Variable in CDATA in Scala

Question

Is there a way to put a variable to be expanded in a cdata section in scala

val reason = <reason><![CDATA[ {failedReason} ]]></reason>

Answer 1

It could be even simplier:

val reason = <reason>{scala.xml.PCData(failedReason)}</reason>

Answer 2

I am not sure if you can get that through native XML support, but you could do something like:

scala.xml.XML.loadString("<reason><![CDATA[%s]]></reason>".format(failedReason))

You lose some of the compile-time validations that way, but it should give you am xml element with the data which you are looking for. Since it returns a scala.xml.Elem, you can also embed the result in a larger XML structure.

EDIT

After thinking about this a bit more, the following may be a beter (and less fragile) way to do this. It restricts the free-text portion to only the CDATA, minimizing the potential for unbalanced expressions.

<reason>{ scala.xml.Unparsed("<![CDATA[%s]]>".format(failedReason)) }</reason>
