The .NET framework provides a full complement of classes for XML manipulation, which are found in the System.Xml family of namespaces (see Table 17-5). Table 17-5. XML classes in .NET
These classes offer XML-specific functionality that isn't directly available through the ADO.NET objects. For example, if you load a serialized DataSet using an XML file and XSD schema, you may not receive a warning if the XML document violates the schema; typically, you'll just lose some of the data. In cases in which you aren't sure if the XML file fits a given schema (or, in other words, you aren't sure that the data in an XML file pertains to a given table or a given version of that table), you can run through the XML file with the XmlValidatingReader before loading it into the DataSet . |
