Re: How to check node is existed or not in xforms

Hi,

Will the XPath 2.0 function exist() work in your instance?

Along with the if construct

"if ( exists( instance('mine')/xpath/to/it ) ) then ... else ()"

not sure if you need a string, boolean or node to be returned, or

an empty sequence, () .

Regards,

Hank
