  6. Question 2: Create XML Documents • Create a serialized (XML) document representation of the following XML Tree:

  7. Question 2: Create XML Documents XML: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE Pro PUBLIC "ProjectID" "Pro.dtd" > <CompanyProjects> </CompanyProjects>

  8. Question 2: Create XML Documents XML: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE Pro PUBLIC "ProjectID" "Pro.dtd" > <CompanyProjects> <Project> </Project> <Project> </Project> </CompanyProjects>

  9. Question 2: Create XML Documents XML: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE Pro PUBLIC "ProjectID" "Pro.dtd" > <CompanyProjects> <Project> <Name>Product X</Name> <Number>1</Number> <Location>Ballaire</Location> <Worker> </Worker> <Worker> </Worker> </Project> <Project> </Project> </CompanyProjects>

  10. Question 2: Create XML Documents XML: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE Pro PUBLIC "ProjectID" "Pro.dtd" > <CompanyProjects> <Project> <Name>Product X</Name> <Number>1</Number> <Location>Ballaire</Location> <Worker> <Ssn>123456789</Ssn> <Last_Name>Smith</Last_Name> <Hours>32.5</Hours> </Worker> <Worker> <Ssn>435435435</Ssn> <First_Name>Joyce</First_Name> <Hours>20.0</Hours> </Worker> </Project> <Project> </Project> </CompanyProjects>

  11. Question 3: Create a DTD • Create a valid DTD document for the following XML Tree:

  12. Question 3: Create a DTD DTD: <?xml version="1.0" encoding="UTF-8"?> <!ELEMENT CompanyProjects (Project*)> <!ELEMENT Project (Name?, Number?, Location?, Worker*)>

  13. Question 3: Create a DTD DTD: <?xml version="1.0" encoding="UTF-8"?> <!ELEMENT CompanyProjects (Project*)> <!ELEMENT Project (Name?, Number?, Location?, Worker*)> <!ELEMENT Name (#PCDATA)> <!ELEMENT Number (#PCDATA)> <!ELEMENT Location (#PCDATA)> <!ELEMENT Worker (Ssn, Last_Name?, First_Name?, Hours)>

  14. Question 3: Create a DTD DTD: <?xml version="1.0" encoding="UTF-8"?> <!ELEMENT CompanyProjects (Project*)> <!ELEMENT Project (Name?, Number?, Location?, Worker*)> <!ELEMENT Name (#PCDATA)> <!ELEMENT Number (#PCDATA)> <!ELEMENT Location (#PCDATA)> <!ELEMENT Worker (Ssn, Last_Name?, First_Name?, Hours)> <!ELEMENT Ssn (#PCDATA)> <!ELEMENT Last_Name (#PCDATA)> <!ELEMENT First_Name (#PCDATA)> <!ELEMENT Hours (#PCDATA)>

  15. Question 3: Create a DTD --Note: There are no attributes but I could show them some attributes, for examples: <!ATTLIST element_nameattribute_nameattribute_typedefault_value> <!ATTLIST Project startTime CDATA #REQUIRED> <!ATTLIST Worker gender CDATA> --Element allowable_contents (#PCDATA) can also be EMPTY, ANY, Children elements or MIXED CONTENT (#PCDATA with Children) --#REQUIRED can be #IMPLIED or #FIXED --CData = Character Data --PCData = Passed Character Data
