Good question. For some reason MailScanner decided your message
had a high probability of being spam. Fortunately Mail.app wasn't
quite so easily fooled...
Ah. BTW, your question made me realize that I wanted to print error
names too, so I ended up implementing the scheme I suggested before,
using SWIG instead of GCC-XML. In case anyone is interested, the
process goes like this:
swig -xml -module errors -o NSXMLParser.xml /System/Library/
Frameworks/Foundation.framework/Versions/C/Headers/NSXMLParser.h
xsltproc enum.xsl NSXMLParser.xml | xmllint --format - > errors.plist
using the stylesheet below. SWIG does not grok Objective-C method
declarations, but it's ok since it keeps parsing the file anyway. The
result is a plist containing all enums in the file as dictionaries.
Filtering and support for #defines can be easily added.
