I have an xml file (SampleSyllabus.xml) with it's associated xml schema (syllabus_schema_1.3.xsd) file. I used DecisionSoft's XML schema validator to validate them. (Link: http://tools.decisionsoft.com/schemaValidate/). Both validate.
The version of SampleSyllabus.xml is shortened. But this file is basically a course syllabus represented in xml. I wanted to select some of the fields from this document, so I created a stylesheet (summary.xsl).
I am using the Eclipse EE IDE with the Xalan processor (2.7.1) to do the XSL transformation. When I go to validate the xml output (SampleOutput.xml) from this transformation... I get the error: Can not find declaration of element 'syllabus'. This error occurs just after the end of the first line in SampleOutput.xml. I used (http://www.validome.org/xml/validate/) to validate my output file.
I am new to XML/XSLT/XSD and I can't seem to figure this error out. Any help/suggestions would be very much appreciated.
I am unable to post all of the schema document. You can find the beginning of the document at the end of this post. (The full xsd document is attached as a txt file.)
