[xsd-users] xsd:any in parser

[Jiri Poledna]

   Hi Boris
   This is what I expect, override some methods, my problem is that I
   have nothing to override, when I run xsd.exe it do not generate that
   "any" methods to override. Do you think I need switch on some
   attribute in generation process to obtain such methods? I'm using "xsd
   cxx-parser --morph-anonymous book.xsd"
   Thanks

   I'm using xsd.exe utility to generate the hxx and txx, I obtained
   parserhooks to Title element, but I do not reach Reviewer element.


The hooks you are interested in are:

virtual void
_start_any_element (const xml_schema::ro_string& ns,
                    const xml_schema::ro_string& name);

virtual void
_end_any_element (const xml_schema::ro_string& ns,
                  const xml_schema::ro_string& name);

virtual void
_any_attribute (const xml_schema::ro_string& ns,
                const xml_schema::ro_string& name,
                const xml_schema::ro_string& value);

virtual void
_any_characters (const xml_schema::ro_string&);


They pretty much constitute SAX events and are triggered for elements,
attributes, and text of wildcard/mixed content. In your case, you will
need to override them in the implementation of the Title parser. The
Reviewer element (in place of an any) and all its nested contents will
be delivered via these hooks.
