Some great stuff going on with XML lately.  Jan Tielens shows how to use InfoPath to access a secondary datasource, such as a SharePoint list Matt Warren then delves into some XML bestiary and shows a binary XML parser based on XmlReader.  Cazz (the one and only avid bathreader) shows how to iterate over XPathNodeIterator nodes, ...

Ever wonder if there is an XML Schema for the msdata namespace (urn:schemas-microsoft-com:xml-msdata) used by the DataSet generation wizard?  You can find it here.

Someone asked me about using a typed DataSet on both ends of the wire using a web service. I honestly don't work with typed DataSets, but this question was to accomodate the client's existing architecture. We both tried it, and couldn't get it to work.

Paul Wilson emailed me with some questions regarding perceived memory leaks related to System.Xml.Serialization.XmlSerializer.  I questioned whether it would be a “memory leak”, but pinged Christoph Schittko for some backup evidence.  He said he doubted it as well, else web services everywhere would be falling on their faces.  I ...
