Xml Validation Error -> Automatically entered extra character

[sekarm]

Hi there,
Hi Everybody, I am facing one problem to validate the xml file. first i load the xml file through XmlDocumentType Class. Before load the Xml file i add the code xmlresolver = null for not validating DTD. Then i get one particular node through getElementBytag name method. After find out the node i have add the attribute fot the node. then i save the xml file in particular path through xmldocumenttype .save() method. After i open the xml file the extra charater that is [] added at end of the DTD. After that i check the xml file through some other check, it throwns a error on special characte [] is added in end of dtd. i dont know when was the special character [] is added in dtd.
i am using C#.Net 2005. All process are done through XMLDocument class.
Please give me the solution.

Thanks In Advance,
Sekar.M

Dear Dorin,
Thank you for your quick reply. please find the xml file and code i attached.

The Xml File is
The file name is sample.xml

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE note SYSTEM "note.dtd">
<ZooRoot>
  <ZooTable Name="Crazy Zoo" Address="32 Turtle Lane" City="Austin" State="TX" Zip="12345">
    <Classification Type="Reptiles" />
    <Classification Type="Birds" />
    <Classification Type="Primates" />
  </ZooTable>
  <ZooTable Name="Chicago Zoo" Address="23 Zebra Ave" City="Chicago" State="IL">
    <Classification Type="Fish" />
    <Classification Type="Mammals" />
    <Classification Type="Primates" />
  </ZooTable>
  <ZooTable Name="Hungry Zoo" Address="45 Lion st" City="Miami" State="FL" Zip="33122">
    <Classification Type="Arachnids" />
    <Classification Type="Rodents" />
  </ZooTable>
</ZooRoot>

I have modified the above xml file through below this code,

using System.xml;
XmlDocument Doc = new XmlDocument();
            Doc.XmlResolver = null;
            Doc.Load(@"E:\sample.xml");
            XmlNodeList RootNode = Doc.GetElementsByTagName("Classification");
            foreach (XmlNode filesnode in RootNode)
            {
                //.ChildNodes[0].RemoveAll();
                filesnode.RemoveAll();
 
                XmlNode createnode = Doc.CreateElement("Animal");
                XmlAttribute attr = Doc.CreateAttribute("AnimalName");
                attr.Value = "Lion";
                createnode.Attributes.SetNamedItem(attr);
                // Creat Attribute For New Node
                filesnode.AppendChild(createnode);
            }
            Doc.Save(@"E:\sample.xml");

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE note SYSTEM "note.dtd"[]> 
        
                note it []
 
 
<ZooRoot>
  <ZooTable Name="Crazy Zoo" Address="32 Turtle Lane" City="Austin" State="TX" Zip="12345">
    <Classification>
      <Animal AnimalName="Lion" />
    </Classification>
    <Classification>
      <Animal AnimalName="Lion" />
    </Classification>
    <Classification>
      <Animal AnimalName="Lion" />
    </Classification>
  </ZooTable>
  <ZooTable Name="Chicago Zoo" Address="23 Zebra Ave" City="Chicago" State="IL">
    <Classification>
      <Animal AnimalName="Lion" />
    </Classification>
    <Classification>
      <Animal AnimalName="Lion" />
    </Classification>
    <Classification>
      <Animal AnimalName="Lion" />
    </Classification>
  </ZooTable>
  <ZooTable Name="Hungry Zoo" Address="45 Lion st" City="Miami" State="FL" Zip="33122">
    <Classification>
      <Animal AnimalName="Lion" />
    </Classification>
    <Classification>
      <Animal AnimalName="Lion" />
    </Classification>
  </ZooTable>
</ZooRoot>

its correct, but added the extra character in end of DTD that is [], i have highlighted in above code.
thats the problem, i dont know how is that []bracket added in dtd.

Do you have the note.dtd file too?

[sekarm]

Its not necessary Dorin. i have given the code

doc.xmlresolver = null;

its does not check with any external resources, that is DTD you mention note.dtd.
you given that above code before document load function, the xmldocument does not care about that note.dtd. Again i tell you need not bother about this. just copy above codes and execute. if you comment the line

doc.xmlresolver=null;

its thrown the error. so i have use that code..
just execute the code, then copy the content in one txt file,then give the name

sample.xml

and give the location. then execute..
Please let me know if you have any concern.

What Validator are you using? What is the exact message you are getting?

[Motoma]

Take a look at http://www.xml.com/lpt/a/1027.
Notice the section titled "Valid XML Output: Including DOCTYPE Declarations". If you have your resolver set to null, C# may be inserting the internal DTD subset in order to maintain the validity of your XML Document.

And the presence of brakets [] will not affect the XML validity.
It's working fine as is.

Thank you all for your kind reply,

I have to check my client validation with that xml file. if that bracket is present the validator gives the error message Invalid file. if i manually remove that bracket then i have check the validation its does not thrown error. so its not a correct process for manually removing the bracket. so that i ask that question. i did not know the validation process in client side.
