Re: escaping from CDATA

Hi Steve,

Yes. Create a Document object and use the loadXML() method to parse
the XML string into a document. Return the Document object from the
function (this turns into a node set containing a single root node in
XPath terms). Then you probably want to *copy* that Document with
xsl:copy-of rather than get its value with xsl:value-of.

If the XML string isn't a well-formed XML document (e.g. it's got more
than one 'document element') then you can wrap a start tag and end tag
around it using JavaScript string manipulation.

No, none at all. An XSLT processor sees the two versions as being
exactly the same string.

I hope that helps,
