You haven't told us what you expect it to do. In any case, your subject heading indicates that the problem is 99.999% likely to be in your logic -- the converse would require the result of re.compile() to retain some memory of what it's seen before *AND* to act differently depending somehow on those memorised facts. > > I'm writing my own cheesy config.ini parser because ConfigParser > doesn't preserve case or order of sections, or order of options w/in > sections. > > What's confusing me is this: > If I try matching every line to one pattern at a time, all the > patterns that are supposed to match, actually match. > If I try to match every pattern to one line at a time, only one > pattern will match. > > What am I not understanding about re.search? Its behaviour is not contingent on previous input. The following pseudocode is not very useful; the corrections I have made below can be made only after reading the actual pastebin code :- ( ... you are using the name "pattern" to refer both to a pattern name (e.g. 'setting') and to a compiled regex. > Doesn't match properly: > <code> > # Iterate through each pattern for each line > for line in lines: > for pattern in patterns: you mean: for pattern_name in pattern_names: > # Match each pattern to the current line > match = patterns[pattern].search(line) you mean: match = compiled_regexes[pattern_name].search(line) > if match: > "%s: %s" % (pattern, str(match.groups()) ) you mean: print pattern_name, match.groups > </code> > > _Does_ match properly: > <code> [snip] > </code> > > Related code: > The whole src http://pastebin.com/f63298772 This can't be the code that you ran, because it won't even compile. See comments in my update at http://pastebin.com/m77f0617a By the way, you should be either (a) using *match* (not search) with a \Z at the end of each pattern or (b) checking that there is not extraneous guff at the end of the line ... otherwise a line like "[blah] waffle" would be classified as a "section".
