我是用的代码是：

 Word.Application app = new Word.Application();
        //模板文件
        string TemplateFile = "";//@"E:\work\testPrint.doc";

　　...............

//模板文件拷贝到新文件
        File.Copy(TemplateFile, FileName);
        Word.Document doc = new Word.Document();
        object Obj_FileName = FileName;
        object Visible = false;
        object;
        object missing = System.Reflection.Missing.Value;
        //打开文件
        doc = app.Documents.Open(ref Obj_FileName, ref missing, ref ReadOnly, ref missing,
            ref missing, ref missing, ref missing, ref missing,
            ref missing, ref missing, ref missing, ref Visible,
            ref missing, ref missing, ref missing,
            ref missing);
        doc.Activate();

        foreach (Word.Bookmark bm in doc.Bookmarks)
        {
            if (bm.Name == "title")
            {
                bm.Select();
                bm.Range.Text = title;
            }
            else if (bm.Name == "content")
            {
                bm.Select();
                //bm.Range.Text = Comm.StripHTML(content);
                bm.Range.Text = content;
            }
          
        }

我的问题是： 导出的内容中有很多word标签。像"<span>","<P>","<?xml:namespace>"这样的东西。这个问题怎么解决啊！
