What I am looking for is an XPath expression, suitable for sticking in the string() function, to get the most preferred non-null element. In XPath 1.0: title[lang($preferredLanguage)] | title[lang($2ndPreferredLanguage)][not(title[lang($preferredLanguage)])] This returns the union set of titles with the preferred language and titles with the second preferred language when there are no titles of the preferred language. (You could take the first of this set if you wanted to be sure you'd never have more than one of whichever of these you had.) In XPath 2.0: (title[lang($preferredLanguage)], title[lang($2ndPreferredLanguage)])[1] This returns the first of the sequence of titles with the preferred language followed by titles with the second preferred langage.
