  1. „ modernes XML im praktischen Einsatz “ - Schnittstellen und Integrationsmöglichkeiten von XMLauf Basis von Konvertierungsproblemen

  2. Gliederung • XML (Rec 1.0) • DTD - Document Type Definition (Rec 1.0) • XSLT (Rec 1.0) • XSLT - Integration • XSLT - Prozeß • XML - Szenario[1] extern • XML - Szenario[2] intern • Tech. Anforderungen - Konvertierung • XSL Prozessoren • WEB Seiten • XML / XSL Tools
