nth-child (even) genera ParseException mentre si utilizza il selettore jsoup in Android?

Question

Eccezione:

org.jsoup.select.Selector$SelectorParseException: Could not parse query 'table:nth-child(even)': unexpected token at ':nth-child(even) 

Codice:

Document doc = Jsoup.connect(URL+params[0]).userAgent("Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.125 Safari/537.36") 
        .referrer("http://www.google.com").get(); 

Elements questions= doc.select(".content-box table:nth-child(even) a"); 

contenuti-box è un nome di classe del div.
Cosa c'è che non va nel metodo nth-child() in jsoup?

nth-child() sta funzionando nel sito http://try.jsoup.org/, ma fa un'eccezione durante l'utilizzo in Android.

Answer 1

soluzione trovata da OP:

Ora si sta lavorando, dopo che ho aggiornato il file jsuoup.jar (jsoup.org/packages/jsoup-1.8.2.jar). Credo che sia un problema con la vecchia versione.
