Silverlight RichTextBox中的XAML标记大小过大

我在silverlight 5应用程序中有一个非常简单的RichTextBox控件

<RichTextBox x:Name="rtbControl" 
    Height="Auto" 
    ContentChanged="rtbControl_ContentChanged" />

一切顺利。然而，如果我只键入几个单词并检查

标记，它将是巨大的！下面是一个片段。有没有办法不让所有的排版内容都出现在标记中？它为什么在那里，需要它吗？有没有办法把它去掉

<Section xml:space="preserve" HasTrailingParagraphBreakOnPaste="False" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">

</Run><Run>blah? or </Run></Paragraph></section>

这是个坏消息吗
废话？或

我想我会分享我的解决方案来帮助他人。。。它已经存在好几个月了，我没有看到任何不良副作用

我创建了一些扩展方法来帮助删除排版属性

public static class RichTextBoxExtensions {
        // <summary>
        /// Removes any xml tag with the prefix given from a string
        /// </summary>
        /// <param name="XMLString"></param>
        /// <param name="TagPrefix"></param>
        /// <returns></returns>
        public static string RemoveXMLAttributesFromNode(this string XMLString, string prefix)
        {
            //Match [Prefix][any number of Not =][=]["][any number of Not "]["][ ] <-must have space!!!
            string replace = prefix + "[^\\=]*=\"[^\"]*\" ";
            return Regex.Replace(XMLString, replace, string.Empty);
        }
        /// <summary>
        /// Removes any xml tag with prefixed by an element in unWanted
        /// </summary>
        /// <param name="XMLString"></param>
        /// <param name="TagPrefix"></param>
        /// <returns></returns>
        public static string RemoveXMLAttributesFromNode(this string XMLString, List<string> unWanted)
        {

            foreach (string prefix in unWanted)
            {
                //Match [Prefix][any number of Not =][=]["][any number of Not "]["][ ] <-must have space!!!
                string replace = prefix + "[^\\=]*=\"[^\"]*\" ";
                XMLString = Regex.Replace(XMLString, replace, string.Empty);
            }
            return XMLString;
        }

//匹配[Prefix][anynumber of Not=][=][][“][any number of Not”][][“][]哇，太大了：（我认为持久化需要确保您获得准确的格式。您想做什么？也许您可以使用文本或选定的文本属性？请参阅此官方示例。我为用户提供了创建文档片段的能力，我需要为他们提供富文本格式功能。用户输入将推送到数据库。我确实需要现在，用户可以在3行中键入4个单词，并且已经有4000多个字符的文本。我看到了两种减少内容大小的方法：压缩和解析XML以删除段落和公司的所有默认属性。但是我没有看到内置解决方案，抱歉。
