问：

问题：

我在尝试解析此页面以查找包含图像链接的外壳 xml 标记时遇到问题。

https://store.steampowered.com/feeds/news/app/1348750/?cc=US&l=english&snr=1_2108_9__2107

我使用的是 Unity 和 C#，我以编码的 UTF-8 字符串或从 unitys UnityWebRequest.Get 方法的原始 byte[] 中获取数据。

当保存到文件或打印到文本框时，似乎很多数据都是混乱的。

我相信数据应该是 XHTML，我不确定如何将其转换为可读格式以开始解析 URL。

期望：

      <title>Update v1.3</title>
      <description>Changelog:&lt;br&gt;&lt;ul class=&quot;bb_ul&quot;&gt;&lt;li&gt;Arry and Miri can now gain affection.&lt;br&gt;&lt;/li&gt;&lt;li&gt;The player can now view Arry and Miri's epilogue scenes. (You will have to answer their proposal one more time.)&lt;br&gt;&lt;/li&gt;&lt;li&gt;The Arry and Miri achievements have been fixed and should unlock when you reach the epilogue.&lt;br&gt;&lt;/li&gt;&lt;li&gt;The ability management backend has been 100% REDONE, and all associated bugs should be fixed.&lt;br&gt;&lt;/li&gt;&lt;li&gt;Specifically, ability use counts and levels will no longer reset if they're no longer in a player preset.&lt;/li&gt;&lt;/ul&gt;&lt;br&gt;&lt;div class=&quot;bb_h2&quot;&gt;ACTION REQUIRED:&lt;/div&gt;If you take one thing from this update, it's that &lt;b&gt;Arry and Miri's&lt;/b&gt; conversation lines were &lt;b&gt;broken&lt;/b&gt; before this update, with all their epilogue scenes being &lt;b&gt;hidden&lt;/b&gt;. &lt;br&gt;&lt;br&gt;&lt;b&gt;If you've been stuck at their proposal, doing it one more time should unlock their achievements and lead you to their epilogue scenes.&lt;/b&gt;&lt;br&gt;&lt;br&gt;Additionally, I've begun work on the logbook! It's coming along nicely.&lt;br&gt;&lt;br&gt;&lt;img src=&quot;https://i.imgur.com/FBdDow9.png&quot; /&gt;</description>

实际：

这些只是数据中的片段，顶部是它能够显示的一些 HTML，底部看起来像 XML 部分或 XHTML？
