Xml classes

[dave]

Hi,

May someone tell me how can i use the C# XML classes to read an xml file?

I need to make a class with the structre of the XML files and to rean number
of xml files from the same directory and put them data in the class
represent them,
How can i read a number of xml file`s (with the same structre) to my
class???

Thanks,

Hi
one way to do that is to read them into a dataset. so if you have an xml
file that look like so
<person>
<name> first last </name>
<age> 30 </age>
<sex> M </sex>
</person>
<person>
<name> fname Lname </name>
<age> 30 </age>
<sex> F </sex>
</person>
---if the file is on root C for example, then you can read it in a dataset
this way
DataSet k = new DataSet();
k.ReadXml("c:\\ file.xml");
// the dataset now has a table with the name person that
contains all your data , so to get the age of person in second row
string name =
k.Tables["person"][1]["age"].ToStriing();

i think this is a good an effective way in your case , but there are many
other way
you can read it in an xmldocument object

example:
XmlDocument myDocument =
new XmlDocument();

myDocument.Load ("emp.xml");

Console.WriteLi ne(myDocument.I nnerXml.ToStrin g());
Console.ReadLin e();
this read the document with its structure , see this example
namespace
CSharp_XMLSampl e
{
class Class1
{
[STAThread]
static void Main(string[] args)
{
try
{
XmlDocument myDocument = new XmlDocument();
string xmlData;
myDocument.Load ("emp.xml");
int i;
int count;
count = 0;
i = 1;
XmlNode node = myDocument.Chil dNodes[1];
foreach (XmlNode node1 in node.ChildNodes )
{
Console.WriteLi ne("\n");

Console.WriteLi ne(
"The elements under node number: {0}", i);
Console.WriteLi ne(
"------------------------------------------");
foreach (XmlNode node2 in node1.ChildNode s)
{
Console.WriteLi ne(
myDocument.Docu mentElement.Fir stChild.ChildNo des

[count].Name + ": " +
node2.FirstChil d.Value);
count = count + 1;
}
i = i + 1;
count = 0;
}
Console.WriteLi ne("\n");
Console.WriteLi ne("Press <Enter> to quit...");
Console.ReadLin e();
}
catch (Exception e)
{
Console.WriteLi ne(e.Message);
Console.ReadLin e();
}
}
}
}
you can use also the xpath to find data with in document :
XmlDocument XPathDocument = new XmlDocument();
XPathDocument.L oad("emp.xml");
XPathNavigator navigator = XPathDocument.C reateNavigator( );
XPathExpression XPathExpr = navigator.Compi le("sum(//Basic/text())");
Console.WriteLi ne(navigator.Ev aluate(XPathExp r));



in fact there are many ways to do what you want , i think the dataset is
the most fast forward and it also ok with want you want to do
hope that would help

Hi dave
one little thing i forgot to mention , you need to use the System.Data
namespace to be able use dataset. other mentioned possiblities are in the
namespace System.Xml , Xpath are in System.Xml.XPat h.
