When you run the Web Services Description Language tool (Wsdl.exe) in Microsoft Visual Studio .NET to create an XML Web service proxy for the .NET Framework remoting service that contains either a Char data type member or a Guid data type member, you may receive an error message that is similar to t

(Rick Jelliffe) I taught a couple of full day courses last week, on XSLT and XML Schemas. The students were pretty positive banking programmers, and I only managed to disgrace myself once, when I became stroppy at a student I misheard: he was trying to be helpful, but I thought he was insanely and r

(Peter G. Aitken) .NET provides a powerful set of classes for working with XML directly. This article provides an overview of the most important of these classes, and some examples of what you can do with them.

(Paul Ford) A peculiar buzz is back in the halls of WWW2004 — the mix of hubris and geek name dropping, cheap suits and over-eager handshakes that last prevailed in 2000. “I nearly invented the web,” says a fellow with a large stack of promotional postcards advertising new social networking softwar

(Kendall Grant Clark) We’ve followed Atom — the community-driven XML vocabulary and protocol API for web resource syndication — on XML.com since it was first announced. In fact, I suspect that we’ve published as much about Atom, including columns by Mark Pilgrim and Joe Gregorio, as any other web

(Uche Ogbuji) When designing XML and Web services schemata you will often (and ideally) reuse data elements defined in pre-existing standards. When you do, it is extremely useful to include links to such standards, providing precise data dictionary references. In so doing, you make processing and ma

(Arulazi Dhesiaseelan) The W3C’s Web Services Description Working Group, part of the Web Services Activity, has defined a language for describing web services and the possible ways to interact with them. The WG published its WSDL 2.0 working drafts on 26 March 2004. This is a significant milestone i

(Kevin Ruse) No doubt, you have heard about XML. XML is everywhere. For Web designers, that can add to the confusion. If something is everywhere, it’s nowhere. If only you heard “XML is the new HTML,” then maybe you could wrap your mind around it as a markup language. But chances are, you’ve hea

(Jimmy Zhang) Text processing is one of the most common tasks in application development. Whether it is a Java Servlet or a VOIP application, the conversion from a raw text-based input message to a machine-readable internal representation almost always requires parsing (or tokenization), which, in i

(Daniel Cazzulino) Learn the difference between typed datasets and classes generated by the xsd.exe tool, as well as how to extend this code generation process by reusing the infrastructure classes supporting it, while remaining compatible with the XmlSerializer.
