I want to print the "value" Computer into my console. but I'm unable to find proper resources as I don't know the terminology that is needed to search, like nodes, child, values, ecc..
My current code:
XDocument xml = XDocument.Load(Localization);
XElement pattern = xml.XPathSelectElement("/resources/string[@key=\"Example\"]");
Xml:
<resources xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<string key="Example">Computer</string>
</resources>
What can I do to print that value?
You are getting an XElement object from xml.XPathSelectElement(). In The XElement class, there is a property called Value which will return the enclosing text (string) within an element.
The following code will print out what you desired:
XDocument xml = XDocument.Load(Localization);
XElement pattern = xml.XPathSelectElement("/resources/string[@key=\"Example\"]");
Console.WriteLine(pattern.Value);
Console output:

XML/HTML can be viewed as a tree of nodes (element) and children of nodes.

Document is the parent of Root ElementRoot Element is a child of Document<head> are <html> and Document (think family tree)Document are all the children nodes including nested children<head> is a sibling to <body>The XElement class allows you to traverse other nodes that are related to the current node.
XPath allows you to easily traverse the XML tree using a string.

You do not need xpath with xml linq. Use a dictionary to get all key values
XDocument doc = XDocument.Load(FILENAME);
Dictionary<string, string> dict = doc.Descendants("string")
.GroupBy(x => (string)x.Attribute("key"), y => (string)y)
.ToDictionary(x => x.Key, y => y.FirstOrDefault());
