I'm very sorry to ask again, but I was not able to execute an XQuery file against an XML document ... I have 10.1 installed on Mc OS X. When I edit a transformation scenario, I have the options JAXP Saxon-B 9.1.0.5 Saxon-SA 9.1.0.5 Saxon6.5.5 Xalan Xsltproc As far as I understood, I should use Saxon version 9.x transformers. I use the XQuery file as "XSL URL". When I apply the scenario, I got the error: ----------------- SystemID: /Users/zastrow/Documents/ss09/xquery/second.xquery Programmname: Saxon6.5.5 Feherlevel: error Beschreibung: Failed to parse stylesheet SystemID: /Users/zastrow/Documents/ss09/xquery/second.xquery Programmname: Saxon6.5.5 Feherlevel: fatal Beschreibung: Content is not allowed in prolog. Anfang: 1:1 ------------------ I'm quite sure that I'm doing something wrong ..?
