xsd操作

1.xsd介绍

详见: http://blog.sina.com.cn/s/blog_ad0672d60102uy6w.html

2.生成xsd

DataSet dataSet = new DataDet();

// read date from xml file

dataSet.ReadXml(@"xml2.xml", XmlReadMode.ReadSchema);

// .. or set data with code

// save as xsd file

System.IO.StreamWriter writer = new System.IO.StreamWriter("Customers.xsd");

dataSet.WriteXmlSchema(writer);

writer.Close();

// get xsd format contents

string schemaString = dataSet.GetXmlSchema();

// save as xml

dataSet.WriteXml(@"xml2_new.xml", XmlWriteMode.WriteSchema);

3.由xsd生成xml

xsd.exe工具可生成操作的cs类，再有生成的cs类生成xml文件

4.xsd检验xml

using System.Xml;        // for XmlTextReader and XmlValidatingReader

using System.Xml.Schema; // for XmlSchemaCollection (which is used later)

private static bool isValid = true;      // If a validation error occurs,

                                         // set this flag to false in the

                                         // validation event handler. 

XmlTextReader r = new XmlTextReader("ProductWithXSD.xml");

XmlValidatingReader v = new XmlValidatingReader(r);

v.ValidationType = ValidationType.Schema;

v.ValidationEventHandler += new ValidationEventHandler(MyValidationEventHandler);

while (v.Read())

{

   // Can add code here to process the content.

}

v.Close();

// Check whether the document is valid or invalid.

if (isValid)

   Console.WriteLine("Document is valid");

else

   Console.WriteLine("Document is invalid");

   

public static void MyValidationEventHandler(object sender, 

                                            ValidationEventArgs args) 

{

   isValid = false;

   Console.WriteLine("Validation event " + args.Message);

}

// 另一种方法

XDocument xDoc = XDocument.Parse(xxxxxxx);

string xsdPath = ConfigUtils.GetXsdPath(XsdSchemaIdentifier.HHDataItem);

XmlSchemaSet xss = new XmlSchemaSet();

xss.Add("", xsdPath);

fs.Close();

fs.Dispose();

xDoc.Validate(xss, null);
