vb.net - 读取 Xml 文件并在流文档中将单词加粗

Question

将以下文本放置在 XAML 中流文档段落的内联中，会使单词“charge”变为粗体。但是使用 xmlreader.ReadInnerXml 从 xml 文件中读取相同的文本什么也不做。

离子和电子对这种电荷流动的电阻导致等离子体的欧姆加热。

如何使单词变粗？

     paragraph.Inlines.Add(b)
     flowdocument.Blocks.Add(paragraph)
     flowdocumentscrollviewer.Document=flowdocument

部分xml文件：
