Shows how to use of methods of Node and CompositeNode to remove a section before the last section in the document.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.Writeln("Section 1 text.");
builder.Writeln("Section 2 text.");

// Both sections are siblings of each other.
Section lastSection = (Section)doc.LastChild;
Section firstSection = (Section)lastSection.PreviousSibling;

// Remove a section based on its sibling relationship with another section.
if (lastSection.PreviousSibling != null)

// The section we removed was the first one, leaving the document with only the second.
Assert.AreEqual("Section 2 text.", doc.GetText().Trim());
