ASP.Net : Xml Version Format

[Vijay Jadhav India]

Hi Experts, My Xml format is :

<Sis>
<Student>
<StudentID>1</StudentID>
<AcademicDetails>2008-2009</AcademicDetails>
<PersonalDetails>
<FirstName>Vijay</FirstName>
<MiddleName>Laxmanrao</MiddleName>
<LastName>Jadhav</LastName>
</PersonalDetails>
</Student>
</Sis>

I have seen lot of Xml's with Version information ie <? xml version="1.0" ?>. My question is that what is a cause that my Xml didn't show version and other information. My Sample code behind for creating Xml is :

    #region Create Student Xml String
    /\* ---------------------------------------------------------- Create Student Xml File --------------------------------------------------------------------- \*/

    private string sCreateStudentXml()
    {
        try
        {
            Consumer.Sis studentDS = new Consumer.Sis();
            Sis.StudentRow student\_row = studentDS.Student.NewStudentRow();

            student\_row.StudentID = 1;
            student\_row.AcademicDetails = "2008-2009";

            studentDS.Student.AddStudentRow(student\_row);

            Sis.PersonalDetailsRow sub\_StudentPersonalDetails\_row = studentDS.PersonalDetails.NewPersonalDetailsRow();

            sub\_StudentPersonalDetails\_row.FirstName = "Vijay";
            sub\_StudentPersonalDetails\_row.MiddleName = "Laxmanrao";
            sub\_StudentPersonalDetails\_row.LastName = "Jadhav";
            sub\_StudentPersonalDetails\_row.StudentRow = student\_row;
            studentDS.PersonalDetails.AddPersonalDetailsRow(sub\_StudentPersonalDetails\_row);

            // Accept the changes
            studentDS.AcceptChanges();

            System.IO.StringWriter writer = new System.IO.StringWriter();

            studentDS.WriteXml(writer, System.Data.XmlWriteMode.WriteSchema);
            return writer.ToString();
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

    #endregion

And my Xsd is :

<?xml version="1.0" encoding="utf-8" ?>
<!--Created with Liquid XML Studio - 30 Day Trial Edition (http://www.liquid-technologies.com)-->
<xsd:schema id="Sis" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:complexType name="StudentPersonalDetails">
xsd:sequence

Why don't you just use it as it is ? Is it causing you problems ?!

Hi Samer, Thanks for reply. Because the XML declaration like : xmlns:xs="http://www.w3.org/2001/XMLSchema". I am going to use later. The purpose is to identify, Xml based on Xsd. Any solution ? :^)

You can use XmlWriter with XmlWriterSettings:

XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = false;
settings.Indent = true;

XmlWriter xmlWriter = xmlWriter = XmlWriter.Create(
@"c:\temp\temp.xml", settings);

studentDS.WriteXml(xmlWriter);
xmlWriter.Close();

Hi all, We have done it. Please view the following code snippet : #region Create Student Xml String /* Create Student Xml File */ private string sCreateStudentXml() { try { Consumer.Sis studentDS = new Consumer.Sis(); Sis.StudentRow student_row = studentDS.Student.NewStudentRow(); student_row.StudentID = 1; student_row.AcademicDetails = "2008-2009"; studentDS.Student.AddStudentRow(student_row); Sis.PersonalDetailsRow sub_StudentPersonalDetails_row = studentDS.PersonalDetails.NewPersonalDetailsRow(); sub_StudentPersonalDetails_row.FirstName = "Vijay"; sub_StudentPersonalDetails_row.MiddleName = "Laxmanrao"; sub_StudentPersonalDetails_row.LastName = "Jadhav"; sub_StudentPersonalDetails_row.StudentRow = student_row; studentDS.PersonalDetails.AddPersonalDetailsRow(sub_StudentPersonalDetails_row); // Accept the changes studentDS.AcceptChanges(); System.IO.StringWriter writer = new System.IO.StringWriter(); studentDS.WriteXml(writer, System.Data.XmlWriteMode.IgnoreSchema); XmlDocument doc = new XmlDocument(); doc.LoadXml(writer.ToString()); XmlNode root = doc.DocumentElement; XmlAttribute att = doc.CreateAttribute("xsi", "noNamespaceSchemaLocation", "http://www.w3.org/2001/XMLSchema-instance"); att.Value = "Sis.xsd"; root.Attributes.Append(att); writer = new System.IO.StringWriter(); doc.Save(writer); string sXML = writer.ToString(); sXML = sXML.Replace("utf-16", "utf-8"); return sXML.ToString(); } catch (Exception ex) { throw ex; } } #endregion Thanks all for being with me! :)
