Order By in XPath

Hi all,

Is there a standard way to order the results of an XPath query.
In SQL you would use order by, but does XPath have an equivelant?

no, strict XPath doesn't. but JSR 170 specifies an extension to standard XPath 
which is borrowed from XQuery.

See spec section 6.6.5.5

Example:

//element(*, car)[@colour='green'] order by @price ascending
