[xquery-talk] X Query NameSpace related Query

[Michael Kay]

In XQuery, if you want to find an element named
{http://www.kroger.com/JDE}thing (that is, an element whose namespace URI is
http://www.kroger.com/JDE and whose local name is "thing") then you can
either

(a) bind the default namespace to http://www.kroger.com/JDE and select it as
"thing":

declare default element namespace "http://www.kroger.com/JDE";
//thing

or (b) bind an explicit prefix to http://www.kroger.com/JDE and select it as
"pre:thing":

declare namespace pre = "http://www.kroger.com/JDE";
//pre:thing 

I assume you are aware that if your document contains
xmlns="http://www.kroger.com/JDE" in its outermost element [please don't
call it the root tag - it's not a tag and it's not the root], then all the
unprefixed elements are in this namespace.
