Question

这里,我第一次尝试将XML与XSD验证。

XML文件有待验证:

<?xml version="1.0" encoding="utf-8" ?>
<config xmlns="Schemas" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="config.xsd">
  <levelVariant>
    <filePath>SampleVariant</filePath>
  </levelVariant>
  <levelVariant>
    <filePath>LegendaryMode</filePath>
  </levelVariant>
  <levelVariant>
    <filePath>AmazingMode</filePath>
  </levelVariant>
</config>

The XSD, based in "Schemas/config.xsd” relative to the XML file to be amended:

<?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 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>

现在,我只想像现在这样准确地验证XML文件。一旦我更好地理解这一点,我就会进一步扩大。我是否确实需要这么多条线,像现在这样简单一些?

C#中的验证法:

        public void SetURI(string uri)
        {
            XElement toValidate = XElement.Load(Path.Combine(PATH_TO_DATA_DIR, uri) + ".xml");

// begin confusion

       // exception here
       string schemaURI = toValidate.Attributes("xmlns").First().ToString() 
                              + toValidate.Attributes("xsi:noNamespaceSchemaLocation").First().ToString();
        XmlSchemaSet schemas = new XmlSchemaSet();
        schemas.Add(null, schemaURI);

        XDocument toValidateDoc = new XDocument(toValidate);
        toValidateDoc.Validate(schemas, null);
// end confusion

            root = toValidate;
        }

采用上述法典后,这一例外:

The  :  character, hexadecimal value 0x3A, cannot be included in a name.

任何照明都会受到赞赏。

http://msdn.microsoft.com/en-us/library/system.xml.linq.xdocument.validate 28v=VS.90%29.aspx”rel=“noreferer”>XDocument.Validate分机延伸方法,I将使用

public void VerifyXmlFile(string path)
{
    // configure the xmlreader validation to use inline schema.
    XmlReaderSettings config = new XmlReaderSettings();
    config.ValidationType = ValidationType.Schema;
    config.ValidationFlags |= XmlSchemaValidationFlags.ReportValidationWarnings;
    config.ValidationFlags |= XmlSchemaValidationFlags.ProcessInlineSchema;
    config.ValidationFlags |= XmlSchemaValidationFlags.ProcessSchemaLocation;
    config.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack);

    // Get the XmlReader object with the configured settings.
    XmlReader reader = XmlReader.Create(path, config);

    // Parsing the file will cause the validation to occur.
    while (reader.Read()) ;

}

private void ValidationCallBack(object sender, ValidationEventArgs vea)
{
    if (vea.Severity == XmlSeverityType.Warning)
        Console.WriteLine(
            "	Warning: Matching schema not found.  No validation occurred. {0}",
            vea.Message);
    else
        Console.WriteLine("	Validation error: {0}", vea.Message);

}

上述法典采用以下表述:

using System.Xml;
using System.Xml.Schema;

仅仅为了保持这一简单,我就没有回过<条码>boolean<>/code>或收集验证错误,你可以轻易加以修改。

注:我修改了您的《意见书》和《意见书》,使其生效。这些是我作出的改动。

config.xsd:

<xs:element maxOccurs="unbounded" name="levelVariant">

config.xml:

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="config.xsd">

以下是一份工作样本:

<><>Usage:

XMLValidator val = new XMLValidator();
if (!val.IsValidXml(File.ReadAllText(@"d:Test2.xml"), @"D:Test2.xsd"))
   MessageBox.Show(val.Errors);

<>Class>:

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 + "
";
    }

    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;
    }
}

以上代码对xsd(代码4)作以下验证。

<!--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>

在对您的xml/xsd表示反对时,我会发现与你不同的错误。

您也可以尝试反向进程;尝试从您的xml中生成图象,并与您的实际xsd进行比较——见差异;这样做的最容易的方法是利用VS IDE生成图象。下面是:

希望这一帮助。

根据John的要求,请使用未经解释的方法,查阅最新代码:

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 + "
";
}

Answer 3

你们抽取化学物位置的法典看着我们。你们为什么拿到xmlns属性的价值,并用Xsi:noNamespaceSchemaLocation属性的价值加以压缩? 造成这一例外的原因是,你无法在呼吁赞助者时规定一个先决条件;你需要具体说明所希望的XNamespace。

引证:

// Load document
XDocument doc = XDocument.Load("file.xml");

// Extract value of xsi:noNamespaceSchemaLocation
XNamespace xsi = "http://www.w3.org/2001/XMLSchema-instance";
string schemaURI = (string)doc.Root.Attribute(xsi + "noNamespaceSchemaLocation");

// Create schema set
XmlSchemaSet schemas = new XmlSchemaSet();
schemas.Add("Schemas", schemaURI);

// Validate
doc.Validate(schemas, (o, e) =>
                      {
                          Console.WriteLine("{0}", e.Message);
                      });
