C # uses XSD files to verify that the XML is properly formatted

Method One:

I use XmlReader to deal with it because I feel XmlReader simple point.

I have made an example to illustrate that the XML in the example is not very complex and has no child nodes.

XML file (a.xml):

<?XML version= "1.0" encoding= "Utf-8"?>< Profile>  <profileID>0001</profileID>  <desciption>My content</desciption>  <URL><! [Cdata[http://www.bclc.com/app/DidYouWin/WinningNumbers/Lotto649Print.asp? Year=2000&month=6&draw_date=&gameid=1]]></URL>  <NUMBERS>6</NUMBERS>  <BONUS>True</BONUS></ Profile>

xsd file (a.xsd):

<?XML version= "1.0" encoding= "utf-16"?><Xsd:schemaattributeFormDefault= "unqualified"elementFormDefault= "qualified"version= "1.0"xmlns:xsd= "Http://www.w3.org/2001/XMLSchema">  <xsd:elementname= "Profile">    <Xsd:complextype>      <xsd:sequence>        <xsd:elementname= "profileID"type= "Xsd:int" />        <xsd:elementname= "Desciption"type= "Xsd:string" />        <xsd:elementname= "URL"type= "Xsd:string" />        <xsd:elementname= "NUMBERS"type= "Xsd:int" />        <xsd:elementname= "BONUS"type= "Xsd:boolean" />      </xsd:sequence>    </Xsd:complextype>  </xsd:element></Xsd:schema>

C # uses XSD files to verify that the XML format is correct:

XmlReaderSettings st =Newxmlreadersettings (); XmlSchemaSet Schemaset=NewXmlSchemaSet (); Schemaset.add (NULL, spath);//St. ValidationEventHandler + = new ValidationEventHandler (ValidationEventHandler);St. Validationflags = St. Validationflags |xmlschemavalidationflags.reportvalidationwarnings;st. ValidationType=validationtype.schema;st. Schemas.add (Schemaset,@"a.xsd"); //sets the event to validate XML when an error occurs. St. ValidationEventHandler + = (obj, e) =>{//this adds to your information processing. }; XmlReader XR = xmlreader.create (@"A.xml", ST);  while(XR. Read ()) {if(XR. Isstartelement () {XR. Read (); }} XR. Close ();

Method Two:

//Create XmlDocumentXmlDocument doc =NewXmlDocument (); //create a declaration segment such as <?xml version= "1.0" encoding= "Utf-8"?>Doc. AppendChild (Doc. Createxmldeclaration ("1.0","Utf-8",NULL)); //Create a root node kytresultsXmlElement results = doc. CreateElement ("Kytresults"); //Create ResultsstatusXmlNode resultsstatus = doc. CreateElement ("Resultsstatus"); //Create levelXmlElement element = doc. CreateElement (" Level"); Element. InnerText= status?"0":"1";                 Resultsstatus.appendchild (Element); //Create Descriptionelement = Doc. CreateElement ("Description"); Element. InnerText=msg;                 Resultsstatus.appendchild (Element); //Create passkey If user logon failure will load null characterselement = Doc. CreateElement ("passkey"); Element. InnerText=key;                 Resultsstatus.appendchild (Element); Results.                 AppendChild (Resultsstatus); //END Create Resultsstatus//Create DataList data collection                if(status) {results.                 AppendChild (dataList); }                 //END creates a root node KytresultsDoc.                       AppendChild (results); stringPath = Server.MapPath ("/ws/xsd/receivereturn.xsd"); //verifying that the XML format is correctly validated by XSD                    stringError =""; //Statement XmlSchemaXmlSchemaSet schemas =NewXmlSchemaSet (); Schemas. ADD ("", Xmlreader.create (path)); //declaring event handling methodsValidationEventHandler EventHandler =NewValidationEventHandler (Delegate(Objectsender, ValidationEventArgs e) {                         Switch(e.severity) { CaseXmlSeverityType.Error:error+=E.message;  Break;  Casexmlseveritytype.warning: Break;                     }                     }); Doc. Schemas=schemas; //Validating XMLDoc.                     Validate (EventHandler); //Check for an exception if the format is incorrect, throw it out.                    if(!"". Equals (Error)) {Throw NewException (Error); }
