Validation de grands fichiers XML

Question

Suite à mon numéro transforming large Xml files, j'ai maintenant besoin de valider le schéma.

j'utilisais cette méthode d'extension, qui peut clairement être amélioré car il est ne fonctionne pas correctement soit

public static XElement ValidateXsd(this XElement source, string xsdPath) 
{ 
    var errors = new XElement("Errors"); 

    // Reference: http://msdn.microsoft.com/en-us/library/bb358456.aspx 
    var xsd = XDocument.Load(xsdPath); 
    var xml = XDocument.Load(source.CreateReader()); 

    var schemas = new XmlSchemaSet(); 
    schemas.Add("", xsd.CreateReader()); 

    if (xml.Document != null) 
    { 
     xml.Document.Validate(schemas, 
      // Validation Event/Error Handling 
      (sender, e) => 
       { 
        var message = e.Message 
         .Replace(
          "element is invalid - The value '' is invalid according to its datatype 'requiredString' - The actual length is less than the MinLength value.", 
          "cannot be blank.") 
         .Replace(
          "is invalid according to its datatype 'size' - The Pattern constraint failed.", 
          "must be numeric.") 
         .Replace(
          "element is invalid", 
          "is invalid."); 

        errors.Add(new XElement("Error", message)); 
       } 
      ); 
    } 

    // If there were errors return them, otherwise return null 
    return errors.Elements().Count() > 0 ? errors : null; 
}

Essayez ceci:

public static XElement ValidateXsd(this XElement source, string xsdPath) 
{ 
    var errors = new XElement("Errors"); 

    // Reference: http://msdn.microsoft.com/en-us/library/bb358456.aspx 

    var schemas = new XmlSchemaSet(); 
    using (var reader = XmlReader.Create(xsdPath)) 
    { 
     schemas.Add("", reader); 
    } 

    { 
     source.Document.Validate(
      schemas, 
      // Validation Event/Error Handling 
      (sender, e) => 
      { 
       var message = 
        e.Message.Replace(
         "element is invalid - The value '' is invalid according to its datatype 'requiredString' - The actual length is less than the MinLength value.", 
         "cannot be blank.").Replace(
         "is invalid according to its datatype 'size' - The Pattern constraint failed.", 
         "must be numeric.").Replace("element is invalid", "is invalid."); 

       errors.Add(new XElement("Error", message)); 
      }); 
    } 

    // If there were errors return them, otherwise return null 
    return errors.Elements().Count() > 0 ? errors : null; 
}
