System.Xml.XmlException：该元素不能包含空格。内容模型为空

我正在使用 Dtd 来验证从用户那里收到的 xml 字符串，但我不断收到此异常：

System.Xml.XmlException: The element cannot contain white space. 
Content model is empty. ---> System.Xml.XmlException: 
The element cannot contain white space. Content model is empty.
---> System.Xml.Schema.XmlSchemaException: 
The element cannot contain white space. Content model is empty.

如何从 XML 字符串中删除那些无效的空白字符？

过去3个小时我一直在为此苦苦挣扎。

这是我编写的用于进行 DTD 验证的方法：

public static void Validate(string xmlToValidate, string documentType, string dtd)
    {
        try
        {
            Check.Argument.IsNotNullOrEmpty(documentType, "documentType");
            Check.Argument.IsNotNullOrEmpty(xmlToValidate, "xmlToValidate");
            Check.Argument.IsNotNullOrEmpty(dtd, "dtd");


            //clean the xml
            string xml = SanitizeXml(xmlToValidate);

            XmlDocument xmlDoc = new XmlDocument();

            //append the dtd to the xml doc
            XmlDocumentType docType = xmlDoc.CreateDocumentType(documentType, null,      null, dtd);
            xmlDoc.AppendChild(docType);

            var xmlDeclaration = xmlDoc.CreateXmlDeclaration("1.0", null, null);

            xmlDoc.InsertBefore(xmlDeclaration, docType);

            xml = RemoveDeclaration(xml);

            //Append XML to the Xml Doc
            xmlDoc.AppendXml(xml);

            XmlReaderSettings settings = new XmlReaderSettings();
            settings.DtdProcessing = DtdProcessing.Parse;
            settings.ValidationType = ValidationType.DTD;

            settings.ValidationEventHandler += (sender, e) =>
            {
                throw new XmlException(e.Message, e.Exception);
            };

            StringWriter stringWriter = new StringWriter();

            //save the xmlDoc content to the writer
            xmlDoc.Save(stringWriter);

            XmlReader rdr = XmlReader.Create(new StringReader(stringWriter.ToString    ()), settings);

            //Parse the xml to check DTD conformance
            while (rdr.Read()) ;

            //Close
            rdr.Close();
        }
        catch (Exception ex)
        {
            XmlException e = new XmlException(ex.Message, ex);
            throw e;
        }

    }Here's the string I'm testing with (but I'll be receiving it from external source) :

public const string XmlEMSOrder = @"<?xml version='1.0' encoding='utf-8' ?>
<Root>
  <OrderInformation>
    <Project>
      <ProjName>Project name </ProjName>
      <ContactName>Proj Contact </ContactName>
      <Phone>Proj Phone</Phone>
      <PONo>Project End User PO</PONo>
      <ProjectNo>Project# </ProjectNo>
      <RSPNo>Quote Trent</RSPNo>
      <SalesmanName>SalesFN1 SalesLN1</SalesmanName>
      <Salesman2Name>SalesFN2 SalesLN2</Salesman2Name>
      <Salesman3Name />
      <ACPONo>AC PO Number</ACPONo>
      <NationalAccountAgreement>1</NationalAccountAgreement>
      <Agreement />
      <AccountType />
      <HealthCare />
      <Government />
      <Other />
      <GovAccount>1</GovAccount>
       ....

这是我使用的 Dtd：

I am using Dtd to validate an xml string I receive from users, and I keep getting this exception :

System.Xml.XmlException: The element cannot contain white space. 
Content model is empty. ---> System.Xml.XmlException: 
The element cannot contain white space. Content model is empty.
---> System.Xml.Schema.XmlSchemaException: 
The element cannot contain white space. Content model is empty.

How to remove those invalid white space characters from an XML string ?

I've been struggling with this for the past 3 hours.

Here's the method I wrote to do DTD validation :

public static void Validate(string xmlToValidate, string documentType, string dtd)
    {
        try
        {
            Check.Argument.IsNotNullOrEmpty(documentType, "documentType");
            Check.Argument.IsNotNullOrEmpty(xmlToValidate, "xmlToValidate");
            Check.Argument.IsNotNullOrEmpty(dtd, "dtd");


            //clean the xml
            string xml = SanitizeXml(xmlToValidate);

            XmlDocument xmlDoc = new XmlDocument();

            //append the dtd to the xml doc
            XmlDocumentType docType = xmlDoc.CreateDocumentType(documentType, null,      null, dtd);
            xmlDoc.AppendChild(docType);

            var xmlDeclaration = xmlDoc.CreateXmlDeclaration("1.0", null, null);

            xmlDoc.InsertBefore(xmlDeclaration, docType);

            xml = RemoveDeclaration(xml);

            //Append XML to the Xml Doc
            xmlDoc.AppendXml(xml);

            XmlReaderSettings settings = new XmlReaderSettings();
            settings.DtdProcessing = DtdProcessing.Parse;
            settings.ValidationType = ValidationType.DTD;

            settings.ValidationEventHandler += (sender, e) =>
            {
                throw new XmlException(e.Message, e.Exception);
            };

            StringWriter stringWriter = new StringWriter();

            //save the xmlDoc content to the writer
            xmlDoc.Save(stringWriter);

            XmlReader rdr = XmlReader.Create(new StringReader(stringWriter.ToString    ()), settings);

            //Parse the xml to check DTD conformance
            while (rdr.Read()) ;

            //Close
            rdr.Close();
        }
        catch (Exception ex)
        {
            XmlException e = new XmlException(ex.Message, ex);
            throw e;
        }

    }Here's the string I'm testing with (but I'll be receiving it from external source) :

public const string XmlEMSOrder = @"<?xml version='1.0' encoding='utf-8' ?>
<Root>
  <OrderInformation>
    <Project>
      <ProjName>Project name </ProjName>
      <ContactName>Proj Contact </ContactName>
      <Phone>Proj Phone</Phone>
      <PONo>Project End User PO</PONo>
      <ProjectNo>Project# </ProjectNo>
      <RSPNo>Quote Trent</RSPNo>
      <SalesmanName>SalesFN1 SalesLN1</SalesmanName>
      <Salesman2Name>SalesFN2 SalesLN2</Salesman2Name>
      <Salesman3Name />
      <ACPONo>AC PO Number</ACPONo>
      <NationalAccountAgreement>1</NationalAccountAgreement>
      <Agreement />
      <AccountType />
      <HealthCare />
      <Government />
      <Other />
      <GovAccount>1</GovAccount>
       ....

Here is the Dtd I use :

在 DTD 中，我将 : 切换

<!ELEMENT characteristics EMPTY >

为 :

<!ELEMENT characteristics ANY >

这是 xml 的相关部分：

 <characteristics></characteristics>

in the DTD, I switched this :

<!ELEMENT characteristics EMPTY >

to :

<!ELEMENT characteristics ANY >

this is the portion of the xml concerned :

 <characteristics></characteristics>
