问题描述
我使用Visual StudioXML工具创建了XSD.而且我使用以下C#代码验证XML并遇到此错误.
错误
So my question is how to fix it because in edit mode XML is valid 100%?
Thank you!
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();
schemas.Add(namespaceName, xsdFilePath);
bool result = true;
xdoc.Validate(schemas, (sender, e) =>
{
result = false;
});
return result;
}

UPDATE #1
I have tried different approaches but no joy.
And even if I reference XSD to local file it does not work. I see the same error.
<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"/>
UPDATE #2
Even I use this approach no joy.
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;
}
If you don't want to change anything to xsd or xml - do the following:
(optional) Download xsd from w3 site and save to local disk. W3 site is VERY slow because a lot of software worldwide constantly request those schemas. If you will use that xsd directly - you will often fail by timeout. Some validation tools already have such schemas cached locally, but not .NET validator.
Modify your validation method from UPDATE 2 the following way:
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; }
You have to add that schema using XmlReader
and not directly, because if you add directly (like in your update 2) - it will fail to parse DTD block, because when you add XmlSchema
to XmlSchemaSet
using url (or file path) - it will read that file using XmlReaderSettings
with DtdProcessing = DtdProcessing.Prohibit
. We need to change that to DtdProcessing.Ignore
or DtdProcessing.Parse
. After that your validation method will work fine for target xsd and xml file, without any changes (and will correctly fail in case xml does not match xsd).
