I also want to auto generate code of a c++ class that could contain the data of an XML file. I tried to create one but found it very complex as the DTD can have 1. any level of nested elements and aggregates. 2. Elements and attributes can optional. 3. The OR conditions that are specified in the DTD. Is it possible we have something like a IDL compiler ? the idl compiler reads the IDL file and generates C++ classes that can be used to implement that object. Can a utility read a DTD or a schema and auto generate the code for a C++ class. This utility will be very useful, as many legacy systems do not understand the DOM tree or xml... so in order to reuse the legacy code the data from the dom tree needs to be put in a regular c++ object and fed to the legacy system and the output from a C++ object converted to xml and then sent over the web. If an effort is started to write such a utility what other complexities might arise ? regards, Abhishek. ----- Original Message ----- From: "Jean Marc VANEL" <jean-marc_vanel@e...> To: <xml-dev@i...>; <xml-dev-ig%PMDF%MHMAIL@m...>; "tcs-infra" <tcs-infra@e...>; "Madjid OUTENAH" <m_outenah@e...>; <s_durfort@m...>; <j_lolieux@m...>; <f_clerc@m...>; <thomas_moutel@e...>; <d_asseline@e...>; <guy_dauchet@e...>; "Sonia BILLINGS" <s_billings@e...> Sent: Thursday, January 20, 2000 3:12 PM Subject: XML Schema --> C++ > > > Hello > > I want to try to generate C++ class declarations from an XML Schema . > > Something like: > > <template select = '//type' > > class <value-of select="@name"/> { > <apply-templates/> > }; > </template> > > <template select = '//element' > > <value-of select="@type"/> <value-of select="@name"/> ; > </template> > > Remarks: > - not yet tested > - as writen this would generate embeded classes > - ID's and IDREF's would map to void* and list<void*> > - same principle could be applied to Java etc > - it is desirable to also generate code to fill the C++ objects using DOM or SAX API, but it seems more difficult > - it's also possible (another project!) to parse C++ declarations and generate an XML Schema ; could a round-trip be possible ? > > > > xml-dev: A list for W3C XML Developers.
