is it possible to convert the following XML to the XML shown below using C#. I tried using remove function but it didn't work. I also tried to get the value of root node. Didn't work
<Product_Name>
<hello1>product1</hello1>
<hello2>product2</hello2>
<hello3>product3</hello3>
<hello4>product4</hello4>
</Product_Name>
<product_Price>
<hello1>111</hello1>
<hello2>222</hello2>
<hello3>333</hello3>
<hello4>444</hello4>
</product_Price>
If you just want to fetch the inner xml,you can use the XmlReader's ReadInnerXml.The innerXML is fetched as a string(skipping the root node).
var xmlReader = XElement.Load("data.xml").CreateReader();
xmlReader.MoveToContent();
string innerXml = xmlReader.ReadInnerXml();
If you have access to Linq to XML, you should you XDocument.
caveat: I believe your xml is malformed - you should have something like:
<?xml version="1.0" encoding="utf-8"?>
Add the first xml tag to the xml.
string xml = #"<?xml version="1.0" encoding="utf-8"?>
<Employees>
<Product_Name>
<hello1>product1</hello1>
<hello2>product2</hello2>
<hello3>product3</hello3>
<hello4>product4</hello4>
</Product_Name>
<product_Price>
<hello1>111</hello1>
<hello2>222</hello2>
<hello3>333</hello3>
<hello4>444</hello4>
</product_Price>
</Employees>";
XDocument xDoc = XDocument.Parse(xml);
// get the elements
var rootElements = xDoc.Root.Elements();
Alternatively, you can load the xml from a file:
XDocument xDoc = XDocument.Load("xmlFile.xml");
You can store it as XmlNodeList to be well-formed. Here's a working example of how to do it:
XmlDocument xml= new XmlDocument();
xml.LoadXml(#"<Employees>
<Product_Name>
<hello1>product1</hello1>
<hello2>product2</hello2>
<hello3>product3</hello3>
<hello4>product4</hello4>
</Product_Name>
<product_Price>
<hello1>111</hello1>
<hello2>222</hello2>
<hello3>333</hello3>
<hello4>444</hello4>
</product_Price>
</Employees>");
var nodeList = xml.SelectNodes("Employees");
foreach (XmlNode node in nodeList)
{
Console.WriteLine(node.InnerXml); //this will give you your desired result
}

I'm in a situation where i need to get rid of my parentnode, but not my childnodes.
Here is how it loooks:
<?xml version="1.0" encoding="utf-8"?>
<ns0:MisMessage>
<mislife>
<party/>
<datetime>2018-06-04T09:35:33</datetime>
<insurance">
<number>123</number>
<amount>3</amount>
<indicator></indicator>
<text>asd</text>
</insurance>
</mislife>
<ns0:Message/>
</ns0:MisMessage>
And here is how i want it to look after i'm done.
<mislife>
<party/>
<datetime>2018-06-04T09:35:33</datetime>
<insurance">
<number>123</number>
<amount>3</amount>
<indicator></indicator>
<text>asd</text>
</insurance>
</mislife>
Is there any easy way to do this? I have tried and tried and tried. I have been looking all over the internet and i can't find out how to do it. The thing i want to remove will always be named ns0: in the beggning. Can i do it by removeing with substrings? THANKS!
I solved it like below, i converted the XMLDocument to XDocument and then used the descendants. Just like #bommelding showed in his example. Thank you all!
var xDocument = ToXDocument(xmlDocument);
if (xDocument != null)
{
var mislife = xDocument.Descendants("mislife").FirstOrDefault();
if (mislife != null)
{
return mislife;
}
}
public static XDocument ToXDocument(XmlDocument xmlDocument)
{
using (var nodeReader = new XmlNodeReader(xmlDocument))
{
nodeReader.MoveToContent();
return XDocument.Load(nodeReader);
}
}
XDocument doc = XDocument.Load(fileName);
XElement data = doc
.Descendants("mislife") // find your target
.Single(); // be brave, there should be exactly 1
data.Save(otherFileName); // saves with document <? ... ?>
Simple way with Linq (remember to add using System.Xml.Linq;):
string testxml = #"
<?xml version=""1.0"" encoding=""UTF-8""?>
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>";
XDocument doc = XDocument.Parse(testxml).Descendants().First().Document;
doc will be your xml without the root element
XDocument can load from files with
XDocument.Load("path");
or read XML like I did with
Xml.Parse("<xml....>");
and have also other options.
Result is:
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>

Hi below are the XML files which is master XML
<?xml version="1.0" encoding="utf-16"?>
<Verify>
<ver>
<ECU>
<values>
</values>
</ECU>
</ver>
</Verify>
I have multiple files which are of same structure as below
<?xml version="1.0" encoding="utf-16"?>
<Verify>
<ver>
<ECU>
<values>
</values>
</ECU>
</ver>
</Verify>
I want my output as
<?xml version="1.0" encoding="utf-16"?>
<Verify>
<ver>
<ECU>
<values>
</values>
</ECU>
<ECU>
<values>
</values>
</ECU>
<ECU>
<values>
</values>
</ECU>
</ver>
</Verify>
I am using below code to read first one as master xml
and other files from xmls folder. I want to add ECU node from these files under ECU node of master file.
XmlDocument xmlMaster = new XmlDocument();
xmlMaster.Load(#"C:\MasterXMLFile.xml");
XmlElement masterRoot = xmlMaster.DocumentElement;
XmlNode masterParent = masterRoot.LastChild.LastChild;
var downloadfolder = #"C:\AllXMLs\xmls\";
string[] files = Directory.GetFiles(downloadfolder);
foreach (var xx in files)
{
XmlNode masterNode = masterRoot.LastChild.LastChild;
XmlDocument xdoc = new XmlDocument();
xdoc.Load(xx);
XmlElement root = xdoc.DocumentElement;
XmlElement tempNode = (XmlElement)root.LastChild.LastChild;
masterRoot.InsertAfter(tempNode, masterRoot.SelectSingleNode("//ECU").ParentNode);
}
xmlMaster.Save(#"C:\mergeg.xml");
I am getting error at InsertAfter statement as Object reference not set to an instance of an object.
Please suggest me any solution.
Your tempNode is from xdoc document context. You should import it to xmlMaster document context:
XmlNode importedECU = xmlMaster.ImportNode(tempNode, true);
Also instead of InsertAfter it's better to use AppendChild and append new ECU nodes as children of master ver element:
var masterVer = masterRoot.SelectSingleNode("//ver");
foreach(var file in files)
{
var xdoc = new XmlDocument();
xdoc.Load(file);
var tempNode = xdoc.DocumentElement.LastChild.LastChild;
var importedECU = xmlMaster.ImportNode(tempNode, true);
masterVer.AppendChild(importedECU);
}
Your InsertAfter should be on the parentNode of the node you want to insert after, so the parent of tempNode.
I'm trying to change a the value for the model atribute from the following .xml file.
<MTConnectDevices xmlns="urn:mtconnect.org:MTConnectDevices:1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:mtconnect.org:MTConnectDevices:1.1 http://www.mtconnect.org/schemas/MTConnectDevices_1.1.xsd">
<Header version="1.1" sender="Company MTConnect Instance" creationTime="2010-08-26T19:00:47-07:00" instanceId="2" bufferSize="131072" />
<Devices>
<Device name="XX" iso841Class="1" uuid="000" id="id1001">
<Description manufacturer="name" serialNumber="Serial Number" model="UNDEFINED">
</Description>
This is what I've tried but it's not working as it's not changing the value for model.
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(mypath);
var nsmgr = new XmlNamespaceManager(xmlDoc.NameTable);
nsmgr.AddNamespace("ns", xmlDoc.DocumentElement.NamespaceURI);
var node = xmlDoc.SelectSingleNode("/ns:MTConnectDevices/ns:Header/ns:Devices/ns:Device/ns:Description", nsmgr);
node.Attributes["model"].Value = "changed";
xmlDoc.Save(mypath);
Can anyone give me a hand and tell me how to fix this?
Your xml contains namespaces, so you have to use them while retrieving node.
It can be done something like this:
var nsmgr = new XmlNamespaceManager(xmlDoc.NameTable);
nsmgr.AddNamespace("ns", xmlDoc.DocumentElement.NamespaceURI);
var node = xmlDoc.SelectSingleNode("/ns:MTConnectDevices/ns:Devices/ns:Device/ns:Description", nsmgr);

Hi, I can't parse xml. I want write some node values in file, but as result I get an empty txt file.
You want: artistNode.InnerText
Not: artistNode.value
I tries to parse a XML file (get it from Dependacy Graph in VS 2012).
Here is sample of my .xml file
<?xml version="1.0" encoding="utf-8"?>
<DirectedGraph xmlns="http://schemas.microsoft.com/vs/2009/dgml">
<Nodes>
<Node Id="#101" Category="CodeSchema_ProjectItem" FilePath="$(ProgramFiles)\windows kits\8.0\include\um\unknwnbase.h" Label="unknwnbase.h" />
<Node Id="#103" Category="CodeSchema_ProjectItem" FilePath="$(ProgramFiles)\windows kits\8.0\include\shared\wtypesbase.h" Label="wtypesbase.h" />
in here, I needs to remove attribute "xmlns" from DirectedGraph.
here's my source to remove this
XmlNodeList rootNode = xmlDoc.GetElementsByTagName("DirectedGraph");
foreach (XmlNode node in rootNode)
{
node.Attributes.RemoveNamedItem("xmlns");
}
but this code doesn't work. If I don't delete this I can't select node like
XmlNodeList nodes = xmlDoc.DocumentElement.SelectNodes("/DirectedGraph/Nodes/Node");
What should I do?
If you like you can work with the namespace instead of removing the declaration:
var xml = #"<?xml version=""1.0"" encoding=""utf-8""?>
<DirectedGraph xmlns=""http://schemas.microsoft.com/vs/2009/dgml"">
<Nodes>
<Node Id=""#101"" Category=""CodeSchema_ProjectItem"" FilePath=""$(ProgramFiles)\windows kits\8.0\include\um\unknwnbase.h"" Label=""unknwnbase.h"" />
<Node Id=""#103"" Category=""CodeSchema_ProjectItem"" FilePath=""$(ProgramFiles)\windows kits\8.0\include\shared\wtypesbase.h"" Label=""wtypesbase.h"" />
</Nodes>
</DirectedGraph>";
var doc = new XmlDocument();
doc.LoadXml(xml);
var manager = new XmlNamespaceManager(doc.NameTable);
manager.AddNamespace("d", "http://schemas.microsoft.com/vs/2009/dgml");
var nodes = doc.DocumentElement.SelectNodes("/d:DirectedGraph/d:Nodes/d:Node", manager);
Console.WriteLine(nodes.Count);
Use:
private static XElement RemoveAllNamespaces(XElement xmlDocument)
{
if (!xmlDocument.HasElements)
{
XElement xElement = new XElement(xmlDocument.Name.LocalName);
xElement.Value = xmlDocument.Value;
foreach (XAttribute attribute in xmlDocument.Attributes())
xElement.Add(attribute);
return xElement;
}
return new XElement(xmlDocument.Name.LocalName, xmlDocument.Elements().Select(el => RemoveAllNamespaces(el)));
}
