Hi Ben
In response to your first question regarding XML:
- Start
Visual Studio 2005 or Visual Studio .NET.
2. Create a new Visual C# Console Application. You proceed directly to the
"Complete code listing" section or continue through these steps
to build the application.
3. Make sure that the project contains a reference to the System.Xml.dll
assembly.
4. Specify the using directive on the System.Xml namespace so that you are
not required to qualify XmlTextReader declarations later in your code. You
must use the using directive before any other declarations.
using System.Xml;
5. Create an instance of an XmlTextReader object, and populate it with the
XML file. Typically, the XmlTextReader class is used if you need to access
the XML as raw data without the overhead of a DOM; thus, the XmlTextReader
class provides a faster mechanism for reading XML. The XmlTextReader class
has different constructors to specify the location of the XML data. The
following code creates an instance of the XmlTextReader class and loads
the Books.xml file. Add the following code to the Main procedure of
Class1.
XmlTextReader reader = new XmlTextReader ("books.xml");
6. Read through the XML. (Note that this step demonstrates an outer
"while" loop, and the next two steps demonstrate how to use that
loop to read the XML.) After you create the XmlTextReader object, use the
Read method to read the XML data. The Read method continues to move
through the XML file sequentially until it reaches the end of the file, at
which point the Read method returns a value of "False."
while (reader.Read())
{
// Do some work here on the data.
Console.WriteLine(reader.Name);
}
Console.ReadLine();
7. Inspect the nodes. To process the XML data, each record has a node type
that can be determined from the NodeType property. The Name and Value
properties return the node name (the element and attribute names) and the
node value (the node text) of the current node (or record). The NodeType
enumeration determines the node type. The following sample code displays
the name of the elements and the document type. Note that this sample
ignores element attributes.
while (reader.Read())
{
switch (reader.NodeType)
{
case XmlNodeType.Element: // The node is an element.
Console.Write("<" + reader.Name);
Console.WriteLine(">");
break;
case XmlNodeType.Text: //Display the text in each element.
Console.WriteLine (reader.Value);
break;
case XmlNodeType. EndElement: //Display the end of the element.
Console.Write("");
break;
}
}
8. Inspect the attributes. Element node types can include a list of
attribute nodes that are associated with them. The MovetoNextAttribute
method moves sequentially through each attribute in the element. Use the
HasAttributes property to test whether the node has any attributes. The
AttributeCount property returns the number of attributes for the current
node.
while (reader.Read())
{
switch (reader.NodeType)
{
case XmlNodeType.Element: // The node is an element.
Console.Write("<" + reader.Name); while
(reader.MoveToNextAttribute()) // Read the attributes.
Console.Write(" " + reader.Name + "='" + reader.Value
+ "'"); Console.WriteLine(">");
break;
case XmlNodeType.Text: //Display the text in each element.
Console.WriteLine (reader.Value);
break;
case XmlNodeType. EndElement: //Display the end of the element.
Console.Write("");
break;
}
}
9. Save and close your project.
Back to the top
Complete code listing
using System;
using System.Xml;
namespace ReadXMLfromFile
{
///
/// Summary description for Class1.
///
class Class1
{
static void Main(string[] args)
{
XmlTextReader reader = new XmlTextReader ("books.xml");
while (reader.Read())
{
switch (reader.NodeType)
{
case XmlNodeType.Element: // The node is an element.
Console.Write("<" + reader.Name);
Console.WriteLine(">");
break;
case XmlNodeType.Text: //Display the text in each element.
Console.WriteLine (reader.Value);
break;
case XmlNodeType.EndElement: //Display the end of the element.
Console.Write("");
break;
}
}
Console.ReadLine();
}
}
}
