| Atribut | Qiymat | Tavsif |
|---|---|---|
| select | expression | Majburiy. Qiymat qaysi tugun/atributdan ajratib olinishini belgilaydigan XPath ifodasi. U fayl tizimi bo‘ylab harakatlanishga o‘xshab ishlaydi: to‘g‘ri qiya chiziq (/) quyi kataloglarni tanlaydi. |
| disable-output-escaping | yes no |
Ixtiyoriy. "yes" maxsus belgilar (masalan, "<") natijaga o‘z holicha chiqarilishi kerakligini bildiradi. "no" maxsus belgilar (masalan, "<") natijaga "<" ko‘rinishida chiqarilishi kerakligini bildiradi. Standart qiymat — "no" |
