Shelve bug in ActiveState Python? [or Python as Houdini]
I'm looking at behavior in ActiveState's Python which looks suspiciously like a bug. I've got a number of steps before I'm ready to file a real bug report (I'm a minor release behind (2.5.1.1), for one thing, so I'll need to test with the latest release, and creating a repro case for this one won't be trivial), but I'd like to do a little reality check here on the listserv before I plow ahead. Boiling the code down to its essentials, and with a few debugging output statements thrown in, what we have looks something like this: import sys, shelve, ... class ClinicalTrial: class Batch: def __init__(self, ...): self.trials = [] batches = shelve.open(batches) documentIds = assembleSomeDocumentIds(...) for docId in documentIds: clinicalTrial = ClinicalTrial(docId) if clinicalTrial.email not in batches: batch = Batch(...) else: batch = batches[clinicalTrial.email] batch.append(clinicalTrial) sys.stderr.write(about to replace batch\n) try: batches[clinicalTrial.email] = batch except Exception, e: sys.stderr.write(bailing: %s\n % e) sys.stderr.write(done replacing batch\n) The script gets through fewer than a couple dozen iterations through the loop (if it ran to completion it would be several thousand iterations), then just stops. No exception thrown, no indication whatsoever that an error has occurred, nothing. The two expected stderr messages get written for each iteration through the loop until the last time, when it writes the about to replace batch message and then just disappears into thin air. Never see the accompanying done replacing ... message, nor the bailing ... message. This can't possibly be anything but a bug in the Python engine, can it? I can't think of any other logical explanation. Just to preempt one suggestion - I do make sure I don't have any garbage laying around in the shelve file between runs (though even if I didn't do that, it surely wouldn't be acceptable for Python to just slip through a hole in the floor). -- Bob Kline http://www.rksystems.com mailto:[EMAIL PROTECTED] ___ ActivePython mailing list ActivePython@listserv.ActiveState.com To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs Other options: http://listserv.ActiveState.com/mailman/listinfo/ActivePython
Issue Attempting to Import xml.parsers.xmlproc in ActivePython
I am using python2.5 (downloaded and installed about a week ago). I am attempting to validate an XML file, using the appropriate DTD. In looking at the ASPN Cookbook, it appears that I am suppossed to use the following imports: from xml.parsers.xmlproc import xmlproc from xml.parsers.xmlproc import xmlval from xml.parsers.xmlproc import xmldtd However, when I attempt to run my python program, I get the following errors: Traceback (most recent call last): File ./feedManager.py, line 62, in module from xml.parsers.xmlproc import xmlproc ImportError: No module named xmlproc I have tried just importing xml.parsers, and that has no issue. Is there a known issue with the latest release of ActivePython and xmlproc? Thanks for any information or help that you can provide. -- Fraser MacKenzie [EMAIL PROTECTED] ___ ActivePython mailing list ActivePython@listserv.ActiveState.com To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs Other options: http://listserv.ActiveState.com/mailman/listinfo/ActivePython

You might want to look at more recent packages, such as lxml.etree [2], as it's not clear whether PyXML is still being maintained.

I am unfortunately a python novice. I know that I can use PPM to add in perl packages. How can I add modules to ActivePython.

Fraser MacKenzie wrote: I guess, a question along the same lines, is that I am trying to use the libxml2 and libxlst modules, and they don't seem to be available for ActivePython. Where can I get them to install them (or is it even possible). The reason I need them is to allow for an XML transformation using XSL. I gently suggest that you hold off on asking any further questions until you've looked more carefully at the answers you've already gotten. :-) Again, take a look at the lxml module. -- Bob Kline http://www.rksystems.com mailto:[EMAIL PROTECTED] ___ ActivePython mailing list ActivePython@listserv.ActiveState.com To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs Other options: http://listserv.ActiveState.com/mailman/listinfo/ActivePython
