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

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

Highlight JS is a well known javascript library that is able to 
highlight source code in a HTML page.

If you need to generate a static HTML that contains highlighted source 
code, and if you use Saxon 10 and Java 11 at least, you now have a XPath 
extension function that do this. It embeds highlight.js library, and so, 
rendering is the same as the one done in browser. But your page is 
generated and do not require JavaScript, and so can be used as source in 
multiple renderers, as FlyingSaucer[0] or forks.

highlightJS-saxon-extension is available in maven 
<https://repo1.maven.org/maven2/top/marchand/xml/saxon/extension/highlight/1.00.01/>[1], 
and source code is on github 
<https://github.com/cmarchand/highligtJS-saxon-extension>[2].

A XSL sample is available in unit tests : 
https://github.com/cmarchand/highligtJS-saxon-extension/blob/master/src/test/xsl/top/marchand/xml/saxon/extension/highlight/formater.xsl[3] 
with data 
<https://github.com/cmarchand/highligtJS-saxon-extension/blob/master/src/test/xml/top/marchand/xml/saxon/extension/highlight/source-code.xml>[4], 
and java samples 
<https://github.com/cmarchand/highligtJS-saxon-extension/blob/master/src/test/java/top/marchand/xml/saxon/extension/highlight/HighlightExtensionTest.java#L60>[5] 
to configure Saxon are available.

Enjoy,
Christophe
