Re: [Exist-open] Stumped... Namespace issue>

[Mike S. <so...@if...>]

I couldn't see the bold in your plain text e-mail, but I'm guessing you 
get a namespace declaration error in "eval".  I'm pretty sure you need 
to add your namespace declaration to the string you are evaluating, like:

let $nsdecl = 'declare namespace ms="http://myNamespace/1.1/"; '
...
util:eval (concat ($nsdecl, $query_string))
...
