Hi
Thanks for your request. I think you should use DocumentVisitor in this case. Please see the following code:

public static void main(String[] args) throws Exception
{ 
    License license = new License();
    license.setLicense("Aspose.Words.lic");
    //Open document
    Document doc = new Document("C:\\Temp\\in.doc");
    EmptyParagraphRemover remover = new EmptyParagraphRemover();
    doc.accept(remover);
    //Save output document
    doc.save("C:\\Temp\\out.doc");
}

//---------------------------------------------------------------------------------------

import com.aspose.words.DocumentVisitor;
import com.aspose.words.Paragraph;
import com.aspose.words.VisitorAction;
public class EmptyParagraphRemover extends DocumentVisitor
{
    /// 
    /// Called when visiting of a Paragraph node is Started in the document.
    /// 
    public int visitParagraphStart(Paragraph paragraph)
    {
        if (!paragraph.hasChildNodes())
        {
            try
            {
                paragraph.remove();
            }
            catch (Exception ex) { System.out.println(ex); }
        }
        return VisitorAction.CONTINUE;
    }
}

Hope this helps.
Best regards.*

I get null pointers if I attempt to do this while I am still building my document.

I need a way of saying, “If the last line of the document is a blank line, remove it.” At that point, I need to continue writing.
