Hi, c.l.p.'ers-
I am having a problem with the import of xml.parsers.expat that has
gotten me completely stumped. I have two programs, one a PyQt program
and one a command line (text) program that both eventually call the
same code that imports xml.parsers.expat. Both give me different
results...
Sorry, that should have been "xml.parsers.expat"
