[xsd-users] cxx-parser with --file-per-type

[Latrach, Farhat]

Hi Boris,

Thanks for your prompt answers.

For my case, the cxx-tree does not fit well my need as I still need to parse the whole tree and for such amount of objects it will be very complicated. I would prefer parse directly with xercess instead. Please let me know if I am wrong.

The pattern of the error is when I run xsd cxx-parser -file-per-type --generate-validation the xsd starts generating some files and suddenly ends with "runtime error".
I removed the --generate-validation (I have changed to use xercess instead of expat) the error disappeared and a big chunk of files are generated. It works fine. I guess there is something wrong when using both --file-per-type and --generate-validation.

The test driver file I got does contain only the root element in the my_schema.xsd I am compiling. But, The xml I am expecting to parse has the root element of the included schema:( 

So, I did generate a test driver for the included schema as well and I have tried modifying one of its generated parsers by adding to it my_schema_test_drive root parser (a way to include my schema parsers  in the root parser of the included schema which is the root for the xml); by modifying its constructor and _start/end_element methods.
 
It worked fine and now I can parse all the included schemas elements and the root element of my schema (and its sub elements) in the xml file. 

The problem is: I have many other included schemas in my root element for which I need to make the same way of linking and obviously I need to automate this. 

My questions:
Is there a better way (or other compiling options) to generate a test driver taking into account automatically the root elements of included schemas (putting --root-element my_included_schema_root_element does not work)? 

I would like to use the test driver as it generates automatically what I need and I would only change the .impl.cxx files for my implementations.

PS: Please don't ask me to change the .xsd files as I am not in a position to change them.

Thanks a lot!

Thanks, I am glad you like it.

I can't say for sure what it wrong without knowing exactly what error you are getting. Having said that, the C++/Parser mapping is meant for simple schemas since you will have to implement a parser for every type yourself. For complex schemas I would recommend you use C++/Tree instead.

No. Also, this option won't help you with your issue (complex import/include graphs).
