Lecture #7 - eXtensible Markup Language (XML)

Web Resourses:

Content:

1. The Syllabus describes topics to be covered, reading material for you to digest before coming to class, and due dates for the assigned projects.

2. Review plus one uncovered topic:

   • Collected Extension Method links:

     • Simple demo of Extension Methods

     Collected Delegate links:

     • Old and new ways to use delegates
     • Passing data along with delegate notifications - this is a new demo

     Collected Lambda links:

     • Lambda Demo
     • Lambda Capture

     Collected Reflection links:

     • Reflection Demos - reflects on test class, on delegate, and on lambda

     Presentation:

     Programming with C#, ppt
     Discusses garbage collection, Dispose(), interfaces, and other advanced topics.

3. Project Helpers:

   Project #1, Project #2
   Project2HelpF2018
   Project2HelpF16 - includes XmlHelp from 2016 Help Session
   The demos, below, were developed for Project2-F16 - a Test Harness

   They contain some relatively advanced processing, needed last year. This year we will be using Process Pools instead of AppDomains.

   • AppDomainDemo - ver 2
     Illustrates how to create a child AppDomain, load a library into it, and use the library.
     
   • AppDomainDemo2
     Illustrates how to establish two-way communication between parent and child AppDomains.
   • AppDomainDemo3
     Illustrates how to handle almost all the common processing errors, e.g.,
     test code intentionally throwing, divide by zero, use of null reference, and Thread.Abort().
   • CS-BlockingQueue
     This package implements a blocking queue, which was needed for the F2016 TestHarness.
   • LoadingTests
     Illustrates how to load test drivers, their tested code, and create and use the test driver.
   • Xml Help for TestRequests
     Illustrates how to create and parse an XML TestRequest message.
   Blog.Testing
   Find Visual Studio Command Window
   Used to test Compile.bat and Run.bat files. Substitute 2017 for 2015 in slides.

4. XML Tutorials

   W3schools - basic, University of Aarhus, XMLFiles, XML Tutorial, XML Schemas

5. XML Presentations and Demo Code:

   XML Sample, XML Sample Parse Tree

   XML Presentation, pptx XDocument - Create and Parse XML XmlHelp from earlier Help Session
   Shows how to parse a TestRequest, e.g., a non-trivial XML document. XML Demonstration Code
   This demonstrates XmlDocument, an earlier version of an XML document class.
   We won't discuss, but I left it here because you may encounter its use in C# code. XSLT Demonstration
   XSLT is a transformation language that we will discuss very briefly, but won't use in our demos and projects. XML Details Presentation
   This is a detailed XML presentation that was developed by a consultant for Microsoft.

6. Uses for XML:

   • Small databases - bug trackers, requirements models, project data
   • Representations for graphical data in Computer-Aided Design systems
   • Test data - acquiring structured data from a file, used to drive test procedures
   • Persistent data - save data generated by an analysis program for further analysis by other programs
   • Messaging - constructing structured messages for transmission over sockets or remoting channels

7. LINQ Presentation and Demos:

   IEnumerable<T> interface - MSDN link
   IQueryable<T> interface - MSDN link
   XDocument class - MSDN

   Extension Methods - used by LINQ
   Lambda Capture

   LINQ Presentation, pptx LINQ Query Examples from presentation

   LINQ Queries on Collections
   This solution contains examples of:

   • Queries on an array of ints - illustrates query syntax
   • Queries to sort an array of structs with different order specifications
   • Queries on XML, extracting various kinds of information
   • Binding XML data to a listbox in a WPF application. We won't look at this yet.

   Create XML with XDocument
   This isn't Linq, but uses some of the same .Net classes

   LINQ to SQL Example
   This solution contains:

   • Console application that programmatically creates and populates an SqlServer database
     and makes Linq queries to view its contents.
   • WPF GUI application that binds to the data in the database created by the console application,
     using a Linq query to fetch a subset of the stored information.

8. LINQ Tutorials:

   IEnumerable<T> members - MSDN link, IEnumerator<T> members - MSDN link, IQueryable<T> members - MSDN link

10. Evaluating code projects - Cyclomatic Complexity, Size, Manual and Maintenance Pages, demonstration of requirements

11. XSLT Tutorials

    XSLT is a transformation language, usually used to transform XML into HTML. We will not discuss XSLT nor use it in this course, but you should know that it exists and may find need for it in your professional work.
