Remove specefic tag from xml - c#

I have a webservice and it's response is:
<?xml version="1.0" encoding="utf-8" ?>
<string xmlns="http://tempuri.org/">
<contractor-management>
<request-attributes> <corp-id>abcd</corp-id></request-attributes>
</contractor-management>
</string>
I am getting the above response but I want to remove the string tag line. So it should be like this:
<?xml version="1.0" encoding="utf-8" ?>
<contractor-management>
<request-attributes> <corp-id>abcd</corp-id></request-attributes>
</contractor-management>
Due to some reason("-" cannot be used as a part of variable name), I am creating the above like this:
string x;
x = "<contractor-management>";
x += "<request-attributes> ";
x += "<corp-id>abcd</corp-id> ";
x += "</request-attributes> ";
x = "</contractor-management>";


Do like below code, where xmlContent is your current xml contents
XmlDocument xmldoc = new XmlDocument();
xmldoc.LoadXml(xmlContent);
XmlNode firstChild=xmldoc.GetElementsByTagName("string")[0];
XmlNode secondChild = firstChild.FirstChild;
xmldoc.ReplaceChild(secondChild, firstChild);
You can also save this modified xml to a file
xmldoc.Save(#"modified.xml");

How to set namespace on XDocument

I need to acсess xml file. But xml have base namespace whith prefix m:
This is my code, but it do not working, write NullRefference exeptions:
var fileКс = XDocument.Load(somePath);
var allDescrioptions = fileКс.Root.Element("formulas").Elements("formula").ToList();
This is part of xml file:
<?xml version="1.0" encoding="utf-8" ?>
<m:math xmlns:m="http://www.kontur-extern.ru/ФНС 4.0/math.xsd">
<m:formulas>
<m:formula target="#ПрибУб" match="/Файл/Документ/Прибыль/РасчНал" source="Лист 02/стр.060">
</m:formula>
</m:formulas>
</m:math>
I think need to specify namespace, but I don't know how

You can use XNamespace as follow :
XNamespace m = "http://www.kontur-extern.ru/ФНС 4.0/math.xsd";
var fileКс = XDocument.Load(somePath);
var allDescrioptions = fileКс.Root.Element(m+"formulas").Elements(m+"formula").ToList();

Xml parser doesn't work

<?xml version="1.0" encoding="utf-8"?>
<response list="true">
<audio>
<aid>253663595</aid>
<artist>Example</artist>
<duration>389</duration>
<lyrics_id>57485771</lyrics_id>
<genre>18</genre>
</audio>
<audio>
<aid>253663595</aid>
<artist>Example1</artist>
<duration>400</duration>
<lyrics_id>57485772</lyrics_id>
<genre>20</genre>
</audio>
</response>
Source code
XmlDocument allAudio = new XmlDocument();
allAudio.Load(#"e:\Audio.xml");
StreamWriter write_text = File.CreateText(#"e:\Audio.txt");
XmlNodeList audioNodes = allAudio.GetElementsByTagName("audio");
foreach (XmlNode audioNode in audioNodes)
{
XmlNode artistNode = audioNode["artist"];
write_text.WriteLine(String.Format("{0}", artistNode.Value));
}
write_text.Close();
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

Split xml file based on nodes

I have an XML doc which looks roughly like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Multiple xmlns:ns2="someNs2" xmlns="someGenericNs" xmlns:ns4="someNs4" xmlns:ns3="someNs3">
<Single>
<Id>60000</Id>
<Type>Activate</Type>
<Payload>
<ns3:Activation>
<ns3:Parent>
<ns3:TypeId>113</ns3:TypeId>
<ns3:TypeName>TestApplication</ns3:TypeName>
</ns3:Parent>
<ns3:Children>
<ns3:Child>
<ns3:Key>someKey</ns3:Key>
<ns3:ChildTypeName>BadAppType1</ns3:ChildTypeName>
</ns3:Child>
<ns3:Child>
<ns3:Key>someOtherKey</ns3:Key>
<ns3:ChildTypeName>GoodAppType1</ns3:ChildTypeName>
</ns3:Child>
</ns3:Children>
</ns3:Activation>
</Payload>
</Single>
</Multiple>
If the file contains multiple "Child" nodes i would like to split it into more files, 1 file for each existing child node. Something like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Multiple xmlns:ns2="someNs2" xmlns="someGenericNs" xmlns:ns4="someNs4" xmlns:ns3="someNs3">
<Single>
<Id>60000</Id>
<Type>Activate</Type>
<Payload>
<ns3:Activation>
<ns3:Parent>
<ns3:TypeId>113</ns3:TypeId>
<ns3:TypeName>TestApplication</ns3:TypeName>
</ns3:Parent>
<ns3:Children>
<ns3:Child>
<ns3:Key>someOtherKey</ns3:Key>
<ns3:ChildTypeName>GoodAppType2</ns3:ChildTypeName>
</ns3:Child>
</ns3:Children>
</ns3:Activation>
</Payload>
</Single>
</Multiple>
And then a new XmlDoc containing the other "Child" node. Can this be achieved through LINQ?
My code so far is:
private bool HasMoreThanOneChild(string xml) {
XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);
if (doc.GetElementsByTagName("ns3:Child").Count > 1)
{
return true;
}
return false;
}
public List<string> DoSomething(XmlDocument doc){
if(HasMoreThanOneChild(doc.InnerXml))
return Split(doc);
}
I returned a List there because I'm more interested in the "InnerXML" once the doc is split. But I am at a loss of how to implement this split, if it is possible.

XNamespace ns="someNs3";
//get all Child elements
var childElements=doc.Descendants().Elements(ns+"Child").ToList();
//remove those child elements
doc.Descendants().Elements(ns+"Child").ToList().ForEach(x=>x.Remove());
int i=1;
foreach(var child in childElements)
{
//add that child to children element
doc.Descendants().Elements(ns+"Children").First().Add(child);
//save it to new file!
doc.Save("file"+i+".xml");
doc.Descendants().Elements(ns+"Child").ToList().ForEach(x=>x.Remove());
i++;
}

Reading an innertext from an xml document

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!
http://www.dotnetcurry.com/ShowArticle.aspx?ID=564
for your answer(i havnt tried it though try by changing like this in ur code)
doc.SelectSingleNode("soap/ProcessResp/ Result/OverallResult/text()").InnerText;
