对我来说，在我的UI控件中显示description的内容非常简单。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！

这是一个例子

正如您所看到的，description附带了各种HTML标记，这不符合我的兴趣。我只关注普通内容，而不是格式化信息。

有什么简单的方法可以实现我的目标吗？

Answer 1

Html类使用fromHtml()方法从字符串中删除任何标记：

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

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

Answer 2

您可以使用XSLT将xml输入转换为xml输出，在这种情况下，您将创建与描述匹配的模板匹配器，然后从此开始只将文本复制到输出中，直到描述标记结束。

从RSS新闻描述标记中删除HTML格式信息
