Lecture Description
XML Processing and Python - Two Different XML Processing Models, Example XML Fragment, How an XML Parser Uses Tag Handlers to Break Up an XML Stream, How Python Can Parse XML Streams Using Urlopen, Make_Parser, and Contenthandler, Defining a Listfeedtitles Function that Takes in a URL and Parses it Using a Parser and an Rsshandler, Contenthandler Interface, Implementing The Rsshandler Class, Which Subclasses Contenthandler, to Fit The Specific Goals of The RSS Feed Reader, Implements The Rsshandler So that it Only Prints Data that Lies Within a Title Tag, Looking at an Actual RSS Feed in Firefox and Through Telnet, Looking at an XML Document with a Tree-Based XML Renderer Rather Than a Stream-Based Parser, Advantages of this Approach
Course Description
Topics include: Advanced memory management features of C and C++; the differences between imperative and object-oriented paradigms; the functional paradigm (using LISP) and concurrent programming (using C and C++); brief survey of other modern languages such as Python, Objective C, and C#. Prerequisites: Programming and problem solving at the Programming Abstractions level. Prospective students should know a reasonable amount of C++. You should be comfortable with arrays, pointers, references, classes, methods, dynamic memory allocation, recursion, linked lists, binary search trees, hashing, iterators, and function pointers. You should be able to write well-decomposed, easy-to-understand code, and understand the value that comes with good variable names, short function and method implementations, and thoughtful, articulate comments.
