我使用Visual StudioXML工具创建了XSD。我使用以下C#代码来验证XML并面临此错误。
错误
未声明该元素 ' http://www.w3.org/2000/09/xmldsig#:Signature'
所以我的问题是如何修复它,因为在编辑模式下,XML 100%有效?
谢谢!
C#
private void buttonValidateXML_Click(object sender, EventArgs e)
{
try

bool result = IsValidXml2(textBoxSignedXML.Text, textBoxXSDFile.Text, "");
rtbValidationResult.Text = result.ToString();
}
catch (Exception ex)
{
rtbValidationResult.Text = ex.Message;
}
}
public static bool IsValidXml2(string xmlFilePath, string xsdFilePath, string namespaceName)
{
var xdoc = XDocument.Load(xmlFilePath);
var schemas = new XmlSchemaSet();

xdoc.Validate(schemas, (sender, e) =>

更新#1
我尝试了不同的方法,但没有快乐。
即使我将XSD引用到本地文件,它也不起作用。我看到了同样的错误。
<xs:import namespace="http://www.w3.org/2000/09/xmldsig#" schemaLocation="http://www.w3.org/TR/2002/REC-xmldsig-core-20020212 file:///C:/Temp/xmldsig-core-schema.xsd"/>
更新#2
即使我使用这种方法也没有快乐。
public static bool IsValidXml1(string xmlFilePath, string xsdFilePath, string namespaceName)
{
XDocument xdoc = null;
var settings = new XmlReaderSettings();
settings.DtdProcessing = DtdProcessing.Ignore;
settings.ProhibitDtd = false;
try
{
using (XmlReader xr = XmlReader.Create(xmlFilePath, settings))
{
xdoc = XDocument.Load(xr);
var schemas = new XmlSchemaSet();
schemas.Add(namespaceName, xsdFilePath);
schemas.Add(@"http://www.w3.org/2000/09/xmldsig#", @"D:\Temp\xmldsig-core-schema.xsd");
xdoc.Validate(schemas, null);
return true;
}
}
catch (XmlSchemaValidationException ex)
{
// throw;
}
return false;
}
答案 0 :(得分:7)
如果您不想将任何内容更改为xsd或xml,请执行以下操作:
(可选)从w3 site下载xsd并保存到本地磁盘。 W3网站非常慢,因为全球许多软件都在不断地请求这些模式。如果您将直接使用该xsd - 您将经常因超时而失败。一些验证工具已经在本地缓存了这样的模式,但没有.NET验证器。
通过以下方式从UPDATE 2修改验证方法:
public static bool IsValidXml1(string xmlFilePath, string xsdFilePath, string namespaceName)
{
XDocument xdoc = null;
var settings = new XmlReaderSettings();
settings.DtdProcessing = DtdProcessing.Ignore;
try
{
using (XmlReader xr = XmlReader.Create(xmlFilePath, settings))
{
xdoc = XDocument.Load(xr);
var schemas = new XmlSchemaSet();
schemas.Add(namespaceName, xsdFilePath);
using (var fs = File.OpenRead(@"D:\Temp\xmldsig-core-schema.xsd"))
using (var reader = XmlReader.Create(fs, new XmlReaderSettings() {
DtdProcessing = DtdProcessing.Ignore // important
})) {
schemas.Add(@"http://www.w3.org/2000/09/xmldsig#", reader);
}
xdoc.Validate(schemas, null);
return true;
}
}
catch (XmlSchemaValidationException ex)
{
// throw;
}
return false;
}
您必须使用XmlReader
而不是直接添加该架构,因为如果您直接添加(如更新2中) - 它将无法解析DTD块,因为当您添加XmlSchema
时XmlSchemaSet
使用网址(或文件路径) - 它会使用XmlReaderSettings
DtdProcessing = DtdProcessing.Prohibit
来读取该文件。我们需要将其更改为DtdProcessing.Ignore
或DtdProcessing.Parse
。之后,您的验证方法将适用于目标xsd和xml文件,无需任何更改(如果xml与xsd不匹配,则会正确失败)。
答案 1 :(得分:6)
你非常接近。在您的XSD中,只需替换,
<xs:import namespace="http://www.w3.org/2000/09/xmldsig#" />
与
<xs:import namespace="http://www.w3.org/2000/09/xmldsig#"
schemaLocation=
"http://www.w3.org/TR/2002/REC-xmldsig-core-20020212/xmldsig-core-schema.xsd"/>
并且您的XSD将不再出现该错误,并且您的XML将对您的XSD有效。
XSD可以通过xs:import
and xs:include
撰写。在这两种情况下,必须使用必需的schemaLocation
属性指定引用的XSD的位置,该属性在OP的原始XSD中缺失。通过如上所示添加xs:import/@schemaLocation
,可以消除错误。
当您切换为使用本地XSD时,您在xs:import
:
更改
<xs:import namespace="http://www.w3.org/2000/09/xmldsig#"
schemaLocation="http://www.w3.org/TR/2002/REC-xmldsig-core-20020212
file:///C:/Temp/xmldsig-core-schema.xsd"/>
到
<xs:import namespace="http://www.w3.org/2000/09/xmldsig#"
schemaLocation="file:///C:/Temp/xmldsig-core-schema.xsd"/>
(您在XML文档中关注@xsi:schemaLocation
的示例,该文档具有命名空间位置对; xs:import/@schemaLocation
不同。)
所以我的问题是如何修复它,因为在编辑模式下,XML 100%有效?
也许这就是脱节。在Visual Studio中编辑XML文件不会自动根据XSD对其进行验证。您需要在代码中或通过验证XML编辑器执行此操作,例如Oxygen XML Editor或XML Spy。
此外,您的C#验证码可能存在问题。见Validating an XML against referenced XSD in C#
