[xsd-users] Question about code synthesis C++/Tree : serialization and XSD patterns

[LA FATA, Anael]

Hi and thank you very much for your answer.

If I understand you well, I have no other solution that redefining << operators for each type that has a specific pattern ?
There is no "generic" solution that could work for any XSD file (since I have several XSD and they might change in the future) ?

Regex patterns are only used for validation. It is generally impossible to take a pattern and produce output that matches it except by doing an exhaustive search.

However, the cxx/tree/custom/double/ example in the XSD distribution shows another way to achieve what you want.
