  1. XML, Xpath and XSLT Greg Alvord Senior Data Architect, RealEC David Krause AVP, Radian Guaranty June 4, 2012

  2. Agenda • Overview • Xpath • XSLT • Real World Scenarios • Background on system layout • Routing rules • Translation between two defined formats • Avoid system customization • Prevent semantic loss

  3. Overview • Xpath • Syntax for defining individual pieces of an XML document using path-based expressions • Allows for navigating through XML document and applying collection of built-in functions

  4. Overview • XSLT • EXtensible Stylesheet Language Transformation • XSLT is used to transform an XML document into another XML document, or another type of document that is recognized by a browser, like HTML and XHTML • Can add/remove elements and attributes to/from the appropriate output file • Sort • Perform calculations/logic • XML navigation based on XPath

  5. Message Routing for Generic Endpoints • Generic endpoint for all Origination transactions • Rely on either message level or payload level information to route accordingly

  6. Message Routing for Generic Endpoints

  7. Translation Between Formats • Convert external standard format to internal to be consumed by downstream application • Logic can be simple 1-to-1 mapping OR more complex If…Then or Choice logic

  8. Translation Between Formats

  9. Translation Between Formats

  10. Avoid Application Customization • Often times a trading partner will not adhere to all integration requirements • Ideal to isolate these “one-offs” • Prevent from leaking into the base application • Execute a pre-process translation to clean up the XML

  11. Avoid Application Customization

  12. Avoid Losing Message Granularity/Relevance • Internal organization requirements vs. trading partner requirement may result in conflict • Similar to avoiding application customization, can place translation right before message leaves network

  13. Avoid Losing Message Granularity/Relevance
