In this post LINQ to XML Delete Elements, we
shall see how to delete elements in an existing XML structure. We will load an
XML file from the disk, remove the elements and save the updated XML to the
disk.
Assume that we have the following XML fragment
<Employees>
<Employee>
<Name>
<FirstName>Henry</FirstName>
<LastName>Ford</LastName>
</Name>
<Age>60</Age>
<Department Name="Automobile" />
</Employee>
<Employee>
<Name>
<FirstName>Bill</FirstName>
<LastName>Gates</LastName>
</Name>
<Age>55</Age>
<Department Name="Software" />
<Department Name="Software" />
</Employee>
<Employee>
<Name>
<FirstName>Steve</FirstName>
<LastName>Jobs</LastName>
</Name>
<Age>75</Age>
<Department Name="i-Phone" />
<Department Name="i-Phone" />
</Employee>
</Employees>
Now
we will remove the Element, for the Employee Steve Jobs.
XElement xEmp = XElement.Load(@"D:\Employees.xml");
//
var empDetails = from
emps in xEmp.Elements("Employee")
where
emps.Element("Name").Element("FirstName").Value.Equals("Steve")
select
emps;
//
empDetails.First().Remove();
//
xEmp.Save(@"D:\Employees.xml");
When
this code is executed, the Employees.xml file will contain
the following tags.
<Employees>
<Employee>
<Name>
<FirstName>Henry</FirstName>
<LastName>Ford</LastName>
</Name>
<Age>60</Age>
<Department Name="Automobile" />
</Employee>
<Employee>
<Name>
<FirstName>Bill</FirstName>
<LastName>Gates</LastName>
</Name>
<Age>55</Age>
<Department Name="Software" />
<Department Name="Software" />
</Employee>
</Employees>
That’s it we have deleted an Element in the XML saved the changes to the Disk.
