How to edit and delete the data stored in xml file using C# and visual studio 2005 through user input?

For example:
for this xml document...

<MenuRoot>
<Books>
<book>
<title> ABC </title>
<author>DEF</author>
<subject>Projec t Management </subject>
</book>
</Books>
</MenuRoot>

Edit the existing data to become as follow (edit the author part)

<MenuRoot>
<Books>
<book>
<title> ABC </title>
<author>Peter </author>
<subject>Projec t Management </subject>
</book>
</Books>
</MenuRoot>

And I also would like to know how to delete the book info ( or the delete the entire book element) stored inside the file. Thanks!!!
