I have a class array that I'm going to pass to XML to send it later to SQL Server Stored Procedure.
The problem is that when I execute StringWriter it adds some scape caracters (=\) that appears in the final XML.
My code is the following:
public XmlDocument ToXML(object obj_to_xml)
{
string str_XML;
XmlDocument xml = new XmlDocument();
var stringwriter = new System.IO.StringWriter();
var serializer = new XmlSerializer(obj_to_xml.GetType());
serializer.Serialize(stringwriter, obj_to_xml);**
//at this point the format is correct, for example stringwriter contains:
<?xml version="1.0" encoding="utf-16"?>
<ArrayOfRegistroPrestamo xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<RegistroPrestamo>
<Id>1</Id>
<Cedula>8-834-789</Cedula>
<Nombre>Amarillos</Nombre>
<Apellido>Perez</Apellido>
</RegistroPrestamo>
<RegistroPrestamo>
<Id>0</Id>
<Cedula />
<Nombre />
<Apellido />
</RegistroPrestamo>
</ArrayOfRegistroPrestamo>
//the problem comes with this line
xml.LoadXml(stringwriter.ToString());
//final XML looks like this:
<?xml version=\"1.0\" encoding=\"utf-16\"?>
<ArrayOfRegistroPrestamo xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">
<RegistroPrestamo>
<Id>1</Id>
<Cedula>8-834-789</Cedula>
<Nombre>Amarillos</Nombre>
<Apellido>Perez</Apellido>
</RegistroPrestamo>
<RegistroPrestamo>
<Id>0</Id>
<Cedula />
<Nombre />
<Apellido />
</RegistroPrestamo>
</ArrayOfRegistroPrestamo>
return xml;
}
When SQL Server tries to parse the XML Code:
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "P_Save_Procedure";
cmd.Parameters.Add("#Registros", SqlDbType.Xml).Value = xml;
Stored Procedure Text
Create procedure [dbo].[P_Save_Procedure]
(#Registros as xml)
as
begin
select distinct 'Id' = x.v.value('Id[1]', 'Int')
from #Registros.nodes('/ArrayOfRegistroPrestamo/RegistroPrestamo') x(v)
end
I got the error:
Mens. 9413, Level 16, State 1, Line 4
XML parsing: line 1, character 37; It expected a string literal
If I call the SP manually with the correct version of the XML:
<?xml version="1.0" encoding="utf-16"?>
<ArrayOfRegistroPrestamo xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<RegistroPrestamo>
<Id>1</Id>
<Cedula>8-834-789</Cedula>
<Nombre>Amarillos</Nombre>
<Apellido>Perez</Apellido>
</RegistroPrestamo>
<RegistroPrestamo>
<Id>0</Id>
<Cedula />
<Nombre />
<Apellido />
</RegistroPrestamo>
</ArrayOfRegistroPrestamo>
The result is the expected.
Already have spend 2 days tryng to find a way to get the correct sintax for the XML and got nothing.

I cannot deserialize the serialized dataset correctly if it has dates. The result is the dates are considered as a separate table instead of columns itself. It seems that it is not parsed correctly. How do I fix this?
Here are the variables under inspection after the serialization and deserialization. You can see that the deserializedDataSet.Tables has 2 counts where its original is just 1 count. I printed the table names and shows that the second table was date. Moreover, I can access the date column in the original data set but unable to access in the deserialized version.
Here is the serialized data of the dataset.
<?xml version="1.0" standalone="yes"?>
<NewDataSet>

Here is my current code:

{
var memoryStream = new MemoryStream();
dataSet.WriteXml(memoryStream, XmlWriteMode.IgnoreSchema);
dataSet.WriteXml("input.xml");
memoryStream.Flush();
memoryStream.Position = 0;
return memoryStream;
}
public static DataSet Deserialize(MemoryStream stream)
{
var dataSet = new DataSet();
dataSet.ReadXml(stream);
dataSet.WriteXml("output.xml");
return dataSet;
}
}
I'm trying to read the APP_DATE element in this xml message. Tried using LINQ but unable to read MyResult
<?xml version="1.0" encoding="utf-8" ?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<MyResponse xmlns="http://tempuri.org/">
<MyResult>
<APP_TYPE>I</APP_TYPE>
<APP_NO>152240</APP_NO>
<APP_DATE>10/03/2016</APP_DATE>
</MyResult>
</MyResponse>
</soap:Body>
</soap:Envelope>
Can't be sure because you didn't supply any example code but I assume you struggle because of the namespaces. So try this:
XmlDocument doc = new XmlDocument();
doc.Load("data.xml");
XmlNamespaceManager ns = new XmlNamespaceManager(doc.NameTable);
ns.AddNamespace("soap", "http://www.w3.org/2003/05/soap-envelope");
ns.AddNamespace("x", "http://tempuri.org/");
var result = doc.SelectSingleNode("//soap:Envelope/soap:Body/x:MyResponse/x:MyResult/x:APP_DATE", ns).InnerText;
For deeper understanding you can read this question
Using Linq it will be like this:
var result = XDocument.Load("data.xml").Root
.Descendants(XName.Get("APP_DATE", "http://tempuri.org/"))
.FirstOrDefault()?.Value;
See how in both examples I have to specify the namespaces of what I'm looking for
I have an XML file and I wanna extract some elements using XPathSelectElements("..."). It works fine but I have no idea how to save the extracted data into a new XML file with a new outer wrap
Here's what I've got, XPathSelectElements works fine:
var doc = XDocument.Load("XXX.xml");
var nData = doc.XPathSelectElements("Orders/Order[#ID > 1]");
//code to save data to a new file...
My original xml file is like this:
<?xml version="1.0" encoding="utf-8"?>
<Orders>
<Order ID="1">aaa</Order>
<Order ID="2">bbb</Order>
<Order ID="3">ccc</Order>
</Orders>
And I wanna save the result to a new xml file and with an extra wrap like this:
<?xml version="1.0" encoding="utf-8"?>
<newWrap>
<Orders>
<Order ID="2">bbb</Order>
<Order ID="3">ccc</Order>
</Orders>
</newWrap>
Any help? Thanks a lot~
This is one possible way :
var nData = doc.XPathSelectElements("Orders/Order[#ID > 1]");
var root = new XElement("newWrap",
new XElement("Orders", nData)
);
var newDoc = new XDocument(root);
newDoc.Save("new_file.xml");

How do I get the innertext of the OverallResult element using SelectSingleNode?
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<ProcessResp xmlns="http://www.w3.org/2005/Atom">
<Result>
<OverallResult>Success</OverallResult>
var doc = new XmlDocument();
doc.LoadXml(xml);
var text = doc.SelectSingleNode("Example/Node/text()").InnerText; // or .Value
returns
"Some text here\r\n "
and text.Trim() returns
"Some text here"
Please go through the below link for XML related queries its very useful for begginers!

for your answer(i havnt tried it though try by changing like this in ur code)
doc.SelectSingleNode("soap/ProcessResp/ Result/OverallResult/text()").InnerText;
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

How can I extract the portion
<Header>
<Company Code="" />
<CommonCarrierCode />
<InputFileName InputIDPk="">F:\ReconNew\TmesysRec20100111.rec</InputFileName>
<BatchNumber>000152</BatchNumber>
<InputStartDateTime>2010-02-26 11:47:00</InputStartDateTime>
<InputFinishDateTime>2010-02-26 11:47:05</InputFinishDateTime>
<RecordCount>8</RecordCount>
</Header>
from the above xml file.
I need the c# code to extract a part of xml tag from an xml file.
If the file isn't too big (smaller than a few MB), you can load it into an XmlDocument:
XmlDocument doc = new XmlDocument();
doc.Load(#"C:\yourfile.xml");
and then you can parse for the <Header> element using an XPath expression:
XmlNode headerNode = doc.SelectSingleNode("/eRecon/Header");
if(headerNode != null)
{
string headerNodeXml = headerNode.OuterXml;
}
You can use XPath like in this tutorial:
http://www.codeproject.com/KB/cpp/myXPath.aspx
Use Linq-to-xml:
XDocument xmlDoc = XDocument.Load(#"c:\sample.xml");
var header = xmlDoc.Descendants("Header").FirstOrDefault();
Linq version
string fileName=#"d:\xml.xml";
var descendants = from i in XDocument.Load(fileName).Descendants("Header")
select i;
