Default distinct-values in Javascript

Hello,

who can I use the function 'distinct-values()' in an xPath expression with javascript? As I know this function is only available for xPath v2.0, but I could not find any option to tell javascript to use this version.

Jan

Javascript doesn't have any built-in knowledge of XPath. Calling an XPath processor is just like calling any other bit of software: you have to find a bit of software that does what you want, and then work out how to invoke it. The software that's available depends on the environment you are running in: if it's Javascript within the Internet Explorer browser (client-side) then your choices are much more limited than in some other environments.

So you need to be a bit more explicit that just saying you're running Javascript.

It's true though, there aren't very many XPath 2.0 processors around at the moment, and most of them are probably easiest to use from Java applications.
