请问怎么实现使用jacob拷贝一个文档的部分内容（不是段落）到另一个文档中保存？

开发四年只会写业务代码，分布式高并发都不会还做程序员？->>>   

之前有试过有itext读取文档内容然后截取，取得我想要的内容但取到的内容是没有格式的，格式的丢失让我想到用jacob的copy、paste方法，但由于我只找到拷贝单一段落或是全文的方法，这个不是我要的效果，我只想取得文档里面的部分内容，请问有人做过类似的或是有什么好的想法吗？

//这是copy全文方法
ComThread.InitSTA();
 //被复制的文档
ActiveXComponent word2= new ActiveXComponent("Word.Application");
word2.setProperty("Visible", new Variant(false));
Dispatch documents2 = word2.getProperty("Documents").toDispatch();
//复制的文档
ActiveXComponent word= new ActiveXComponent("Word.Application");
word.setProperty("Visible", new Variant(false));
Dispatch documents = word.getProperty("Documents").toDispatch();
doc2 = Dispatch.call(documents2, "Open", saveNewRealpath).toDispatch();
//复制模板的内容
doc= Dispatch.call(documents, "Open",fileRealPath).toDispatch();
Dispatch wordContent = Dispatch.get(doc, "Content").toDispatch();
			      	
/*Dispatch paragraphs = Dispatch.get(doc2, "Paragraphs").toDispatch();
 Dispatch paragraph = Dispatch.call(paragraphs, "Item",new Variant(40)).toDispatch();
Dispatch range = Dispatch.get(paragraph, "Range").toDispatch();
Dispatch.call(range, "Copy");*/
Dispatch.call(wordContent, "Copy");
Dispatch selection = Dispatch.get(word2, "Selection").toDispatch(); 
Dispatch textRange = Dispatch.get(selection, "Range").toDispatch();
Dispatch.call(textRange, "Paste");
Dispatch.call(doc2, "Save");
Dispatch.call(doc2, "Close", new Variant(true));
Dispatch.call(word2, "Quit");
doc2 = null; 
word2 = null;
Dispatch.call(doc, "Close", new Variant(true));
Dispatch.call(word , "Quit");
doc = null; 
word  = null;
documents2 = null;
