[MarkLogic Dev General] MarkLogic XQuery Tag Library and JSTL XML Tag Library

Tue Apr 3 15:45:29 PDT 2007

I'd like to be able to use these two libraries so that I can grab XML  
data from Mark Logic and then parse it using the JSTL XML libraries.

Here's what I've got so far.  Use xq:execute to populate "results"  
variable with documents.  Iterate over "results" and pass each result  
converted to a string to x:parse, storing the parsed result in  
variable "art"

But then when I try to access any elements of "art" I get a  
SAXPathException.

Not sure what's happening but I'm new to using both tag libraries  
so ....

Thanks in advance ...
