Within the dom extension, I am trying to resolve an issue with uris and =
local filepaths which are passed to libxml.
When I get the filepath, I need to resolve any local filepaths to an =
absoulte path. On top of this the safemode checks need to be done before =
passing any of these to libxml.

So far I started with taking the user supplied source string and running =
that through the safemode checks.
If this passes, then the source is tested as follows:

If uri, then it is passed to libxml, otherwise it gets passed through =
expand_filepath and the resolved path is passed to libxml.

It has been noted that file uris should not be passed in directly, but =
go through the same path resolutions as local files and that the =
following block of code be used instead of just using expand_filepath on =
all non uri and file uri source strings:
#ifdef VIRTUAL_DIR
    virtual_filepath_ex(source, &resolved_path, NULL TSRMLS_CC);
#else
    resolved_path =3D source;
#endif

My problem is that if VIRTUAL_DIR is not defined, then the resolved path =
ends up being the origional source supplied, which means that relative =
paths are not resolved. Also, should the path resolutions be done before =
the safemode checks?

On top of this I am looking at allowing additional registered streams to =
be used, so not sure if that would change any of this.

What is the correct way to implement this?

Thanks,

Rob
