Silverlight RichTextBox中的XAML标记大小过多

概述我在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" /> 随着数据的更改,我将其捕获到局部变量中,如下所示： private void rtbControl_Cont 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" />

随着数据的更改,我将其捕获到局部变量中,如下所示：

private voID rtbControl_ContentChanged(object sender,ContentChangedEventArgs e)    {        RichTextContent = rtbControl.Xaml;    }

一切都有效.但是,如果我输入几个单词并检查<段落>加价,真是太棒了！下面是一个片段.有没有办法在标记中没有所有的排版内容？它为什么存在并且需要它？有没有办法删除它？

<Section xml:space="preserve" HasTrailingParagraphBreakOnPaste="False" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"><Paragraph FontSize="11" FontFamily="Segoe UI" Foreground="#FF000000" FontWeight="normal" FontStyle="normal" FontStretch="normal" CharacterSpacing="0" Typography.AnnotationAlternates="0" Typography.EastAsianExpertForms="False" Typography.EastAsianLanguage="normal" Typography.EastAsianWIDths="normal" Typography.Standardligatures="True" Typography.Contextualligatures="True" Typography.discretionaryligatures="False" Typography.Historicalligatures="False" Typography.StandardSwashes="0" Typography.ContextualSwashes="0" Typography.ContextualAlternates="True" Typography.StyListicAlternates="0" Typography.StyListicSet1="False" Typography.StyListicSet2="False" Typography.StyListicSet3="False" Typography.StyListicSet4="False" Typography.StyListicSet5="False" Typography.StyListicSet6="False" Typography.StyListicSet7="False" Typography.StyListicSet8="False" Typography.StyListicSet9="False" Typography.StyListicSet10="False" Typography.StyListicSet11="False" Typography.StyListicSet12="False" Typography.StyListicSet13="False" Typography.StyListicSet14="False" Typography.StyListicSet15="False" Typography.StyListicSet16="False" Typography.StyListicSet17="False" Typography.StyListicSet18="False" Typography.StyListicSet19="False" Typography.StyListicSet20="False" Typography.CAPItals="normal" Typography.CAPItalSpacing="False" Typography.Kerning="True" Typography.CaseSensitiveForms="False" Typography.HistoricalForms="False" Typography.Fraction="normal" Typography.NumeralStyle="normal" Typography.NumeralAlignment="normal" Typography.SlashedZero="False" Typography.MathematicalGreek="False" Typography.Variants="normal" Textoptions.TextHintingMode="Fixed" Textoptions.textformattingMode="IDeal" Textoptions.TextRenderingMode="auto" TextAlignment="left" lineHeight="0" linestackingStrategy="MaxHeight"><Run>was it a </Run><Run Textdecorations="Underline">bad </Run><Run>blah? or </Run></Paragraph></section>

解决方法 我以为我会分享我的解决方案来帮助别人……它已经存在好几个月了,我还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Typography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,string.Empty);            }            return XMLString;        }

接下来,在我将字符串保存到数据库之前,我删除了不良属性,如下所示：

List<string> badAttributes = new List<string>();        badAttributes.Add("Typography");        var ffText = ffi.FreeFormText == null ? null : ffi.FreeFormText.RemoveXMLAttributesFromNode(badAttributes);

在删除这些属性后重新渲染RTF时,我没有看到任何问题.希望这个解决方
