[英]XML schema validation results “Attribute not declared”
I validate an XML document against my XML schema. 我根据我的XML模式验证了XML文档。 I recently added a new attribute in the XML files and the XSD schema.
我最近在XML文件和XSD架构中添加了一个新属性。 But when doing the validation I always get an exception
但是在进行验证时,我总是会遇到异常
base{System.EventArgs}: {System.XML.Shema.ValidationEventArgs}
base {System.EventArgs}:{System.XML.Shema.ValidationEventArgs}
Exception: "The Anhaenger-Attribute is not declared.例外:“未声明Anhaenger属性。
Message: "The Anhaenger-Attribute is not declared.消息:“未声明Anhaenger属性。
Here the declaration in my XSD schema: 这是我的XSD模式中的声明:
<xs:attribute id="Anhaenger" name="Anhaenger" use="optional">
<xs:simpleType>
<xs:restriction base="D2TAnhaenger_Type" />
</xs:simpleType>
</xs:attribute>
<xs:simpleType id="D2TAnhaenger_Type" name="D2TAnhaenger_Type">
<xs:restriction base="xs:string">
<xs:maxLength value="70" />
<xs:whiteSpace value="collapse" />
</xs:restriction>
</xs:simpleType>
and this is the attribute in the XML file: 这是XML文件中的属性:
Anhaenger="ANH - 0815"
Here the code I use for doing the correction in my application: 这是我用于在应用程序中进行更正的代码:
protected XmlDocument ValidateAndCorrect(Stream XMLStream)
{
// Verwenden von XMLReader, damit die Schemainformationen an den Knoten angefügt werden.
// Dann können wir später korrigieren.
XmlReaderSettings settings = new XmlReaderSettings();
settings.Schemas.Add("", m_SchemaFile);
settings.ValidationEventHandler += new ValidationEventHandler(ValidationEventHandler);
settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessInlineSchema;
settings.ValidationType = ValidationType.Schema;
// Dokument aus dem Stream holen.
XmlDocument document = new XmlDocument();
XMLStream.Seek(0, SeekOrigin.Begin);
XmlReader reader = XmlReader.Create(XMLStream, settings);
document.Load(reader);
int i = 0;
bool validate = true;
while (validate)
{
i++;
Debug.WriteLine("--- Validierung und Korrektur beginnt ---");
Debug.WriteLine("Durchlauf Nummer: " + i.ToString());
m_errors = new List<ValidationEventArgs>();
document.Validate(this.ValidationEventHandler);
validate = CorrectValidationResult(document.ChildNodes);
}
return document;
}
So, does anyone have an idea what I do wrong? 那么,有人知道我做错了什么吗? Many thanks for any help
非常感谢您的帮助

The catch is in the target namespace of your XSD; 捕获位于XSD的目标名称空间中。 I guess (you're not showing the xs:schema attribute set) that since your XML attribute is declared global, it must be prefixed with an alias which matches your schema's targetNamespace.
我猜(您没有显示xs:schema属性集),由于XML属性被声明为全局属性,因此必须在前缀之前添加一个与架构的targetNamespace相匹配的别名。
