以下是出來工作的樣品:
用法:
XMLValidator val = new XMLValidator();
if (!val.IsValidXml(File.ReadAllText(@"d:\Test2.xml"), @"D:\Test2.xsd"))
MessageBox.Show(val.Errors);
類:
public class CXmlValidator
{
private int nErrors = 0;
private string strErrorMsg = string.Empty;
public string Errors { get { return strErrorMsg; } }
public void ValidationHandler(object sender, ValidationEventArgs args)
{
nErrors++;
strErrorMsg = strErrorMsg + args.Message + "\r\n";
}
public bool IsValidXml(string strXml/*xml in text*/, string strXsdLocation /*Xsd location*/)
{
bool bStatus = false;
try
{
// Declare local objects
XmlTextReader xtrReader = new XmlTextReader(strXsdLocation);
XmlSchemaCollection xcSchemaCollection = new XmlSchemaCollection();
xcSchemaCollection.Add(null/*add your namespace string*/, xtrReader);//Add multiple schemas if you want.
XmlValidatingReader vrValidator = new XmlValidatingReader(strXml, XmlNodeType.Document, null);
vrValidator.Schemas.Add(xcSchemaCollection);
// Add validation event handler
vrValidator.ValidationType = ValidationType.Schema;
vrValidator.ValidationEventHandler += new ValidationEventHandler(ValidationHandler);
//Actual validation, read conforming the schema.
while (vrValidator.Read()) ;
vrValidator.Close();//Cleanup
//Exception if error.
if (nErrors > 0) { throw new Exception(strErrorMsg); }
else { bStatus = true; }//Success
}
catch (Exception error) { bStatus = false; }
return bStatus;
}
}
以上代碼驗證以下xml(code3)針對xsd(code4)。
<!--CODE 3 - TEST1.XML-->
<address xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Test1.xsd">
<name>My Name</name>
<street>1, My Street Address</street>
<city>Far</city>
<country>Mali</country>
</address>
<!--CODE 4 - TEST1.XSD-->
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="address">
<xs:complexType>
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="street" type="xs:string"/>
<xs:element name="city" type="xs:string"/>
<xs:element name="country" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
在驗證您的xml/xsd時,我得到的錯誤與您的不同;我想,這可以從這裏幫助你繼續(添加/刪除XML元素):

你也可以嘗試的逆過程;嘗試從你的xml生成模式,並與你的實際xsd進行比較 - 看看差異;最簡單的方法是使用VS IDE生成模式。以下是你如何做到這一點:

希望這有助於。

這是在約翰的要求,請使用非不贊成的方法看更新的代碼:
public bool IsValidXmlEx(string strXmlLocation, string strXsdLocation)
{
bool bStatus = false;
try
{
// Declare local objects
XmlReaderSettings rs = new XmlReaderSettings();
rs.ValidationType = ValidationType.Schema;
rs.ValidationFlags |= XmlSchemaValidationFlags.ProcessSchemaLocation | XmlSchemaValidationFlags.ReportValidationWarnings;
rs.ValidationEventHandler += new ValidationEventHandler(rs_ValidationEventHandler);
rs.Schemas.Add(null, XmlReader.Create(strXsdLocation));
using (XmlReader xmlValidatingReader = XmlReader.Create(strXmlLocation, rs))
{ while (xmlValidatingReader.Read()) { } }
////Exception if error.
if (nErrors > 0) { throw new Exception(strErrorMsg); }
else { bStatus = true; }//Success
}
catch (Exception error) { bStatus = false; }
return bStatus;
}
void rs_ValidationEventHandler(object sender, ValidationEventArgs e)
{
if (e.Severity == XmlSeverityType.Warning) strErrorMsg += "WARNING: " + Environment.NewLine;
else strErrorMsg += "ERROR: " + Environment.NewLine;
nErrors++;
strErrorMsg = strErrorMsg + e.Exception.Message + "\r\n";
}
用法:
if (!val.IsValidXmlEx(@"d:\Test2.xml", @"D:\Test2.xsd"))
MessageBox.Show(val.Errors);
else
MessageBox.Show("Success");
的Test2 .XML
<?xml version="1.0" encoding="utf-8" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Test2.xsd">
<levelVariant>
<filePath>SampleVariant</filePath>
</levelVariant>
<levelVariant>
<filePath>LegendaryMode</filePath>
</levelVariant>
<levelVariant>
<filePath>AmazingMode</filePath>
</levelVariant>
</config>
Test2.XSD(從VS IDE生成)
<?xml version="1.0" encoding="utf-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:element name="config">
<xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" name="levelVariant">
<xs:complexType>
<xs:sequence>
<xs:element name="filePath" type="xs:anyURI">
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
這是保證工作!
第一個答案適用於我,除了它在這裏缺少錯誤處理://解析文件將導致驗證發生。而(讀者。Read());沒有捕獲到一些錯誤(如擁有XML元素的開始,但沒有其他錯誤)。更糟糕的是,它們甚至不會在調用代碼中引發異常。 – 2012-03-12 18:12:56
