xml-reader
Xml reader helps to convert xml documents into domain classes.
import nl.elmar.xml.reader._
import XmlPath._
import cats.syntax.cartesian._
case class Author(name: String)
case class Book(title: String, year: Int, author: List[Author])
case class Library(book: List[Book])
implicit val authorReader: Reader[Author] =
__.read[String] map Author
implicit val bookReader: Reader[Book] =
(__ \ "title").read[String] |@|
(__ \ "year").read[Int] |@|
(__ \ "author").read[List[Author]] map Book
val libraryReader: Reader[Library] =
(__ \ "book").read[List[Book]] map Library
libraryReader(
<library>
<book>
<title>Programming in Scala, Third Edition</title>
<year>2016</year>
<author>Martin Odersky</author>
<author>Lex Spoon</author>
<author>Bill Venners</author>
</book>
</library>
)
The same result could have been achieved with:
import nl.elmar.xml.reader._
import GenericReader._
implicit val authorReader: Reader[Author] =
__.read[String] map Author
implicit val bookReader = Reader.reader[Book]
val libraryReader = Reader.reader[Library]
Thanks to davegurnell for his awesome shapeless guide.
