description在我的 UI 控件中显示内容对我来说非常简单。我可以自己决定我的 UI 外观（字体大小、字体颜色）。

但是，如果我从 Google 检索内容，事情会变得更加困难！

如您所见，description它带有各种 HTML 标签，这不符合我的兴趣。我只对纯内容感兴趣，而不是格式信息。

有什么简单的方法可以实现我的目标吗？

该类Html具有fromHtml()从字符串中删除任何标签的方法：

String noHtml = Html.fromHtml(HTML_STRING).toString();

见这里： http: //developer.android.com/reference/android/text/Html.html#fromHtml(java.lang.String)

您可以使用 XSLT 将 xml 输入转换为 xml 输出，在这种情况下，您将创建一个匹配描述的模板匹配器，然后仅将文本复制到输出中，直到描述标记结束。
