lang( )

Synopsis

                     boolean lang(string languageCode)

The lang( ) function returns true if the context node is written in the language specified by the languageCode argument; otherwise, it is false. The nearest xml:lang attribute on the context node or one of its ancestors determines the language of any given node. If no such xml:lang attribute exists, then lang( ) returns false.

The lang( ) function takes into account country and other subcodes before making its determination. For example, lang('fr') returns true for elements whose language code is fr-FR, fr-CA, or fr. However, lang('fr-FR') is not true for elements whose language code is fr-CA or fr.
