I'm using this:
public void WriteSettings(string key, string value)
{
XmlWriterSettings xmlSettings = new XmlWriterSettings();
xmlSettings.Indent = true;
xmlSettings.NewLineOnAttributes = true;
XmlWriter writer = XmlWriter.Create(TMP_FULLPATH, xmlSettings);
writer.WriteStartElement("settings");
writer.WriteAttributeString(key, value);
writer.WriteEndAttribute();
writer.WriteEndDocument();
writer.Flush();
writer.Close();
}
But any modification replaces all attributes with only the last remaining attribute that I am trying to add. For example:
current XML:
<?xml version="1.0" encoding="utf-8"?>
<settings TitleFormat="name:%name% date:%date%" />
when I do:
WriteSettings("foo", "baa");
the XML is:
<?xml version="1.0" encoding="utf-8"?>
<settings foo="baa" />
instead of:
<?xml version="1.0" encoding="utf-8"?>
<settings TitleFormat="name:%name% date:%date%" foo="baa" />
How can I fix that?
You are writing a new file, with no consideration at all of the old. To update a document, you must load it into a DOM, edit the DOM, and save the DOM:
var doc = new XmlDocument();
doc.Load(path);
doc.DocumentElement.SetAttribute(key, value);
doc.Save(path);
you are creating new file each time you call XmlWriter.Create(), do something like this.

I build an XML Document which needs to be validated against a xsd file. Thus I need a reference to the xsd file in the root element of the xml. So far I use this C# Code:
var ser = new XmlSerializer(typeof(myspecialtype));
XmlSerializerNamespaces MainNamespace = new XmlSerializerNamespaces();
MainNamespace.Add("xlink", "http://www.w3.org/1999/xlink");
MainNamespace.Add("xsi", "http://www.w3.org/2001/XMLSchema-instance");
using (XmlWriter w = XmlWriter.Create(#"C:\myxmlfile.xml"))
{
w.WriteProcessingInstruction("xml-stylesheet", "type=\"text/xsl\" href=\"utils/somexsl.xsl\"");
ser.Serialize(w, LeBigObject, HauptNs);
}
The resulting Xml begins like this:
<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/xsl" href="utils/somexsl.xsl"?>
<caddy-xml xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xlink="http://www.w3.org/1999/xlink" xmlVersion="03.07.00">
but I need this:
<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/xsl" href="utils/somexsl.xsl"?>
<caddy-xml xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xlink="http://www.w3.org/1999/xlink" xmlVersion="03.07.00" xsi:noNamespaceSchemaLocation="utils/theveryimportant.xsd">
I came across "CreateAttribute" here: Add Namespace to an xml root node c# but I can't put it together with the Serializer. Thank you!
I was pointed to the solution here:
https://social.msdn.microsoft.com/Forums/en-US/e43585c6-181b-4449-8806-b07f82681a2a/how-to-include-xsinonamespaceschemalocation-in-the-xml?forum=asmxandxml
I added this to my class:
[XmlAttribute("noNamespaceSchemaLocation", Namespace = XmlSchema.InstanceNamespace)]
public string attr = "utils/theveryimportant.xsd";
and it works.
I have an XML file with some data on it..for example
<?xml version="1.0" encoding="utf-8"?>
<CreateAndSendMessageRequest xmlns:xsi="http://www.w3.org/2001/XMLSchema-
instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://schemas.communisis.com/lv">
<CompositionRequest>
<Metadata xmlns="http://lv.com/gi/si/common/CommonTypes">
<PolicyReference>250028766505DN</PolicyReference>
<AccountReference>Test1234</AccountReference>
<QuoteReference>Test3214</QuoteReference>
<OutboundTransactionID>string</OutboundTransactionID>
</Metadata>
Now i want to replace POLICY REFERENCE value with some dummy data. I am able to do that but now i have to save it as a new file with a different file name..
How can i achieve that..
For reference i am giving my code.
XmlDocument doc = new XmlDocument();
doc.Load(filepath);
XmlNodeList node = doc.GetElementsByTagName("PolicyReference");
var item =node.Item(0);
string value = item.FirstChild.Value;
string nevalue = value.Replace(value, "Test123");
doc.DocumentElement.;
doc.Save(#"C:\Test\file.xml");
The xml wasn't valid.
Anyway, this is how to make it work:
Xml file:
<?xml version="1.0" encoding="UTF-8"?>
<CreateAndSendMessageRequest>
<CompositionRequest>
<Metadata xmlns="http://lv.com/gi/si/common/CommonTypes">
<PolicyReference>250028766505DN</PolicyReference>
<AccountReference>Test1234</AccountReference>
<QuoteReference>Test3214</QuoteReference>
<OutboundTransactionID>string</OutboundTransactionID>
</Metadata>
</CompositionRequest>
</CreateAndSendMessageRequest>
Code:
XmlDocument doc = new XmlDocument();
doc.Load("bho.xml");
XmlNodeList node = doc.GetElementsByTagName("PolicyReference");
node[0].InnerText = "Test123";
doc.Save("file.xml");
Result xml:
<?xml version="1.0" encoding="UTF-8"?>
<CreateAndSendMessageRequest>
<CompositionRequest>
<Metadata xmlns="http://lv.com/gi/si/common/CommonTypes">
<PolicyReference>Test123</PolicyReference>
<AccountReference>Test1234</AccountReference>
<QuoteReference>Test3214</QuoteReference>
<OutboundTransactionID>string</OutboundTransactionID>
</Metadata>
</CompositionRequest>
</CreateAndSendMessageRequest>
Hope it helps you ^^
I am trying to use xmlwriter to customize my xml file. I have tried using a class to serialize to xml but it does not seem to work. My goal is to have multiple namespace definitions within the "AddO" element, with each element under the messages having a prefix.
Click event:
XmlWriterSettings objSetting = new XmlWriterSettings();
objSetting.Indent = true;
objSetting.NewLineOnAttributes = true;
System.Text.StringBuilder sb = new System.Text.StringBuilder();
using (XmlWriter objWriter = XmlWriter.Create(sb, objSetting))
{
//Request
objWriter.WriteStartDocument();
objWriter.WriteStartElement("Request");
objWriter.WriteStartElement("SName");
objWriter.WriteValue("AocD");
objWriter.WriteEndElement();
objWriter.WriteStartElement("Message");
//objWriter.WriteStartElement("pd", "AddO", "www.google.com");
objWriter.WriteStartElement("pd", "AddO", "www.google.com");
objWriter.WriteStartElement("aoc","CaseD");
objWriter.WriteStartElement("CaseA");
objWriter.WriteStartElement("DocE");
objWriter.WriteEndElement();
objWriter.WriteEndElement();
objWriter.WriteEndElement();
objWriter.WriteEndElement();//CaseD End
objWriter.WriteEndElement();//Message End
objWriter.WriteEndElement();//Request End
objWriter.WriteEndDocument();
File.WriteAllText(Server.MapPath("~/images/test.xml"), sb.ToString());
I get this XML Result:
<?xml version="1.0" encoding="utf-16"?>
<Request>
<SName>AocD</SName>
<Message>
<iepd:AddO xmlns:iepd="www.google.com">
<aoc xmlns="CaseD">
<CaseA>
<DocE>
</DocE>
</CaseA>
</aoc>
</iepd:AddO>
</Message>
</Request>
Trying to get:
<?xml version="1.0" encoding="utf-16"?>
<Request>
<SName>AocD</SName>
<Message>
<iepd:AddO xmlns:iepd="www.google.com" xmlns:a="www.goo.com" xmlns:b="www.gle.com" xmlns:d="www.le.com">
<a:CaseD">
<b:CaseA>
<d:DocE>
</d:DocE>
</b:CaseA>
</a:CaseD>
</iepd:AddO>
</Message>
</Request>
The code below works in C#, no error, no exception. The problem is that the numconfig.xml file won't change after running the code.
C# code:
XmlNodeList xm = new XmlManager(System.Web.HttpContext.Current.Server.MapPath("~/Xml/numconfig.xml")).ReadAllChild(#"//number");
xm[0].SelectSingleNode("abc[#name='upper']").Attributes["value"].Value = "201";
Xml file:
<?xml version="1.0" encoding="utf-8" ?>
<number>
<aaa>
<abc value="200" text="xxxx" name="upper"/>
</aaa>
</number>
How are you trying to commit the changes back to the file? Your code does not show an example eg
using (var streamWriter = new StreamWriter(location))
{
foreach (XmlNode xmlNode in xm)
{
streamWriter.WriteLine(xmlNode.OuterXml);
}
}
I have a xml file, that looks something like this:
<?xml version="1.0" encoding="utf-8"?>
<Settings>
<WhereDoCopy Path="C:\Users\USER\Desktop\jobs" />
</Settings>
What can I do, to add an Element to that file?
XDocument doc = XDocument.Load("your.xml");
XElement item = new XElement(WhereDoCopy ,
new XAttribute("Path", "C:\Users\USER\Desktop\jobs2"));
doc.Root.Add(item);
