Populate XDocument from String - c#

I'm working on a little something and I am trying to figure out whether I can load an XDocument from a string. XDocument.Load() seems to take the string passed to it as a path to a physical XML file.
I want to try and bypass the step of first having to create the physical XML file and jump straight to populating the XDocument.
Any ideas?


You can use XDocument.Parse for this.


You can use XDocument.Parse(string) instead of Load(string).


How about this...?
TextReader tr = new StringReader("<Root>Content</Root>");
XDocument doc = XDocument.Load(tr);
Console.WriteLine(doc);
This was taken from the MSDN docs for XDocument.Load, found here...

Try the Parse method.

Copy or clone a specific Element from XML to the same XML

i want to copy or clone a specific node or Element from XML. I tried many codes, but no one worked. I am program with C#.
Here is my XML, I hope my problem is clear!
This is my XML before
I want this XML
I can´t do this manually, because I need more than 30 Tools more.

it really depends on what you are using to parse the xml.
I will give you info for the two most used classes for parsing an xml in .NET.
XmlDocument: then you can use .CloneNode
XDocument: then you can do something like this:
XElement toCopy = ...;
XElement copy = XElement.Parse(toCopy.ToString());
If you are not familiar with xml processing in .NET, there is enough information in msdn for XDocument and XmlDocument.

C# how to fill xml file with string value

For example, my string is:
<Here>
<Hey>smth</Hey>
<Hi>else</Hi>
</Here>
I want my document x.xml to have that content. I tried
xmlDoc.InnerXml = thatString;
but it throws an exception.

Try,
XElement here = XElement.Parse("<Here><Hey>smth</Hey><Hi>else</Hi></Here>");
Then to save it to a file.
here.Save("filePath");

XmlDocument.LoadXml

even better - use linq to xml. i prefer the XDocument class of XmlDocument

I beleive your code is for reading only. You have to use XmlTextWriter instead.

Quickest way to generate xmldocument object from xml file

whats the quickest way to generate an XmlDocument object from a file. Im working on the basis that i know my xml is well formed, and ideally im looking for a method that will allow me to simply pass in a string as my file location, and return a complete XmlDocument object.

Um, XmlDocument.Load?
XmlDocument document = new XmlDocument();
document.Load(filename);
On the other hand, if you're using .NET 3.5 or higher you should strongly consider moving to LINQ to XML and XDocument instead:
XDocument doc = XDocument.Load(filename);
LINQ to XML is a much nicer XML API.

The quickest way would be:
string pathToXmlFile = //your path;
XmlDocument document = new XmlDocument();
document.Load(pathToXmlFile);

C# XML conversion

I have a string containing fully formatted XML data, created using a Perl script.
I now want to convert this string into an actual XML file in C#. Is there anyway to do this?
Thanks,

You can load a string into an in-memory representation, for example, using the LINQ to SQL XDocument type. Loading string can be done using Parse method and saving the document to a file is done using the Save method:
open System.Xml.Linq;
XDocument doc = XDocument.Parse(xmlContent);
doc.Save(fileName);
The question is why would you do that, if you already have correctly formatted XML document?
A good reasons that I can think of are:
To verify that the content is really valid XML
To generate XML with nice indentation and line breaks
If that's not what you need, then you should just write the data to a file (as others suggest).

Could be as simple as
File.WriteAllText(#"C:\Test.xml", "your-xml-string");
or
File.WriteAllText(#"C:\Test.xml", "your-xml-string", Encoding.UTF8);

XmlDocument doc = new XmlDocument();
doc.Load(... your string ...);
doc.Save(... your destination path...);

Problem with node.GetElementsByTagName in C#

I have a really simple XML file that I'm trying to read, but I can't seem to get it working. Here is the XML file:
<?xml version="1.0"?> <Results><One>45364634</One><Two>-1</Two><Three>B</Three></Results>
I am trying to get the contents of two like this:
XmlNode node = doc.DocumentElement.SelectSingleNode("/Results/Two");
or
XmlNodeList list = doc.GetElementsByTagName("Two");
Neither is working. When I copy paste the XML as a string into the XmlDocument, then it works. However, when I use the string I pull out of the response (where I'm getting the XML from), it doesn't work.
I'm wondering if it's something weird like a character issue or not looking at the correct root, but I can't figure it out. Any ideas?
Thanks!

Check the Xml file encoding ...
Is it ansi? utf-8 or utf-16?
Check if the xml was loaded from the file at all. Check if there is any error, see if the document was populated.
I think the document is not being populated when loading from the file.

By your use of the word "response" I am assuming you are passing the xml via http? If so, try using HttpServerUtility.HtmlDecode( xml ) see if that works

Bleh.
Turns out I was returning an XML document within an XML document. That's why printing to the screen looked ok but I couldn't pull it out.
Thanks guys.
