Jekk ħtieġa tiegħek huwa li jaqsam node valur fi XML, li fih sensiela delimitata ta 'valur, fil-punti individwali, imbagħad inti lħaqt l-post dritt ... agħti ħarsa lejn l-eżempju hawn taħt. Jekk inti familjari ma 'ftit ta' XML u XSL ... ma naħsibx li għandek bżonn xi spjegazzjoni.
Ukoll, dan l-eżempju tinkludi l-użu tal-funzjonijiet XSL bħal XSL: sejħa mudell, XSL: substring-qabel, XSL: substring-wara, jekk dan huwa dak li inti wara.
