Adding and removing XDocument elements and their childs with LINQ

I've been coding a program that uses XDocument to write XML files. The structure of the test program is:

<SchoolData storeName="mikveIsrael" location="mikve">
    <employee id="1">
        <personalInfo>
            <name>Ilan Berlinbluv</name>
            <zip>58505</zip>
        </personalInfo>
        <employeeInfo>
            <salary>5000</salary>
            <id>1</id>
        </employeeInfo>
    </employee>
    <employee id="2">
        <personalInfo>
            <name>Noam Inbar</name>
            <zip>58504</zip>
        </personalInfo>
        <employeeInfo>
            <salary>4500</salary>
            <id>2</id>
        </employeeInfo>
    </employee>
    <employee id="3">
        <personalInfo>
            <name>Adi Raiten</name>
            <zip>58503</zip>
            </personalInfo>
        <employeeInfo>
            <salary>5000</salary>
            <id>3</id>
        </employeeInfo>
    </employee>
</SchoolData>

So far, my test program writes that to Employee.xml on my desktop. I can also read the data from XML using XDocument.Load(), and parse different information. However I don't know how to add or remove elements (the element I want to add is <employee>, which contains all the elements such as name and such. Can someone point me in the right direction on how this is done?

Adding elements to XML is pretty straightforward. Using the right indentation you can even see the XML structure in your code:

XDocument doc = XDocument.Load(fileName);

doc.Root.Add(new XElement("employee", new XAttribute("id", 42),
                 new XElement("personalInfo",
                     new XElement("name", "Arthur Dent"),
                     new XElement("zip", "00000")),
                 new XElement("employeeInfo",
                     new XElement("salary", 0),
                     new XElement("id", 3))));

doc.Save(fileName);
