save separate separate xml file base on orderid

Hi all currently i have saved all the xml file in one file . but i need to save in separate file. could you please help me on it.
current code :-
System.Data.DataTable checkFile = new System.Data.DataTable();
sql = "sql";
DBCon clsDB = new DBCon(SAPCompanySettings.MSSQLConnectionString);
clsDB.Execute(sql, ref checkFile);
var stringwriter = new StringWriter();
using (var xmlWriter = XmlWriter.Create(stringwriter, new XmlWriterSettings { Indent = true }))
{
xmlWriter.WriteStartDocument();
xmlWriter.WriteStartElement("Root");
var groups = checkFile.AsEnumerable().GroupBy(x => new { DocNum = x.Field<int>("orderid"), Type = x.Field<string>("Type"), Status = x.Field<string>("Status"), productno = x.Field<string>("productno"), ProductDescription = x.Field<string>("ProductDescription"), uom = x.Field<string>("uom"), customer = x.Field<string>("customer"), remark = x.Field<string>("remark"), U_JobNumber = x.Field<string>("U_JobNumber"), U_SalesPerson = x.Field<string>("U_SalesPerson"), U_JobType = x.Field<string>("U_JobType"), PlannedQty = x.Field<decimal>("PlannedQty"), OriginNum = x.Field<int?>("OriginNum"), orderdate = x.Field<DateTime>("orderdate"), duedate = x.Field<DateTime>("duedate") });
foreach (var group in groups)
{
xmlWriter.WriteStartElement("productionorder");
xmlWriter.WriteAttributeString("orderid", group.Key.DocNum.ToString());
xmlWriter.WriteElementString("type", group.Key.Type);
xmlWriter.WriteElementString("status", group.Key.Status);
xmlWriter.WriteElementString("productno", group.Key.productno); xmlWriter.WriteElementString("ProductDescription", group.Key.ProductDescription);
xmlWriter.WriteElementString("PlannedQty",group.Key.PlannedQty.ToString());
xmlWriter.WriteElementString("uom", group.Key.uom);
xmlWriter.WriteElementString("salesorder", group.Key.OriginNum.ToString()); xmlWriter.WriteElementString("customer", group.Key.customer);
xmlWriter.WriteElementString("Remarks", group.Key.remark);
xmlWriter.WriteStartElement("date");
xmlWriter.WriteElementString("orderdate", group.Key.orderdate.ToString());
xmlWriter.WriteElementString("duedate", group.Key.duedate.ToString());
xmlWriter.WriteEndElement();
xmlWriter.WriteElementString("jobdescription", group.Key.U_JobNumber);
xmlWriter.WriteElementString("salesperson", group.Key.U_SalesPerson);
xmlWriter.WriteElementString("jobtype", group.Key.U_JobType);
foreach (DataRow row in group)
{
xmlWriter.WriteStartElement("Components");
xmlWriter.WriteElementString("itemno", row.Field<string>("itemno"));
xmlWriter.WriteEndElement();
}
xmlWriter.WriteEndElement();
var sql2 = "update IS_XML_generated='Y' from OWOR where DocNum=group.Key.DocNum";
clsDB.Execute(sql2);
}
xmlWriter.WriteEndElement();
}
var xml = stringwriter.ToString();
XmlDocument docSave = new XmlDocument();
docSave.LoadXml(stringwriter.ToString());
docSave.Save(System.IO.Path.Combine(#"C:\DEMO PSL\DOXMLFILE", "Filename.xml"));
Current output:-
filename.xml:-both order is saved in same file
<?xml version="1.0" encoding="utf-16"?>
<Root>
<productionorder orderid="1">
...................
</productionorder>
<productionorder orderid="2">
...............
</productionorder>
</Root>
but expected output :-i need to save different different file
1.xml :-
<?xml version="1.0" encoding="utf-16"?>
<Root>
<productionorder orderid="1">
..............
</productionorder>
</Root>
2.xml :-
<?xml version="1.0" encoding="utf-16"?>
<Root>
<productionorder orderid="2">
............
</productionorder>
</Root>

I swapped the using and the foreach loops. I also modify filename so each filename is unique.
System.Data.DataTable checkFile = new System.Data.DataTable();
sql = "sql";
DBCon clsDB = new DBCon(SAPCompanySettings.MSSQLConnectionString);
clsDB.Execute(sql, ref checkFile);
var groups = checkFile.AsEnumerable().GroupBy(x => new { DocNum = x.Field<int>("orderid"), Type = x.Field<string>("Type"), Status = x.Field<string>("Status"), productno = x.Field<string>("productno"), ProductDescription = x.Field<string>("ProductDescription"), uom = x.Field<string>("uom"), customer = x.Field<string>("customer"), remark = x.Field<string>("remark"), U_JobNumber = x.Field<string>("U_JobNumber"), U_SalesPerson = x.Field<string>("U_SalesPerson"), U_JobType = x.Field<string>("U_JobType"), PlannedQty = x.Field<decimal>("PlannedQty"), OriginNum = x.Field<int?>("OriginNum"), orderdate = x.Field<DateTime>("orderdate"), duedate = x.Field<DateTime>("duedate") });
int count = 1;
foreach (var group in groups)
{
var stringwriter = new StringWriter();
using (var xmlWriter = XmlWriter.Create(stringwriter, new XmlWriterSettings { Indent = true }))
{
xmlWriter.WriteStartDocument();
xmlWriter.WriteStartElement("Root");
xmlWriter.WriteStartElement("productionorder");
xmlWriter.WriteAttributeString("orderid", group.Key.DocNum.ToString());
xmlWriter.WriteElementString("type", group.Key.Type);
xmlWriter.WriteElementString("status", group.Key.Status);
xmlWriter.WriteElementString("productno", group.Key.productno); xmlWriter.WriteElementString("ProductDescription", group.Key.ProductDescription);
xmlWriter.WriteElementString("PlannedQty",group.Key.PlannedQty.ToString());
xmlWriter.WriteElementString("uom", group.Key.uom);
xmlWriter.WriteElementString("salesorder", group.Key.OriginNum.ToString()); xmlWriter.WriteElementString("customer", group.Key.customer);
xmlWriter.WriteElementString("Remarks", group.Key.remark);
xmlWriter.WriteStartElement("date");
xmlWriter.WriteElementString("orderdate", group.Key.orderdate.ToString());
xmlWriter.WriteElementString("duedate", group.Key.duedate.ToString());
xmlWriter.WriteEndElement();
xmlWriter.WriteElementString("jobdescription", group.Key.U_JobNumber);
xmlWriter.WriteElementString("salesperson", group.Key.U_SalesPerson);
xmlWriter.WriteElementString("jobtype", group.Key.U_JobType);
foreach (DataRow row in group)
{
xmlWriter.WriteStartElement("Components");
xmlWriter.WriteElementString("itemno", row.Field<string>("itemno"));
xmlWriter.WriteEndElement();
}
xmlWriter.WriteEndElement();
var sql2 = "update IS_XML_generated='Y' from OWOR where DocNum=group.Key.DocNum";
clsDB.Execute(sql2);
xmlWriter.WriteEndElement();
}
var xml = stringwriter.ToString();
XmlDocument docSave = new XmlDocument();
docSave.LoadXml(stringwriter.ToString());
docSave.Save(System.IO.Path.Combine(#"C:\DEMO PSL\DOXMLFILE", "Filename" + count.ToString() + ".xml"));
count++;
}

In the body tag, I'd like to group the data first by the scheme-code and inside the code, group the data by the emp-code in that scheme and then by the data(pin, empr-contr,empyee-contr...) having the empr-code. The serial-no(int) for each data tag will be 0,1,2,3....T999 depending on the number of data tags in the parent employer tag. Please see further example below

How can I generate it using XMLDocument or XMLWriter

Try following xml linq. I put your input file into a text file and then read into DataTable. Then create XML from table :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.Data;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
const string INPUT_FILENAME = #"c:\temp\test.txt";
const string OUTPUT_FILENAME = #"c:\temp\test.xml";
static DataTable dt = new DataTable();
static XDocument doc;
static void Main(string[] args)
{
ReadData(INPUT_FILENAME);
dt = dt.AsEnumerable()
.OrderBy(x => x.Field<string>("scheme-code"))
.ThenBy(x => x.Field<string>("emp-code"))
.ThenBy(x => x.Field<string>("pin"))
.CopyToDataTable();
CreateXml();
doc.Save(OUTPUT_FILENAME);
}
static void ReadData(string filename)
{
int rowNumber = 0;
string line = "";
StreamReader reader = new StreamReader(INPUT_FILENAME);
while ((line = reader.ReadLine()) != null)
{
string[] splitData = line.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries).ToArray();
if (++rowNumber == 1)
{
for (int i = 0; i < splitData.Length; i++)
{
if (i < 3)
{
dt.Columns.Add(splitData[i], typeof(string));
}
else
{
dt.Columns.Add(splitData[i], typeof(decimal));
}
}
}
else
{
DataRow newRow = dt.Rows.Add();
for (int i = 0; i < splitData.Length; i++)
{
if (i < 3)
{
newRow[i] = splitData[i];
}
else
{
newRow[i] = decimal.Parse(splitData[i]);
}
}
}
}
reader.Close();
}
static void CreateXml()
{
string xmlns_rmas = "value here";

_return.Add(body);
foreach(var schemeGroup in dt.AsEnumerable().GroupBy(x => x.Field<string>("scheme-code")))
{
XElement scheme = new XElement("scheme");
body.Add(scheme);
XElement code = new XElement("code", schemeGroup.Key);
scheme.Add(code);
foreach(var empCodeGroup in schemeGroup.GroupBy(y => y.Field<string>("emp-code")))
{

scheme.Add(employer);
int serialNumber = 0;

Load Data to the DataSet and use Write XML. This is the simplest way you can try
DataSet oDsData = new DataSet();
oDsData.WriteXml("path", XmlWriteMode.WriteSchema);

This could be one of the solution if your data is in MSSQL server. I assumed your data resides in a table (##tmp_test) in database.
public string GetXML()
{
XmlDocument document = new XmlDocument();
XmlDeclaration xmlDeclaration = document.CreateXmlDeclaration("1.0", "UTF-8", null);
XmlElement root = document.DocumentElement;
document.InsertBefore(xmlDeclaration, root);
var returnElement = document.CreateElement( "return");
returnElement.SetAttribute("xmlns:rmas", "value here");
returnElement.SetAttribute("xmlns:xsi", "value here");
returnElement.SetAttribute("noNamespaceSchemaLocation", "value here");
var header = document.CreateElement("header");
var rc = document.CreateElement("return-code");
rc.InnerText = "\"\"";
header.AppendChild(rc);
var rd = document.CreateElement("return-desc");
rd.InnerText = "\"\"";
header.AppendChild(rd);
var aad = document.CreateElement("as-at-date");
aad.InnerText = "\"\"";
header.AppendChild(aad);
var oc = document.CreateElement("operator-code");
oc.InnerText = "\"\"";
header.AppendChild(oc);
returnElement.AppendChild(header);
var body = document.CreateElement("body");
body.InnerXml = GetBodyXML();
returnElement.AppendChild(body);
document.AppendChild(returnElement);
return document.OuterXml;
}
private string GetBodyXML()
{
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
using (SqlCommand command = new SqlCommand())
{
command.Connection = connection;
command.CommandText = #"

Attempting to get single value from XDocument, nothing appears to work

I am just trying to get the value from MessageInfo.. Sender here is an excerpt of the xml. I just want the "Senders" value. I have tried many different things with XDocument, and wanted to use a Linq Query
I have tried,
var query1 = doc.Descendants("MessageInfo").Select(s => new MessageInfo
{
SYSGENID = s.Element("SysGenID").Value,
TIME_STAMP = s.Element("TimeStamp").Value,
SENDER = s.Element("Sender").Value,
RECEIVER = s.Element("Receiver").Value,
ENTITY_CODE = s.Element("EntityCode").Value
}).FirstOrDefault();
the query1 returns null. Following is example of xml
I also have tried
XDocument doc = XDocument.Load(filePath);
var messageInfo = doc.Root.Elements("MessageInfo");
var res = from m in messageInfo
select new
{
msgInfo = m.Element("MessageInfo").Value
};
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"

You have a namespace that you have to use.
XNamespace ns = "http://www.nwpp.org/eide";
var query1 = doc.Descendants(ns +"MessageInfo").Select(s => new MessageInfo
{
SYSGENID = s.Element(ns +"SysGenID").Value,
TIME_STAMP = s.Element(ns +"TimeStamp").Value,
SENDER = s.Element(ns +"Sender").Value,
RECEIVER = s.Element(ns +"Receiver").Value,
ENTITY_CODE = s.Element(ns +"EntityCode").Value
}).FirstOrDefault();

XML to local database in windows phone 7

This function (look CODE) occur when xml file is downloaded from my server.. Now I want to load it in my local database...
XML

etc...
CODE:
void downloader_Completed(object sender, DownloadStringCompletedEventArgs e)
{
if (e.Error != null)
return;
XElement quest = XElement.Parse(e.Result);
using (QuestionContext context = new QuestionContext(ConnectionString))
{
for (int i = 0; i < quest.Length; i++)
{
Question q = new Question();
q.idQuestion = ;
q.Question = ;
q.CorrectAns = ;
q.WrongAns1 = ;
q.WrongAns2 = ;
q.WrongAns3 = ;
context.QuestionsDB.InsertOnSubmit(q);
context.SubmitChanges();
}
}
}
I have 2 questions:
1)How to read the xml content and write them in:
q.idQuestion = ;
q.Question = ;
q.CorrectAns = ;
q.WrongAns1 = ;
q.WrongAns2 = ;
q.WrongAns3 = ;
2)for (int i = 0; i < quest.Length; i++) Herequest.Length give error (I know why)... How to make custom function to get the length? I need it to count <Questions> tags

Your xaml is not in valid format, because it has multiple root elements (Questions).
Assuming if it is in the correct format like this (I have modifiec)
string xmlData = #"<?xml version=""1.0"" encoding=""utf-8"" ?>
<Questions>
<Question>
<idQuestion>1</idQuestion>
<QuestionName>Question 1</QuestionName>
<CorrectAns>Ans1</CorrectAns>
<WrongAns1>Ans2</WrongAns1>
<WrongAns2>Ans3</WrongAns2>
<WrongAns3>Ans4</WrongAns3>
<Category>CategoryName</Category>
</Question>
<Question>
<idQuestion>2</idQuestion>
<QuestionName>Question 2</QuestionName>
<CorrectAns>Ans1</CorrectAns>
<WrongAns1>Ans2</WrongAns1>
<WrongAns2>Ans3</WrongAns2>
<WrongAns3>Ans4</WrongAns3>
<Category>CategoryName</Category>
</Question>
</Questions>";
You can have any number of tags as above
Now, you can convert this data into classes as shown below
XElement quest = XElement.Parse(xmlData);
var questionsData = from qn in quest.Descendants("Question")
select new Question
{
idQuestion = int.Parse(qn.Element("idQuestion").Value),
QuestionName = qn.Element("QuestionName").Value,
CorrectAns = qn.Element("CorrectAns").Value,
WrongAns1 = qn.Element("WrongAns1").Value,
WrongAns2 = qn.Element("WrongAns2").Value,
WrongAns3 = qn.Element("WrongAns3").Value
};
var Questions = questionsData.ToList();
var noofquestions = Questions.Count;
//If you want any question with specific id, say '2'
int idQuestion = 2;
var question = Questions.Where(item => item.idQuestion == idQuestion).First();
Here my Question class is like this
class Question
{
public int idQuestion ;
public string QuestionName ;
public string CorrectAns ;
public string WrongAns1 ;
public string WrongAns2 ;
public string WrongAns3 ;
}
Now apply the above process to your data, in whatever way applies

Help with Linq to XML

Iv got two DB tables. One containing types(Id, Name) and the other holds datapoints (RefId, Date, Value) that are referenced by the types. I need to create a XML file with the following strukture:
<?xml version='1.0' encoding='utf-8' ?>
<root>
<type>
<name></name>
<data>
<date></date>

</data>
<data>
<date></date>

This is not a working code. Im having problems with LINQ and the inner joins. Could someone please help me to get the correct strukture. I hope its kinda clear what im trying to achive.
Best Regards

var result =
new XDocument(new XElement("root",
from dt in dataTypes
join dp in dataPoints on dt.Id equals dp.RefId
select new XElement("type",
new XElement("name", dt.Name),
new XElement("data",
new XElement("date", dp.PointDate),
new XElement("temp", dp.PointValue)))));
var result =
new XDocument(new XElement("root",
from dt in dataTypes
select new XElement("type",
new XElement("name", dt.Name),
from dp in dataPoints
where dp.RefId == dt.Id
select new XElement("data",
new XElement("date", dp.PointDate),
new XElement("temp", dp.PointValue)))));
