The Java-based XQL processor and the native XML processor both implement query languages and return documents in parsed form, but they use different functions and methods.
The native XML processor implements XML query language. It provides a built-in function, xmlparse, that returns, in parsed form, a document suitable for efficient processing with the xmlextract and xmltext built-in functions.
The Java-based XQL processor is an earlier facility that implements the XQL query language. It provides a Java method, com.sybase.xml.xql.Xql.parse, that returns a parsed form of a document that is a sybase.aseutils.SybXmlStream object, suitable for processing with the com.sybase.xml.xql.Xql.query method.
If you want to migrate documents between the Java-based XQL processor and the native XML processor, you should be aware of the following possibilities and restrictions:
Documents in text form can be processed directly by both the Java-based XQL processor and the native XML processor.
The sybase.aseutils.SybXmlStream documents generated by com.sybase.xml.xql.Xql.parse can only be processed by the Java-based XQL processor. They cannot be processed by the built-in functions xmlextract or xmltest.
The parsed documents generated by the xmlparse built-in function can only be processed by the xmlextract and xmltest built-in functions. They cannot be processed by the Java-based XQL processor.
