package pull

Classes needed to view an XML document as a series of events. The document is parsed by an scala.xml.pull.XMLEventReader instance. You can treat it as an scala.collection.Iterator to retrieve the events, which are all subclasses of scala.xml.pull.XMLEvent.

scala> val source = Source.fromString("""1.0" encoding="UTF-8" standalone="yes"?>
customvalue"?>
BAR">
]>Hello&bar;>""")

source: scala.io.Source = non-empty iterator

scala> val reader = new XMLEventReader(source)
reader: scala.xml.pull.XMLEventReader = non-empty iterator

scala> reader.foreach{ println(_) }
EvProcInstr(instruction,custom value="customvalue")
EvText(
)
EvElemStart(null,foo,,)
EvText(Hello)
EvComment( this is a comment )
EvElemStart(null,bar,,)
EvText(BAR)
EvElemEnd(null,bar)
EvElemStart(null,bar,,)
EvEntityRef(gt)
EvElemEnd(null,bar)
EvElemEnd(null,foo)
EvText(
