I first tried using h2pas, but found that it didn't work as well as I had hoped (perhaps a result of my inexperience in its use). As an alternative, I put together an XSLT transformation to generate the bindings from libxml2-api.xml (and its libxslt counterparts), rather than from the *.h files. This approach seems to have worked well, with the output of the transformation requiring only a tiny bit of manual editing. 

This is good to hear! Will the bindings be Kylix compatible as well?
Will it follow the namings used in Libxml2-pas? E.g. the "PxmlChar"?

By the way, we realized that mapping the memory functions to use the
Delphi memory-manager in the initialization part of the libxml2.pas
unit is not adviseable, since if using DLLs every DLLs will overwrite
the previous mapping, resulting in the function pointers being invalid
for all DLLs when the last DLL which mapped is unloaded.

I am writing now to see whether anyone else is interested this code, or in providing a "home" for it so that it can be distributed (preferably under the terms of the MIT license) to any who wish to use it. 

We are definitely interested in the code :-)

Thanks & Regards,
