Delete a whole element in a XML-File

As i said in the Title: I want to Delete a whole element in a Xml-File with c# if the value of an attribute of this element is preRequisite.

XML File :

<dependency>
<dependentAssembly dependencyType="preRequisite"></dependentAssembly>
</dependency>

<dependency>
<dependentAssembly dependencyType="install"></dependentAssembly>
</dependency>

current Code:

using (XmlReader reader = XmlReader.Create(filePath))//filepath is just a normal Path
{
    while (reader.Read())
    {
        if (reader.Name == "dependentAssembly" && reader.GetAttribute("dependencyType") != "preRequisite")
        {
        //here shall it delete the Element "dependency"
        }
    }
}

At the place where i set the command it shall delete the Element "dependency"

i tried many things but i dont get how i shall delete this Element

You can achieve this using LINQ to XML:

var xml = XElement.Load(File.OpenRead(@"XmlLocation"));

var elementsToDelete =
    xml.Descendants("dependentAssembly")
       .Where(x => x.Attribute("dependencyType") != null && 
                   x.Attribute("dependencyType").Value != "preRequisite");

foreach (var xElement in elementsToDelete)
{
    xElement.Remove();
}
