Microsoft's counterpiece to Java, the new C# programming language with its rich .NET library, uses XML as a core technology. This article presents some basic ideas, for example creating and manipulating a DOM tree, and reading and writing XML streams. I also compare .NET's solution with the SAX model, and finally I show how a complex XSLT algorithm can be more simply implemented in C#. The source code can be downloaded from and www.sys-con.com/xml/sourcec.cfm. XML Processors To process an XML document means to extract information from it. Often the extracted information should be output to a new XML (or perhaps HTML) document that's similar to the original one - then we address the transformation. Which processor to use for a given task is not a trivial question. There are a number of ready-to-use XML processors on the market - like Cocoon and Axkit - and any XML-e... (more)

Aggregation with XMLSPY

Aggregation in XML is not trivial. Altova's XMLSPY offers a number of features facilitating this process. This article presents an example, including best practices and practical programming techniques - especially useful for those who don't like typing a lot of angle brackets. Aggregation of XML (or HTML) documents means to collect the content of several XML files in one XML (or HTML) document (see Figure 1). A portal product, for example, would aggregate the content of several data sources into one HTML page and present their contents in boxes in the user's browser. Most portal... (more)
