OT: ja sice chapu, ze na XML/HTML je potreba pouzivat zasobnikovy automat, ale IMHO existuje trivialni subset uloh, na ktery staci i regexpy... Samozrejme je potreba vedet co chci, a jaky to ma pripadne limity, ale nutne bych netvrdil, ze dostat subset dat z validniho XML/HTML umi jen nas vsemocny oblibenec :D<br>

Potřebuji pomoc s pythonním re modulem. Hraji si s tím už několik hodin<br>
