[parenscript-devel] How to generate element[i].childNodes[0].nodeValue

[Wout Perquin]

Hi Scott,
ps:@ does the job.
(ps:ps (let ((var (ps:@ (aref (ps:@ (aref element i) :child-node)
0) :node-value))))) 
renders : "var var = element[i].childNode[0].nodeValue;" exactly what I
wanted.
Concerning the DOT implementation, it was merely a reflection but has
now become some kind of a challenge.  Will think about it.
Will have a look into your suggestion for :USE parenscript.
Thanks, Wout
