xpath-3.1

问题 How do I use the sort function in Saxon when calling it from Java (not from XSLT). For example, for the query (data modeled on the Northwind database) I can get unsorted data using: /windward-studios/Employees/Employee But I want to get it sorted like the following (using SQL syntax here): /windward-studios/Employees/Employee order by City descending, LastName ascending How do I write the query to accomplish this?

问题 Our program displays a tree control showing the metadata structure of the XML file they are using as a datasource. So it displays all elements & attributes in use in the XML file, like this: Employees Employee FirstName LastName Orders Order OrderId For the case where the user does not pass us a XSD file, we need to walk the XML file and build up the metadata structure.

When I use the XPath 3.1 fn:serialize to round-trip the data back to JSON, the solidus characters in http:// are escaped. Is it possible to avoid this escaping when serializing back to JSON? The fn:parse-json function has an escape parameter that can be set to true() or false() , but I don't see anything similar for fn:serialize . I can
