紧急求助！如何用VB编程验证xml文件有效性
如题，我想验证一个XML文件是否有效，比如说想关节点名称是否对应，是否存在非法字符 --------------------编程问答-------------------- XmlValidatingReader Sample CodeI had to work up a sample of the XmlValidatingReader for a coworker, so I though I'd share it with everyone. Here is a quick example of using the XmlValidatingReader. There are other ways to construct/use it, but this is the most common method around here. Hope this helps someone.
using System;
using System.IO;
using System.Xml;
using System.Xml.Schema;
namespace ConsoleApplication1
{
class Class1
{
[STAThread]
static void Main(string[] args)
{
// path's to xml/xsd
const string path = @"C:\Projects\PSLL\ConsoleApplication1";
const string xmlPath = path + @"\franchise_detail.xml";
const string xsdPath = path + @"\Program.xsd";
// Create a new validating reader
XmlValidatingReader reader = new XmlValidatingReader(new XmlTextReader(new StreamReader(xmlPath)));
// Create a schema collection, add the xsd to it
XmlSchemaCollection schemaCollection = new XmlSchemaCollection();
schemaCollection.Add("http://detail.franchise.scarlett",xsdPath);
// Add the schema collection to the XmlValidatingReader
reader.Schemas.Add(schemaCollection);
Console.Write("Validating....");
// Wire up the call back. The ValidationEvent is fired when the
// XmlValidatingReader hits an issue validating a section of the xml
reader.ValidationEventHandler += new ValidationEventHandler(reader_ValidationEventHandler);
// Iterate through the xml document
while(reader.Read())
{
Console.Write(".");
}
Console.WriteLine("\n");
Console.ReadLine();
}
private static void reader_ValidationEventHandler(object sender, ValidationEventArgs e)
{
// Report back error information to the console...
Console.WriteLine("Bad stuff happened");
Console.WriteLine(e.Exception.Message);
Console.WriteLine(e.Exception.LineNumber);
}
}
}
--------------------编程问答-------------------- 对于如何创建xml schema，也就是XSD文件。
参见下面的文章

补充：.NET技术 , Web Services
