Hi,
I am trying to validate the XML that I read into a DataSet using an XML schema (xsd). However, even though the xml file is invalid, I don't get any invalid xml exception. When I print the DataSet contents, it just skips the invalid entry, which is an element named "EmailAddress". In XML schema, the element name is "Email".
I tried setting EnforceConstraints field of the dataset before reading the XML. But I think it is not related with Schema. It does not change the behavior.
Here is my code:
[code]
using System;
using System.IO;
using System.Data;
using System.Xml;
using System.Xml.Schema;
namespace Trial
{
public class Program
{
static public void Main(String[] args)
{
var myDs = new DataSet();
myDs.ReadXmlSchema("../../AddressBook.xsd");
myDs.ReadXml("../../AddressBook.xml");
myDs.AcceptChanges();
myDs.WriteXml(Console.Out);
foreach (DataTable table in myDs.Tables)
{
Console.WriteLine("Table {0} ==>", table.TableName);
foreach (DataColumn column in table.Columns)
{
Console.WriteLine("Column {0}", column.ColumnName);
}
}
}
}
}
[/code]
Here are my xml and xsd files
[code]
<?xml version="1.0"?>
<!-- 06-xml/05-schema -->
