Now I've an error my asp.net page The literal string "1Apparato gastrointestinale e metabolismo361Antiacidi .... .................was found. Literal strings are not allowed within this control. If I display the writer, I don't see the structure of the xslt, but all the fields without structure. es. 1Apparato gastrointestinale e metabolismo361Antiacidi e antiulcera371Antispastici381Procinetici391Antiemetici e antinausea401 I think the correct structure is Apparato gastrointestinale e metabolismo361Antiacidi ecc..
