[C＃]验证错误（XSD导入DTD） [英] [C#]Validation error (XSD importing DTD)
本文介绍了[C＃]验证错误（XSD导入DTD）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在针对链接到它的架构验证XML文件时遇到问题。我用XMLSpy和Liquid XML打开了这个文件，两者都有问题验证它。错误似乎集中在XSD结构中的特定部分，其中XSD文件导入
DTD文件。此外，许多公司已经使用了这种XML结构，这就是我不相信这是语法错误的原因。
所以这个问题的元素如下（我将发布文件和链接）：
XML测试文件：

所以当我尝试像这样读取XML文件：
XmlReaderSettings xmlReaderSettings = new XmlReaderSettings（）;
xmlReaderSettings.ValidationType = ValidationType.Schema;
xmlReaderSettings.IgnoreComments = true;
xmlReaderSettings.IgnoreWhitespace = true;
xmlReaderSettings.IgnoreProcessingInstructions = true;
xmlReaderSettings.ValidationFlags = System.Xml.Schema.XmlSchemaValidationFlags.ProcessSchemaLocation;
XmlReader reader = XmlReader.Create（" test_file.xml"，xmlReaderSettings）;
while（reader.Read（））
{}
我在XML文件的第二个元素上得到一个异常：
'urn：iso：std：iso：ts：29002：-5：ed-1：tech：xml-schema：identifier：IRDI_type'未声明，或者不是一个简单的类型
SourceUri" http：//www.eclass.eu/static/eClassXML/2.0/ontoML/identifier.xsd" （XSD1的URL）
因此，当我的程序尝试读取XSD1时，它会遇到idd：IRDI_type，它在XSD2中描述，用于导入DTD。发生了一些错误（可能是因为没有导入DTD），因此XSD2没有得到处理，因此程序没有为idt定义
：IRDI_type。
如果我在Visual Studio 2010 Web浏览器中打开XSD2，则& irdi1，& irdi2和& irdi3将替换为DTD中定义的正则表达式。所以我假设语法没问题。那么为什么我会收到验证错误？
我可以做些什么来验证XML文件？
解决方案
Hello dasiggo，
对于这个问题，我试图让有经验的人帮助你。如果我们有任何结果，我们会告诉你。
问候。
Hi,
I have a problem validating a XML file against the schema that is linked to it. I opened that file with XMLSpy and Liquid XML, and both have Problems validating it. The errors seem to center around a specific part in the XSD structure, where a XSD file imports a DTD file. Also, this XML structure is already used by many companies, that's why I don't believe that this is a syntax error.
So the elements of this Problem are as follows (I will post the files and the links):
XML test file:

Both XML Editors (XMLSpy and Liquid XML) seem to have a problem with this XSD, specifically with this part:
<xs:pattern value="&irdi1;"/>
where "&irdi1;", "&irdi2;" and "&irdi3;" are described in the imported DTD.
DTD:
<!-- Digits: 0-9 -->
<!ENTITY digit "0-9">
<!-- Internal separator character -->
<!ENTITY res ":_\.">
<!-- Alphanumeric character -->
<!ENTITY alnum "0-9A-Z">
<!-- Safe character -->
<!ENTITY safe "&alnum;&res;">

<!ENTITY ic "[&safe;]{1,131}">
<!-- Registration Authority Identifier (RAI) -->
<!ENTITY rai1 "&icd;-&oi;(-&opi;(-&opis;(-&ai;)?)?)?">
<!ENTITY rai2 "&icd;-&oi;(-&opi;)?--&ai;">

<!ENTITY irdi1 "&rai1;(#&di;#&vi;)?">
<!ENTITY irdi2 "&rai2;(#&di;#&vi;)?">
<!ENTITY irdi3 "&rai3;(#&di;#&vi;)?">So when I try to read the XML file like that:
XmlReaderSettings xmlReaderSettings = new XmlReaderSettings();
xmlReaderSettings.ValidationType = ValidationType.Schema;
xmlReaderSettings.IgnoreComments = true;
xmlReaderSettings.IgnoreWhitespace = true;
xmlReaderSettings.IgnoreProcessingInstructions = true;
xmlReaderSettings.ValidationFlags = System.Xml.Schema.XmlSchemaValidationFlags.ProcessSchemaLocation;
XmlReader reader = XmlReader.Create("test_file.xml" ,xmlReaderSettings);
while (reader.Read())
{}I get an exception on the second element of the XML file:
'urn:iso:std:iso:ts:29002:-5:ed-1:tech:xml-schema:identifier:IRDI_type' is not declared, or is not a simple type SourceUri "http://www.eclass.eu/static/eClassXML/2.0/ontoML/identifier.xsd" (The URL for XSD1)
So when my program tries to read XSD1, it encounters the idt:IRDI_type which is described in XSD2 that imports the DTD. Some error happens (probably because the DTD didn't get imported), so that XSD2 doesn't get processed, therefore the program has no definition
for idt:IRDI_type.
If I open XSD2 in Visual Studio 2010 Web Browser, &irdi1, &irdi2 and &irdi3 are replaced with regular expressions defined in the DTD. So I assume that the syntax is OK. Then why do I get a validation error?
Is there something I can do to get the XML file validated?

Hello dasiggo,
For this issue, I am trying to involve someone who is experienced with it to help you. If we have any result, we will tell you.
