使用React Native解析RSS feed时，如何在description标记内获取description和imageUrl？

Question

这是我试图解析的RSS提要中的item看起来像：

<item>
<title>
Former cop gets 18 years in prison for shooting civilian to death
</title>
<description>
<![CDATA[
<a href="https://e.vnexpress.net/news/news/former-cop-gets-18-years-in-prison-for-shooting-civilian-to-death-4020110.html"><img width=130 height=100 src="https://i-english.vnecdn.net/2019/11/30/phuoc146331574997301-157508140-8364-4799-1575086150_180x108.jpg" ></a></br>A Dong Nai court sentenced a former traffic policeman to 18 years in prison on Friday for fatally shooting a man in a family feud.

这是我从RSS提要中获取title的方式，我正在使用react-native-rss-parser（https://www.npmjs.com/package/react-native-rss-parser）：

fetch('https://vnexpress.net/rss/tin-moi-nhat.rss')
     .then((response) => response.text())
     .then((responseData) => rssParser.parse(responseData))
     .then((rss) =>  { 
         this.setState(prevState => ({
             ...prevState,

             title0: rss.items[0] ? rss.items[0].title : '',
             caption0: rss.items[0] ? rss.items[0].description : ''
         }))    
     })

const Feeds = ([
        {
        pic: require('../assets/images/image.jpg'), 
        title: this.state.title0,
        caption: this.state.caption0
      },
])

我正在尝试解析嵌套在描述标签内的description和imageUrl。我该怎么做？有什么建议吗？
