推荐答案

您可能希望阅读 ^ ]博客文章，其中详细介绍了如何使用支持XAML到HTML和HTML到XAML的数据绑定RichTextBox.

基本上，它是通过将HTML(在可能的情况下)转换为XAML来工作的.表面上HTML类似于XML，但事实并非如此-唯一真正的相似之处在于它们都支持标签和<>人物.由于HTML在格式上不如XML严格，因此无法使用XSL进行转换.

You may want to have a read of this[^] blog post from Michael Sync which details how to work with a databound RichTextBox that supports XAML to HTML and HTML to XAML.

Basically, it works by converting the HTML (where it can) into XAML. Superficially HTML resembles XML, but it''s not - the only real resemblance is that they both support tags and the <> characters. As HTML is not as strict in its well-formed nature as XML, it cannot be converted using XSL.
