Re: escaping from CDATA

When you set the $arg variable with:

  <xsl:variable name="arg" select="."/>

it's set to a node set containing the current node.

The equivalent to a node set in Javascript is a NodeList object, so
when you pass $arg to the user:createNodeset() function, the arg
argument in the Javascript is set to a NodeList. The loadXML() method,
on the other hand, is expecting a string.

So either you have to make sure that the kind of value you pass to the
function is a string (by converting it to a string using the string()
XPath function, as you've found), or you have to make sure that your
extension function accepts a NodeList and does something sensible with
it (i.e. gets the string value of the first node in the NodeList).

This is an illustration of the fact that with Javascript extension
functions, the XSLT processor cannot automatically convert the
argument you pass to the extension function to a string because it
doesn't know that the extension function is expecting a string. If you
were using a strongly typed language, on the other hand, then it
could.

I hope that helps,

Jeni
