ParseRSS mainly has two main objects. RSSFeedObject and RSSItemObject. You can create your own parsing strategy by implementing RSSFeed and RSSItem.

Usage

ParseRSS depends on XmlPullParser, so feed it at least once in a lifetime. First thing first, the initialization part. You can put it on your Application onCreate function.

ParseRSS.init(XmlPullParserFactory.newInstance())

Be aware that XmlPullParser could throw an exception even in initialization step.

Next, feed the RSS string into ParseRSS

val feed: RSSFeedObject = ParseRSS.parse(xml)
feed.items.forEach {
  print(it.title)
}

ParseRSS as a Converter

ParseRSS does not have its own networking mechanism. Instead, it benefits from infamous networking library such as Retrofit, and Fuel. By using ConverterFactory, ParseRSS is ready to ship without breaking your project design pattern.

Fuel

Convert Fuel Response into RSSFeed by using responseRss function.

Fuel.get(URL).responseRss<RSSFeedObject> { result ->
  result.fold({ feed ->
    feed.items.forEach {
      print(it.title)
    }
  }, { error ->
    print(error)
  })
}

Retrofit

Convert Retrofit Response into RSSFeed by using ParseRSSConverterFactory

interface MyRssService {
    @GET("rss")
    fun rss(): Call<RSSFeedObject>
}

val retrofit = Retrofit.Builder()
    .addConverterFactory(ParseRSSConverterFactory.create<RSSFeedObject>())
    .baseUrl(BASE_URL)
    .build()

val rssService = retrofit.create(MyRssService::class.java)
rssService.rss().enqueue(object : Callback<RSSFeedObject> {
    override fun onFailure(call: Call<RSSFeedObject>, t: Throwable) {
    }
    override fun onResponse(call: Call<RSSFeedObject>, response: Response<RSSFeedObject>) {
    }
})

Gradle Dependency

Add jitpack repository in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}
