Scala library to easily and efficiently process large xmls with repetatively occuring elements. The library is using Stax2 to parse and stream xml.
Following example demonstrates usage with support of scala-xml to read repetative elements.
Example xml:
<?xml version="1.0" encoding="UTF-8"?>
<breakfast_menu>
<food>
<name>Belgian Waffles</name>
<price>$5.95</price>
</food>
<food>
<name>Strawberry Belgian Waffles</name>
<price>$7.95</price>
</food>
</breakfast_menu>Scala:
import scala.util.Using
import scala.jdk.CollectionConverters._
val xmlInputStream: InputStream = ???
val names = Using(new Garook().parse(xmlInputStream, new ExactLocalPathMatcher("breakfast_menu.food"))) { iterator =>
iterator.asScala.map(elem => XML.load(new ByteArrayInputStream(elem)))
.map(_ \\ "name")
.map(_.text)
.toList
}.get
println(names.mkString(", "))
prints
Belgian Waffles, Strawberry Belgian Waffles
