Re: [xsl] error: At xsl:choose, the value of "" is not a node-set

[Wendell Piez <wapiez at mulberrytech dot com>]

Xiaocun:

I think the problem is with the value of $OrganizationHeader, which you're 
passing into the FixAttribute template. What is it? I'll bet it's not a 
node-set. In other words, my guess is that $header isn't a node-set in the 
XPath inside your starts-with().

Cheers,
Wendell
