[xsd-users] Validation of XML files using a cached schema with xsd parser

[David White]

Thanks Boris and Stefan for your respective replies.

To clarify, I would like to be able to parse XML files using xsd C++/Parser
(via xerces-c++) without having to ship and parse an external XML schema
file.  Thus, I am hoping to hard code (or cache) the XML schema within the
source code, either as plain text or in binary form, so that XML files can
be parsed without resorting to an external XML schema file.

The reference I provided showed it is possible for C++/Tree - see the
following messages in the thread:
https://codesynthesis.com/pipermail/xsd-users/2006-September/000536.html
https://codesynthesis.com/pipermail/xsd-users/2006-September/000540.html

Is it possible for C++/Parser and if so, how?

Kind regards, David.
