XmlDocument Class

Represents an XML document.

Namespace: System.Xml
Assembly: System.Xml (in system.xml.dll)

public class XmlDocument : XmlNode
public class XmlDocument extends XmlNode
public class XmlDocument extends XmlNode

This class implements the W3C Document Object Model (DOM) Level 1 Core and the Core DOM Level 2. The DOM is an in-memory (cache) tree representation of an XML document and enables the navigation and editing of this document. Because XmlDocument implements the IXPathNavigable interface it can also be used as the source document for the XslTransform class.

The XmlDataDocument class extends XmlDocument and allows structured data to be stored, retrieved, and manipulated through a relational DataSet. This class allows components to mix XML and relational views of the underlying data.

See XML Document Object Model (DOM) for more information.

Exceptions raised as a result of using the XmlDocument class, such as the XmlException class may contain sensitive information that should not be exposed in untrusted scenarios. Exceptions should be properly handled so that this sensitive information is not exposed in untrusted scenarios.

How to read XMLNode from a XML Document.

Here is some sample XML we want to read:

<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="Path" value="C:\DATA\Blitz\BlitzTest" />
<add key="SourcePath" value="C:\toolbox\Visual Studio 2005\Projects\Blitz Reporting\Blitz Reporting\" />
</appSettings>
</configuration>

'

Here is some sample VB code that shows you how to read these nodes.

Dim XMLDoc AsNew Xml.XmlDocument 
XMLDoc.Load("web.config") 'xml file you want to load
Dim node As Xml.XmlNode = XMLDoc.SelectSingleNode("/configuration/appSettings") 'node path
Dim Path AsString = node.ChildNodes(0).Attributes("value").Value 
Dim SourcePath AsString = node.ChildNodes(1).Attributes("value").Value 

'

As you can guess the values look like the following:

Path = "C:\DATA\Blitz\BlitzTest"
SourcePath = "C:\toolbox\Visual Studio 2005\Projects\Blitz Reporting\Blitz Reporting\"
Table Example
I believe that what the XML documentation is lacking at the moment is an example of how an XML document can be used as a table in lieu of a table in a database. An example would include the CRUD model showing an XML document being handled as a table. I am working on this to place here. If you have any current examples please place them here.
