ElementsAfterSelf();
foreach (XElement el in els)
listBox1.Items.Add(el.Name);
The following is returned:
Element5
Element6
The following approach returns the same results:
IEnumerable re = root.Element("Element4").ElementsAfterSelf();
foreach (XElement el in re)
listBox1.Items.Add(el.Name);
Using the same XML tree, the following code queries the XML tree for those elements that are
before Element4:
XElement re = root.Element("Element4");
IEnumerable els = re.ElementsBeforeSelf();

Chapter 8: Advanced LINQ to XML Programming Topics
foreach (XElement el in els)
listBox1.Items.Add(el.Name);
Again, you could write it as follows:
IEnumerable re = root.Element("Element4").ElementsBeforeSelf();
foreach (XElement el in re)
listBox1.Items.Add(el.Name);
In both cases, the following values are returned:
Element1
Element2
Element3
Last, the overloads for these two methods return the elements after or before the current element that
also match the specified element name:
XElement re = root.Element("Element4");
IEnumerable els = re.
