This is the XML file
?xml version="1.0" encoding="utf-8"?>
<!--This file is generated by the program.-->
<DATABASE>
<SCENE SCENE_NAME="SCENE_TestSene"></SCENE>
</SCENE>
</DATABASE>
I want to write inside the Element "SCENE SCENE_NAME="SCENE_TestSene""
This is the code where i am writing to the element.
XDocument doc = XDocument.Load("Database.xml");
XElement root = new XElement("XYZ");
root.Add(new XElement("tName", "VIRAT"));
doc.Element("//DATABASE/SCENE[#SCENE_NAME='SCENE_TestSene']").Add(root); // this line crashes the application
doc.Save("Database.xml");
How can i insert the data inside the element.
This is how it should look like after writing.
<DATABASE>
<SCENE SCENE_NAME="SCENE_TestSene">
<XYZ>
<tName>virat</tName>
</XYZ>
</SCENE>
</DATABASE>
Use doc.XPathSelectElement("/DATABASE/SCENE[#SCENE_NAME='SCENE_TestSene']").Add(new XElement("XYZ"),new XElement("tName", "VIRAT"))).

I am trying to append a string to xml document.
I wanna create RDLC in c# and build the xml.
I need to cast or convert a string generated dynamically in the code c# and import it into the "TablixBody" tag.
Here's the code:
<!-- Generating the XmlDocument in c# -->
<?xml version="1.0" encoding="UTF-8"?>
<Report xmlns="http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition" xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">
<Body>
<ReportItems>
<Tablix Name="SOPaymentDetails">
<TablixBody>
<TablixColumns>
<TablixColumn>
<Width>10.83106in</Width>
</TablixColumn>
</TablixColumns>
</TablixBody>
</Tablix>
</ReportItems>
</Body>
</Report>
Maybe something like will be of some help :
XDocument doc = XDocument.Load("rootdoc.xml");
rootdoc.xml may have your intial code.
Then you do this :
XElement tagbody= doc.Elements("TablixBody")[0]:
tagbody.Add(content);
I've got to create a file with xml header and after that i have to put normal data, smthing like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Header>
<Algorithm>alg</Algorithm>
<nod2>aaa</nod2>
<nod3>bbb</nod3>
<node>
<User>
<Email />
<SessionKey />
</User>
</node>
</Header>
Data of the file....
I've already got the code to write it to the file.
Code for that part:
private void setHeader(FileStream output, string nod2, string nod3, string )
{
XmlDocument doc = new XmlDocument();
XmlNode docNode = doc.CreateXmlDeclaration("1.0", "UTF-8", "yes");
doc.AppendChild(docNode);
XmlNode header = doc.CreateElement("Header");
doc.AppendChild(header);
XmlNode algorithm = doc.CreateElement("Algorithm");
algorithm.InnerText = "alg";
header.AppendChild(algorithm);
XmlNode node2= doc.CreateElement("nod2");
node2.InnerText = nod2;
header.AppendChild(node2);
XmlNode node3= doc.CreateElement("nod3");
node3.InnerText = nod3;
header.AppendChild(node3);
XmlNode node= doc.CreateElement("node");
header.AppendChild(node);
XmlNode user1 = doc.CreateElement("User");
node.AppendChild(user1);
XmlNode mail = doc.CreateElement("Email");
user1.AppendChild(mail);
XmlNode sessionKey = doc.CreateElement("SessionKey");
user1.AppendChild(sessionKey);
doc.Save(output);
}
It work's pretty well, but when i want to read it with
private void readHeader(FileStream input, out string algorithm)
{
XmlDocument doc = new XmlDocument();
doc.Load(input);
}
I got an error that when the "Data of the file..." starts: "Data on the root level is invalid".
Is there a way to do it with the data after whole xml, or have i to add the data as a node?
This can be done in multiple ways. In comments, you've indicated that the best way is unacceptable for reasons outside the scope of the discussion. For completeness, I'm going to put that one first anyway. Skip down to tl;dr for what I think you'll have to end up doing.
The preferred way to do this is to base64 encode the encrypted data and put it in a CDATA block:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<File>
<Header>
<Algorithm>alg</Algorithm>
<nod2>aaa</nod2>
<nod3>bbb</nod3>
<node>
<User>
<Email />
<SessionKey />
</User>
</node>
</Header>

That's the canonical answer to this question.
But you've told me that in your case, a requirement has been imposed that you can't do it that way.
Second choice is MIME (actually, MIME might be the first choice and the above might be the second). But I have a feeling they won't like MIME either.
Third choice, read the file as a string and search for some marker that's inserted between the XML and the binary data, something like a MIME boundary.
tl;dr
If they won't let you add such a marker to the file (and I bet they won't), search for the first occurrence of the substring "</Header>":
var xml = File.ReadAllText(filePath);
var endTag = "</Header>";
var headerXML = xml.Substring(0, xml.IndexOf(endTag) + endTag.Length);
var xdHeader = new XmlDocument();
xdHeader.LoadXml(headerXML);
I tested your code with writing directly to a file, doc.Save(#"c:\temp\test1.xml");
And loading from that file works fine. So there is nothing wrong with your xml document. Check your FileStream. Do you flush and close it properly? Does it have UTF-8 encoding?
What's the input in the node strings. Nothing that is invalid according to xml rules?
After a single root node, only comments and processor instructions can be written to xml. So, you can try to write your data in the comments.
It will look like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Header>
...
</Header>
<!-- your data -->
<!-- another data -->
This method has limitations: your data may not contain -- (double-hyphen) and may not end in -.
But it is better, of course, not to do so.
I am trying to access the second element in this xml (google kml type) of file and the issue I am having is I get returned null values for my code unless I remove out the <kml xmlns="http://earth.google.com/kml/2.0"> and the related close from the source file. Here is the code I'm using. (mind you this works if I remove the specified line so what I'm looking for is a clean way to process this file without editing the supplied source file.)
XmlDocument doc = new XmlDocument();
doc.Load("2014_q2.xml");
XmlNodeList xnlNodes = doc.SelectNodes("/kml/Document/Folder");
var Node2Use = xnlNodes.Item(1);
here is the top of the source file:
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.0">
<Document>
<open>1</open>
<Folder>
<name>Pts_2014_q3_point Drawing</name>
<Placemark>
<description>HOLTSVILLE</description>
<name>00501</name>
<Style>
<IconStyle>
<color>ffc0c0c0</color>
I have a break on the var Node2Use = xnlNodes.Item(1); line so I can see the contents and thats where I see that I have a zero value where I should have 2 for Folder (like mentioned I get the 2 when I remove out that kml tagged line.)
You need to include the namespace. Something like this:
XmlDocument doc = new XmlDocument();
doc.Load("2014_q2.xml");
XNamespace ns = "http://earth.google.com/kml/2.0";
XmlNodeList xnlNodes = doc.SelectNodes(ns + "/kml/Document/Folder");
I have following two xml strings
<?xml version="1.0"?>
<AccessRequest xml:lang='en-US'>
<AccessLicenseNumber>YOURACCESSLICENSENUMBER</AccessLicenseNumber>
<UserId>YOURUSERID</UserId>
<Password>YOURPASSWORD</Password>
</AccessRequest>
and
<?xml version="1.0" ?>

I want to append second xml string to first one. I tried writing both XmlDocuments to a XmlWriter. But it throws exception "Cannot write XML declaration. XML declaration can be only at the beginning of the document."
Stream stm = req.GetRequestStream();
XmlDocument doc1 = new XmlDocument();
XmlDocument doc2 = new XmlDocument();
doc1.LoadXml(xmlData1);
doc2.LoadXml(xmlData2);
XmlWriterSettings xws = new XmlWriterSettings();
xws.ConformanceLevel = ConformanceLevel.Fragment;
using (XmlWriter xw = XmlWriter.Create(stm, xws))
{
doc1.WriteTo(xw);
doc2.WriteTo(xw);
}
How can I append it as is? Please help
Remove <?xml version="1.0" ?> from second xml string before appending it to first xml string.
I had this problem in the past. The two lines of code below did the job:
var MyDoc = XDocument.Load("File1.xml");
MyDoc.Root.Add(XDocument.Load("File2.xml").Root.Elements());
If you already have strings ready, then please use the Parse function instead of Load.
Please notice I am using the System.Xml.Linq that uses XDocument instead of XmlDocument class.
EDIT
As I understood, you need both documents to be concatenated as is. The problem is that it will eventually leads to an invalid XML document for two reasons :
the document will contain two root nodes: AccessRequest and RatingServiceSelectionRequest. A valid XML document contains only one root node.
There must be only one <?xml version="1.0" ?> XML declaration at the beginning of a document.
If the UPS api your are using is fed with an invalid XML, you unfortunately can not use XML objects. Therefore you will have to use a simple string concatenation to achieve what you want:
var xml = xmlData1 + xmlData2;
I have some xml data contained in three files (Database.xml, Participants.xml, and ConditionTokens.xml). I am trying to use external entities to place the participants and condition tokens into the database file, but when I run this code...
string xmlPath = Environment.CurrentDirectory + #"\Data\Database.xml";
XElement database = XElement.Load(xmlPath);
...there are no participants or condition tokens in my xml (the HasElements property for "database" is false). There should be two child elements. I get no errors/warnings within Visual Studio (2008), and the live schema validation seems to be happy, but something is not quite right when I run my code.
Could anyone tell me what I'm doing wrong?
I have pasted the three xml files below.
Thanks very much!
-Dan
Database.xml
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE database [
<!ENTITY conditionTokens SYSTEM "ConditionTokens.xml">
<!ENTITY participants SYSTEM "Participants.xml">]>
<database
xmlns="experimentManager"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="experimentManager Database.xsd">
&conditionTokens;
&participants;
</database>
ConditionTokens.xml
<?xml version="1.0" encoding="utf-8" ?>
<conditionTokens>
<conditionToken>
<id>1</id>
<token>LargeToSmall</token>
</conditionToken>
<conditionToken>
<id>2</id>
<token>SmallToLarge</token>
</conditionToken>
</conditionTokens>
Participants.xml
<?xml version="1.0" encoding="utf-8" ?>
<participants>
<participant>
<id>1</id>
<conditionTokenId>1</conditionTokenId>
</participant>
<participant>
<id>2</id>
<conditionTokenId>2</conditionTokenId>
</participant>
</participants>
I would have used the XmlDocument class to load the 3 documents
XmlDocument xmlDatabase = new XmlDocument();
xmlDatabase.Load(databasePath);
XmlDocument xmlTokens = new XmlDocument();
xmlTokens.Load(tokensPath);
XmlDocument xmlParticipants = new XmlDocument();
xmlParticipants.Load(participantsPath);
Then using the ImportNode and AppendNode attach then to each other...
xmlDatabase.FirstChild.AppendNode(xmlDatabase.ImportNode(xmlTokens.FirstChild), true);
xmlDatabase.FirstChild.AppendNode(xmlDatabase.ImportNode(xmlParticipants.FirstChild), true);
That should pretty much do it (or instead of using FirstChild use an xpath selector?)
I ended up using <xs:redefine> instead.
