[xsd-users] Problem to transform XML to C++

[Roberto Cavalcante]

Hello everybody!


Firstly, I'd like to say I'm no XML expert and this is the first time I've
used XSD, so please be patient and forgive me in advance if I say something
senseless ;-)

I have some .XSDs files I need to convert to C++.
I've successfully configured the environment and ran the example.
However, when I tried to convert my .XSD, it complained that it cannot find
some external XSDs files; like for instance,
http://www.w3.org/2001/03/xml.xsd, among others.
So, after a look at xsd.xhtml, I've decided to download all XSDs one-by-one
because I could not identify a parameter that could allow xsd.exe to search
on web for external xsd files.
After all downloads, I used this command line:

xsd cxx-tree --location-map
http://www.w3.org/2001/03/xml.xsd=xml.xsd--location-map
http://dublincore.org/schemas/xmls/qdc/2008/02/11/dc.xsd=dc.xsd --location-map
http://www.w3.org/Math/XMLSchema/mathml2/mathml2.xsd=mathml2.xsd railML.xsd

I've got the following error message:
xsd cxx-tree --location-map
http://www.w3.org/2001/03/xml.xsd=xml.xsd--location-map
http://dublincore.org/schemas/xmls/qdc/2008/02/11/dc.xsd=dc.xsd --location-map

As you can see, the XSD target is railML.xsd.
In case you wanna reproduce the "problem" you'll can find all files here
http://www.railml.org/2010/index.php/namespace-2009.html.
Additionally, you'll need other files because as I said before, xsd.exe
seems does not have an option/command/configuration to allow
external(internet) search.
I really don't know what this error message mean and how to create this
regex.
Any help you can provide in this regard is welcome.

Thanks in advance.
