In the previous post, you learned how to create an xml file from a collection of Book objects with Linq. Save("d:/data.xml"); To delete an element from the xml file, you need to select the element based on your conditions. However, we don't guarantee all things of the web are accurate.

Now, you will learn how to read, add, edit, and delete elements of the xml file that is stored in your computer. Then you will use the Remove method of the XElement class to delete that element. If you find any error, please report it then we will take actions to correct it as soon as possible.

Map Path("data.xml")); var items = from item in xml Doc. It seems to me there should be better usage guidelines.

I got stuck at the very first point of it i.e i cant grab the value from xml file using linq. , which only contains 2 strings, name and description. Then I populate a new list, which contains many of the same names, but some of them contains descriptions that the other list did not contain.
