how to get child node value in xml using c#

Recently i need to get specific child node values from XML string in C#.

After spending some time i found a best way to parse the xml string to objects.

step 1 :
Include namespace
using System.Linq;

step 2:
Load xmlstring to XDocument, mean parse the string XDocument

step 3:
By using linq with Descendants you can read specific child node values from xml string.

READ CHILD NODES VALUES FROM XML WITH EXAMPLE

string s = @"<Root>
<Persons>
<Person ID=""1"">
<Name>Mishal</Name>
<Phone>860 9555 788</Phone>
<Email>abc@ac.com</Email>
</Person>
<Person>
<Name>Andy</Name>
<Phone>866 9555 788</Phone>
<Email>abc@abc.com</Email>
</Person>
</Persons>
</Root>";

XDocument xmlString = XDocument.Parse(s);

var root = (from obj in xmlString.Descendants("Person")
select new
{
Name = (string)obj.Element("Name"),
Phone = (string)obj.Element("Phone"),
Email = (string)obj.Element("Email")
}).ToList();

how to load xml string to xdocument

Today i have faced a situation that have to load xml string to XDocument.

But the Load method of XDocument doesn't support the string as a input parameter.

XDocument has another method called XDocument.Parse(xml), this method will accept xml string and parse them into an XDocument.

Example

string xmlString=

@"<Root>

<ChildNode1>Value 1</Child>

<ChildNode2>Value 2</Child>

<ChildNode3>Value 3</Child>

</Root>";

XDocument xdocObj= XDocument.Parse(xmlString);

Console.WriteLine(xdocObj);

Hope this note sorted out your search on this issue.

1. What is Angular?

Angular 4 is a JavaScript framework which helps us to build web applications and apps in JavaScript, html, and Typescript, which is a superset of JavaScript.

Angular provides built-in features for animation, http service, and materials which in turn have features such as auto-complete, navigation, toolbar, menus, etc.

The code is written in Typescript, which compiles to JavaScript and displays the same in the browser.
