Re: Relative paths in C++ on Macintosh OS X

[James Berry]

Steve,
Could you do a bit of debugging on this?
One way or another, the relative path should be resolved inside 
XMLParsePathToFSRef_X in MacOSPlatformUtils.cpp. This would be either 
in response to getCurrentDirectory (which calls XMLParsePathToFSSpec 
with the path "."), or with the entire relative path. In this case, 
XMLParsePathToFSRef_X calls getcwd to retrieve the current directory, 
then prepends it to the path, followed by a "/".

I firmly believe (until proven otherwise) that getcwd is returning "/" 
in your case, perhaps because that's what the cwd is set to??? Can you 
set a breakpoint, or add some debug output, to verify this condition?

I'm using xcode (1.5) with the default gcc 3.3 and OS (10.3.8) and 
the latest xerces (2.6 I believe, this behavior was the same for 
other recent releases).

We're initializing the parser with:
    xercesc::XMLPlatformUtils::Initialize();
    mParser.reset( new xercesc::XercesDOMParser() );
    mParser->setValidationScheme( 
xercesc::XercesDOMParser::Val_Always );
    mParser->setDoNamespaces( false );
    mParser->setDoSchema( true );
    mParser->setCreateCommentNodes( false ); // No comment nodes
    mParser->setIncludeIgnorableWhitespace( false ); // No text nodes

    mErrHandler.reset( (xercesc::ErrorHandler*)new 
xercesc::HandlerBase() );
    mParser->setErrorHandler( mErrHandler.get() );

And passing the file string to
     parser->parse( xmlFile.c_str() );
where parse is a pointer to the already initialized parser.
If I pass in
    ../../../configuration.xml
The parser looks for the file configuration.xml in the root 
directory. If its not there
then I get an exception message of

    The primary document entity could not be opened. 
Id=//../../../configuration.xml

Note the extra "/"'s in front of the string that I passed in.
Thanks for your help.
Steve

Steve,
I don't know of a problem in this area. I've used relative paths
successfully. But your setup may be somewhat different.
Can you provide more information about the context in which  you're
seeing this issue? Build environment? Compiler? What API you're 
passing
the relative path to? Can you duplicate the issue with a test program?

I'm having difficulty getting the Xerces-C++ parser to use relative
paths on Mac OS X. Using absolute paths works fine.
But when I try to pass the parser a path such as
    ../../../configuration.xml
Note that it's puzzling why the path above gets converted into an
absolute path as below... It looks like the current directory is root.
Xerces should be calling getcwd to fetch the current directory (and
does so at XMLParsePathToFSRef_X in MacOSPlatformUtils.cpp.

I get an error:
The primary document entity could not be opened.
Id=//../../../configuration.xml
Do I need to use the routines in MacOSPlatformUtils.hpp to help with
this somehow?
Any help on this would be appreciated.
Thanks,
Steve
