  1. Document Object Model & eXtensible Markup Language DOM & XML Reference : http://www.w3schools.com/Xml/xml_syntax.asp

  2. Document Object Model (DOM) DOM concept: NODE <element></element> An empty node: <element />

  3. XML DOM node relations : Parent Child Sibling parent element node A element node B element node C element node D sibling child

  4. root node element node attribute node #text node XML DOM The NODE object Node types: • Element • Attribute • Text

  5. XML DOM Example <class> <name>2X2</name> <pupil sno="1"> <name>Alan Ang</name> </pupil> <pupil> <name>Brenda Blu</name> </pupil> </class> Element nodes Text node Attribute node

  6. XML DOM Example <class> <name>2X2</name> <pupilsno="1"> <name>Alan Ang</name> </pupil> <pupil> <name>Brenda Blu</name> </pupil> </class> Element nodes Text node Attribute node

  7. XML DOM Example <class> <name>2X2</name> <pupil sno="1"> <name>Alan Ang</name> </pupil> <pupil> <name>Brenda Blu</name> </pupil> </class> Element nodes Text node Attribute node

  8. XML DOM <class> <name>2X2</name> <pupil sno="1"> <name>Alan Ang</name> </pupil> <pupil> <name>Brenda Blu</name> </pupil> </class> Example Element nodes Text node Attribute node

  9. #text “Alan Ang” attributesno= “1” element “pupil” element “name” Node diagram <pupil sno=“1”> <name>Alan Ang</name> </pupil>

  10. XML DOM Assignment 1 (2pts) Write the XML source code for the follow node diagram. Element node Attribute node Text node

  11. XML DOM Assignment 2 (2 pts) Draw the node diagram to illustrate the relationship between all the nodes. Distinguish between element/attribute/text nodes. <class> <name>2X2</name> <pupil sno=“1”> <name>Alan Ang</name> </pupil> <pupil> <name>Betty Blu</name> </pupil> </class>

  12. XML Parts of an XML document • Prolog • Root Element • XML declaration • DTD declaration • Stylesheet declaration • Elements (Nested Elements)

  13. XML Parts of an XML document • Prolog <?xml version="1" ?> <?xml-stylesheet href ="xd.xsl" ?> <!DOCTYPE classes SYSTEM cls.dtd>

  14. XML Parts of an XML document • Elements • Nested child elements • Element Attribute • Data <books> <book id="1" > <author>King James</author> <title>Holy Holly</title> </book> </root>
