  8. XML Sources and Dialects • XML Data Sources • Files System, URL, Memory, Web Service • Messages: HTTP, JMS / WebSphere MQ • Repositories : LDAP directories, RDBMS • Applications: TAMeb, FIM, web pages • XML dialects (Markup Languages) • Identity management • DSML • SPML • Web Services • SOAP • Security • SAML

  9. XML Technology Review

  10. XML • eXtensible Markup Language • Metalanguage - used to create other languages • Has become a universal data-exchange format • You need to ensure that XML is • Well-Formed: Structure follows XML syntax rules • Valid: Structure conforms to a Schema

  11. What is a XML Node ? • An XML node is a tree, containing an open tag, contents, and a close tag • <foo id=“123”>This is <bar>an element</bar></foo> • Here, the tag named ‘foo’ encloses the contents and attributes of the Node • In this case node with the tag ‘foo’ contains a node with the tag ‘bar’ also. There is another notion used in XML literature called Element, that is skipped here to keep things simple

  12. XML is a Nested Tree Order Node Depicted <?xml version="1.0" encoding="UTF-8" standalone="no"?> <IBM> <eFruit> <FruitSales> <Order> <OrderId OrderState="ReadOnly">E0001DU9</OrderId> <Items> <Fruit> <FruitName>Grapes</FruitName> <FruitCount>12</FruitCount> </Fruit> <Fruit> <FruitName>Apples</FruitName> <FruitCount>3</FruitCount> </Fruit> </Items> </Order> </FruitSales> </eFruit> </IBM> OrderID items items OrderState fruit fruit fruitname fruitcount • Nodes • Branch nodes contain children • Leaf nodes contain content • Attributes, Values, etc. attribute & value element & content

  13. XML is a Nested Tree - 2 Result Order@OrderId:E0001DU9 Order@OrderId#OrderState:ReadOnly Order@Items@Fruit@FruitName:Grapes|Apples Order@Items@Fruit@FruitCount:12|3

  14. XML Syntax • Tags properly nested • Tag names case-sensitive • All tags must be closed • or self-closing • <foo/> is the same as <foo></foo> • Attributes enclosed in quotes • Document consists of a single (root) element

  15. Advantages of XML • Machine-readable (easy to parse) • Standard format for data interchange • Possible to validate • Extensible • can represent any data • can add new tags for new data formats • Hierarchical structure (nesting) • Manageable with tools

  16. Alternatives in TDI for Handling XML

  17. TDI’s XML related support • Parsers • XML Sax Parser • XML DOM Parser • XSL based XML Parser • DOM Scripting with JAXP • system object methods [xslTransform()] • EMF SDO FC

  18. Using the SAX Parser XML Document Driving Code Parser Processing code (handlers) StartElement Characters etc.

  19. Using the SAX Parser -2

  20. Using the SAX Parser -3

  21. Using the SAX Parser -4

  22. Using the SAX Parser -5

  23. Using DOM XML Parser TDI DOM Parser n-Node Tree Default TDI Code performs two levels by default Custom Script to perform n level tree traversal

  24. Using DOM XML Parser -2

  25. Using DOM XML Parser -3

  26. Using DOM XML Parser -4

  27. Using DOM XML Parser -5

  28. Data persists in memory “Random access” can go forwards and backwards Can read and write In-place updates Small memory usage Does not read the whole document, just the parts needed Read only Can parse a non-well formed document DOM vs Sax

  29. Using xmldom objectto Create XML

  30. Using xmldom object -2

  31. Using xmldom object -3 <Fruit> <FruitName>Mango</FruitName> <FruitCount>12</FruitCount> </Fruit>

  32. Validating XML(example using SAX parser)

  33. XML Schemas • “Schemas” is a general term--DTDs are a form of XML schemas • When we say “XML Schemas,” we usually mean the W3C XML Schema Language • This is also known as “XML Schema Definition” language, or XSD • DTDs, XML Schemas, and RELAX NG are all XML schema languages

  34. Referring to a schema • To refer to a DTD in an XML document, the reference goes before the root element: • <?xml version="1.0"?><!DOCTYPE rootElement SYSTEM "url"><rootElement> ... </rootElement> • To refer to an XML Schema in an XML document, the reference goes in the root element: • <?xml version="1.0"?><rootElement xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"(The XML Schema Instance reference is required) xsi:noNamespaceSchemaLocation="url.xsd">(This is where your XML Schema definition can be found) ...</rootElement>

  35. Sample XML with DTD and XSD Schema XSD XML <?xml version="1.0"?> …… or …. <ste> <presenter>Lak Sri</presenter> <audience>All</audience> <topic>IDI</topic> <theme>how to</theme> </ste> <?xml version="1.0"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace=http://www.ibm.com xmlns=http://www.ibm.com elementFormDefault="qualified"> <xs:element name=“ste"> <xs:complexType> <xs:sequence> <xs:element name="presenter"type="xs:string"/> <xs:element name="audience" type="xs:string"/> <xs:element name=“topic" type="xs:string"/> <xs:element name=“theme" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> DTD <!ELEMENT ste (audience, presenter, topic, theme)> <!ELEMENT presenter (#PCDATA)> <!ELEMENT audience (#PCDATA)> <!ELEMENT topic (#PCDATA)> <!ELEMENT theme (#PCDATA)> Note: PCDATA - parsed character data

  36. Using parser for doc validation -2

  37. Using parser for doc validation -3

  38. Transforming the XML using XSL With system object

  39. Transforming the XML using XSL - 1

  40. Transforming the XML using XSL - 2 Example Output

  41. Transforming the XML using XSL - 3 XSL Transformation XML Data

  42. Transforming the XML using XSL XSL based XML Parser

  43. Transforming the XML using XSL (thru config) - 4 Result Species: Great Tinamou.| Highland Tinamou.| Little Tinamou.| Thicket Tinamou.| Slaty-breasted Tinamou.| Choco Tinamou., Family:TINAMIDAE, Order:TINAMIFORMES Species: Red-throated Loon.| Arctic Loon.| Pacific Loon.| Common Loon.| Yellow-billed Loon., Family:GAVIIDAE, Order:GAVIIFORMES

  44. EMF SDO(SDO to XML and XML to SDO)

  45. SDO in a nutshell • Self-contained object graph • Objects can be passed remotely • One API for XML and non-XML data • Generated statically-typed API can be used • DOM-like access possible Previous TDI version: SDO Technology is not available in previous versions of TDI. The EMF XMLToSDO and SDOToXML Function Components are also not compatible with the TDI 6.0 Castor Function Components. Any solution which uses the Castor Function Components needs to be re-implemented in order to work with the EMF XMLToSDO and EMF SDOToXML Function Components.

  46. SDO to XML Config

  47. SDO to XML Config Output Step 1 – Run the HTTP Server to server the XSD files referred 06:04:26 [getxml] CTGDIS505I The 'conn' object 06:04:26 [getxml] CTGDIS003I *** Start dumping Entry 06:04:26 Operation: generic 06:04:26 Entry attributes: 06:04:26 DocRoot@person#sex (replace): 'Male' 06:04:26 DocRoot@person#name (replace): 'Lak Sri' 06:04:26 [getxml] CTGDIS004I *** Finished dumping Entry 06:04:26 [getxml] CTGDIS506I The 'work' object 06:04:26 [getxml] CTGDIS003I *** Start dumping Entry 06:04:26 Operation: generic 06:04:26 Entry attributes: 06:04:26 [getxml] CTGDIS004I *** Finished dumping Entry 06:04:29 [getxml] CTGDIA012I The XML Schema has been successfully parsed and an Ecore model has been created. 06:04:29 [getxml] CTGDIA013I The Entry Attributes have been successfully applied to the data structure. 06:04:29 [getxml] CTGDIA018I The XML that results from conversion from the DOM Element to XML is: <?xml version="1.0" encoding="UTF-8"?> <person xmlns="http://www.ibm.com" sex="Male"> <name>Lak Sri</name> </person>. Step 2 – Run the AL for SDO to XML
