Using play's wsclient to make a call to fetch a RSS feed and return a collection - scala

Question

I am making a request to a URL to grab the RSS xml data:
val items: List[Item] = ws.url("http://www.example.com/rss.xml").get().map { response =>
}
Now I want to loop through all the nodes and create a collection of Items.
My Item case class is:
case class Item(title: String, link: String, description: String, guid: String)
The format of the XML is like below:
<rss ...>
<channel>
<title>
</title>
<link />
<description />
<item>
<title>hello</title>
<description> ... </description>
<guid> ... </guid>
</item>
<item>
...
</item>
</channel>
</rss>
I'm not sure what to do with the response in the call to .map to iterate through the items and how to return a collection of Item case classes.

Answer 1

You should basically use the xml api to extract the relevant NodeSeq, which works like any collection.
Then you map each node to extract the relevant subtag content and create an object out of it.
val itemNodes = response.xml \\ "item" //will get all item nodes as a NodeSeq
val item = itemNodes.map(node =>
Item(
(node \ "title").text,
"", // there's no link tag in the item
(node \ "description").text,
(node \ "guid").text
)
)
If not exactly this, something similar
