Shows how to remove all unused custom styles from a document.
Document doc = new Document();

doc.Styles.Add(StyleType.List, "MyListStyle1");
doc.Styles.Add(StyleType.List, "MyListStyle2");
doc.Styles.Add(StyleType.Character, "MyParagraphStyle1");
doc.Styles.Add(StyleType.Character, "MyParagraphStyle2");

// Combined with the built-in styles, the document now has eight styles.
// A custom style is marked as "used" while there is any text within the document
// formatted in that style. This means that the 4 styles we added are currently unused.
Assert.AreEqual(8, doc.Styles.Count);

// Apply a custom character style, and then a custom list style. Doing so will mark them as "used".
DocumentBuilder builder = new DocumentBuilder(doc);
builder.Font.Style = doc.Styles["MyParagraphStyle1"];
builder.Writeln("Hello world!");

Aspose.Words.Lists.List list = doc.Lists.Add(doc.Styles["MyListStyle1"]);
builder.ListFormat.List = list;
builder.Writeln("Item 1");
builder.Writeln("Item 2");

// Now, there is one unused character style and one unused list style.
// The Cleanup() method, when configured with a CleanupOptions object, can target unused styles and remove them.
CleanupOptions cleanupOptions = new CleanupOptions();
cleanupOptions.UnusedLists = true;
cleanupOptions.UnusedStyles = true;


Assert.AreEqual(6, doc.Styles.Count);

// Removing every node that a custom style is applied to marks it as "unused" again. 
// Rerun the Cleanup method to remove them.

Assert.AreEqual(4, doc.Styles.Count);
