I have an XML string where some nodes have text between the tags, like so:
<note>
<to>Text between tags</to>
<from>More text</from>
<empty />
</note>
In Scala, how can I remove the text between these tags so that I get a string like this?:
<note><to></to><from></from><empty /></note>
You can use a RewriteRule for this and set Text nodes to Empty e.g.
val removeText = new RewriteRule {
override def transform(n: Node): NodeSeq = n match {
case e: Text => NodeSeq.Empty
case _ => n
}
}
Then you can use RuleTransformer to transform your XML e.g.
val source = scala.io.Source.fromFile("myData.xml")
val lines = try source.mkString finally source.close()
val xml = XML.loadString(lines)
val output = new RuleTransformer(removeText).transform(xml)
println(output)
Output:
<note><to/><from/><empty/></note>
