How does this compare to using a Python function such as filter. Re: xmltodict - not understanding how to make it fully useful 9 Years Ago by Gribouillis > How does this compare to using a Python function such as filter. Can you be more specific ? The role of `filter()` is to select a subsequence in a sequence. It is a different problem. Re: xmltodict - not understanding how to make it fully useful 9 Years Ago by flebber No it is different I was trying to use filter after I posted this last night and saw your post use. a = gather(xml_doc, (('meeting', '@id'), ('meeting', '@venue'))) and thought if that was a function(which is what you created). Don't worry just because it was the last thing I did late lst night. def gather(a): a = gather… Re: xmltodict - not understanding how to make it fully useful 9 Years Ago by Gribouillis In this case, the decorator transform a function which generate values into a function which returns a list of these values. Without the decorator, I would write def gather(xml_doc, paths): result = [] for p in paths: node = xml_doc for word in p: node = getitem(node, word) … Re: xmltodict - not understanding how to make it fully useful 9 Years Ago by Gribouillis Sorry I meant @post_process(list) def gather(xml_doc, paths): for p in paths: node = xml_doc for word in p: node = node[word] yield node `getitem()` exists, but it is in module `operator`. You must also import `post_process()` from another file. For example, store it in a module … Re: xmltodict - not understanding how to make it fully useful 9 Years Ago by flebber Do I need to write anything in post_process.py?
