Over the last couple of months, I have been using the Ltxml.js (LINQ to XML for JavaScript) library in earnest. The project that I am working on consists of several thousand lines of JavaScript code, most of which I have hand-converted from C# to JavaScript...

This is the eleventh screen-cast in a series on writing Recursive Pure Functional Transformations of XML. This screen-cast and the following two screen-casts discuss the semantics of LINQ to XML in detail. We are going to make use of some interesting...

This is the tenth screen-cast in a series on writing Recursive Pure Functional Transformations of XML. This screen-cast and the previous screen-cast discuss the semantics of XML in detail. In order to discuss recursive pure functional transformations...

I usually like to use the Linq objects (XDpcument, XElement) when searching and modifying OpenXML documents. However, I know a lot of people prefer to use the specific objects available in version 2.0 of the SDK. For simple operations, this approach can...

This is the ninth screen-cast in a series on writing Recursive Pure Functional Transformations of XML. This screen-cast and the next screen-cast discuss the semantics of XML in detail. In order to discuss recursive pure functional transformations, it...

This is the eighth screen-cast in a series on writing Recursive Pure Functional Transformations. This screen-cast discusses functional purity. Functional purity is a must in order to write reliable, robust, debuggable, readable, and understandable functional...

This is the seventh screen-cast in a series on writing Recursive Pure Functional Transformations. This screen-cast discusses extension methods. Extension methods enable us to write queries in a more natural fashion. Return to the Table of Contents of...

This is the fifth in a series of screen-casts that will show all the ins and outs of SpreadsheetML. My goal is to present all of the most commonly used features of spreadsheets and how they are represented in SpreadsheetML. I will not be including any...

This is the sixth screen-cast in a series on writing Recursive Pure Functional Transformations. This screen-cast discusses laziness and eagerness. Understanding these concepts is key to writing transformations that perform well. Return to the Table of...

This is the fifth screen-cast in a series on writing Recursive Pure Functional Transformations. This screen-cast discusses closures, which is another of the language features that you need to understand in order to write recursive pure functional transformations...

This is the fourth screen-cast in a series on writing Recursive Pure Functional Transformations. This screen-cast discusses lambda expressions, which is one of the language features that you need to understand in order to write recursive pure functional...

For the last couple of months, I have been exploring the contents of formulas in SpreadsheetML. Formulas can include functions, cell ranges, external references, references to other sheets in the same workbook, and a variety of operators. In fact, formulas...

This is the third screen-cast in a series on writing Recursive Pure Functional Transformations. This screen-cast continues with demonstrating some rudimentary transforms, and shows more of the 'transformation operators' that you will use in a...

This is the second screen-cast in a series on writing Recursive Pure Functional Transformations. This screen-cast discusses the primary scenarios for Recursive Pure Functional Transformations. It demonstrates some rudimentary transforms, and shows a few...

This is the fourth in a series of screen-casts that will show all the ins and outs of SpreadsheetML. My goal is to present all of the most commonly used features of spreadsheets and how they are represented in SpreadsheetML. I will not be including any...
