Re: [xsl] Highlight.js available as a XPath extension function

["Christophe Marchand cmarchand@xxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Until Java8, JDK had a JS evaluator embeded. Since Java9, it's an 
optional module - just like JaxB, and you can choose between various 
implementations. I use GraalJS[1] for this.

In extension function, GraalJS is started only once, and reused at each 
call, but it's still quite heavy...
