> <LISTITEM>List Item One </LISTITEM> <LISTITEM>List Item Two </LISTITEM> <LISTITEM>List Item Three </LISTITEM> </MYLIST>

Single Tag Elements l Some elements in HTML do not enclose content, and hence do not have a closing tag. For example: Ø l <HR> <HR SIZE=” 5”> XML does not have a single tag element concept. There must be a backslash character with the single element tag. For example: Ø <RULE /> <RULE SIZE=” 5” />

Double-Quote Value Delimiters l HTML allows attribute values to be used with or without double-quotes, as long as they don’t contain spaces. For example: Ø Ø l <HR SIZE=5> <H 1 ALIGN=CENTER>This is a Heading</H 1> In XML single or double quotes must always be used. For example: Ø Ø <HR SIZE=” 5”> <H 1 ALIGN=”CENTER”>This is a Heading</H 1>

Case Sensitivity l l XML is case sensitive unlike HTML. Here is an HTML file that would fail as a well-formed XML file: Ø <H 1 ALIGN=”CENTER”>This is a heading </h 1>

Well Formed Document l XML Declaration – helps other applications decipher the content of the document. The syntax looks like this: Ø l <? xml version=” 1. 0”? > Unique Root Element Ø <Person> <First. Name>Bill</First. Name> <Last. Name>Anderson</Last. Name> </Person>
