XmlDocument Class

Represents an XML document.

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

Syntax

Visual Basic (Declaration)

Public Class XmlDocument
    Inherits XmlNode

Visual Basic (Usage)

Dim instance As XmlDocument

public class XmlDocument : XmlNode

C++

public ref class XmlDocument : public XmlNode

public class XmlDocument extends XmlNode

Remarks

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.

Security Note
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.

Brent30 ... Thomas Lee | Edit | Show History

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\"
