I find it amazing that this does anything at all. Are you sure that the
contents of <lxslt:script> are not actually in a CDATA section? The
<Customers> element has no end tag, so the stylesheet isn't well-formed
XML as written; and if that were corrected, I would find it very
surprising if Xalan allowed the Javascript syntax and the XML syntax to
cut across each other in this way.

If you put the script in a CDATA section, of course, then the things
that look like tags just become ordinary character data, and you end up
with a string that looks like unparsed XML - which matches the behavior
you describe as "getting a string instead of a node-list". Of course you
will get unparsed XML if you don't parse it.

There is a deeper question: what on earth inspired you to try and solve
this problem this way? It would be much easier to do it in pure XSLT,
without any Javascript, using the substring() function.
