[Tutor] xml parsing from xml
Hi I just want to create a new xm file from existing xml file. so basically i want to put contry details in countryName.xml from these file. I thought to do via read a line by line with normal file handling. but there a problem with that. So i want to handle python XML . Could you please suggest on this. Any Idea is welcome Thanks regards Jitendra ?xml version=1.0?data country name=Liechtenstein rank updated=yes2/rank year2008/year gdppc141100/gdppc neighbor name=Austria direction=E/ neighbor name=Switzerland direction=W/ /country country name=Singapore rank updated=yes5/rank year2011/year gdppc59900/gdppc neighbor name=Malaysia direction=N/ /country country name=Panama rank updated=yes69/rank year2011/year gdppc13600/gdppc neighbor name=Costa Rica direction=W/ neighbor name=Colombia direction=E/ /country/data ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] xml parsing from xml
@All thanks, I cant use etree/SAX because there we cant get complete line , of course we can get it by tag name but we are not sure about tag also. Only we know what ever child of country we need to put in new file with country name. Note: File size is around 800MB, for other requirement(Like converting xml to csv) i used lxml/others. but in my current scenario i dont know what child tag will be there . ## INPUT XML ### ?xml version=1.0? data country name=Liechtenstein rank updated=yes2/rank year2008/year gdppc141100/gdppc neighbor name=Austria direction=E/ neighbor name=Switzerland direction=W/ ... ... /country country name=Panama rank updated=yes69/rank year2011/year gdppc13600/gdppc neighbor name=Costa Rica direction=W/ neighbor name=Colombia direction=E/ /country /data outputxml (Liechtenstein.xml) ## ?xml version=1.0? data country name=Liechtenstein rank updated=yes2/rank year2008/year gdppc141100/gdppc neighbor name=Austria direction=E/ neighbor name=Switzerland direction=W/ ... ... /country /data # # ?xml version=1.0? data country name=Panama rank updated=yes69/rank year2011/year gdppc13600/gdppc neighbor name=Costa Rica direction=W/ neighbor name=Colombia direction=E/ /country /data On Thu, May 8, 2014 at 1:19 AM, Stefan Behnel stefan...@behnel.de wrote: Neil D.

The documenation gives examples of both. sax is easiest and fastest for simple XML in big files ... I wouldn't say that SAX qualifies as easiest. Sure, if the task is something like count number of abc tags or find tag xyz and get an attribute value from it, then SAX is relatively easy and also quite fast. That's pretty much what I said. simple task, big file. sax is easy. For anything else use etree. BTW, ElementTree also has a SAX-like parsing mode, but comes with a simpler interface and saner parser configuration defaults. My experience was different. Etree is powerful but for simple tasks I just found sax easier to grok. (And most of my XML parsing is limited to simple extraction of a field or two.) If I understand this task correctly it seems like a good application for SAX. As a state machine it could have a mere two states, assuming we aren't troubled about the parent nodes of Country tags. Yep, that's the kind of thing I meant. You get started, just trying to get out one little field out of the file, then notice that you need another one, and eventually end up writing a page full of code where a couple of lines would have done the job. Even just safely and correctly getting the text content of an element is surprisingly non-trivial in SAX. It's still unclear what the OP wanted exactly, though. To me, it read more like the task was to copy some content over from one XML file to another, in which case doing it in ET is just trivial thanks to the tree API, but SAX requires you to reconstruct the XML brick by brick here. In my own personal case, I partly prefer xml.sax simply because it ignores namespaces, a nice benefit in my cases. I wish I could make ElementTree do that. The downside of namespace unaware parsing is that you never know what you get. It works for some input, but it may also just fail arbitrarily, for equally valid input. One cool thing about ET is that it makes namespace aware processing easy by using fully qualified tag names (one string says it all). Most other XML tools (including SAX) require some annoying prefix mapping setup that you have to carry around in order to tell the processor that you are really talking about the thing that it's showing to you.

[Tutor] Unit test case
Hi, I am working one tool, which will do compile/run the workspace (that code is written on c/c++). on that my requirment is i need to compile subfolder also, i have wrote code for that also. My problem is , i am unable to write the Unit test case for that. Since my method (called run_subfolder) is not retrurning any thing (this will create one command line argument in that i am adding subfolder condition and passing to the another class which will do actual thing) . For this method i need to write unit test case. Since i dont have to workspace also , so that i can test this case . Please advise on this. what i need to do. this is possible or not, if not why. Some forum suggested use mox. but i dont have more idea on this . in mox how i will get thet output of the function Thanks Jitendra Kumar ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] confusing enumerate behavior

Hi Tutors,
I'm a little, actually a lot confused by the behavior of the enumerate
function here. I have a text and I want to get each word within the context
of the three preceding and the three following words. I tried this:
#BEGIN
my_input = one two three four five six seven eight nine ten
text = my_input.split()
for i,v in enumerate(text):
line = text[i-3], text[i-2], text[i-1], v, text[i+1], text[i+2],
text[i+3]
print line
# END
The ouput was not as I expected. It did not start from the beginning
(actually I had expected it to throw and exception immediately)
('eight', 'nine', 'ten', 'one', 'two', 'three', 'four')
('nine', 'ten', 'one', 'two', 'three', 'four', 'five')
('ten', 'one', 'two', 'three', 'four', 'five', 'six')
('one', 'two', 'three', 'four', 'five', 'six', 'seven')
('two', 'three', 'four', 'five', 'six', 'seven', 'eight')
('three', 'four', 'five', 'six', 'seven', 'eight', 'nine')
('four', 'five', 'six', 'seven', 'eight', 'nine', 'ten')
Traceback (most recent call last):
File enumerate.py, line 13, in module
line = text[i-3], text[i-2], text[i-1], v, text[i+1], text[i+2],
text[i+3]
IndexError: list index out of range
e...@emad-laptop:~/Desktop$
I then though of adding dummy words to the beginning and the end and exclude
them later like this:
#BEGIN
my_input = one two three four five six seven eight nine ten
text2 = nothing *6 + my_input + nothing * 6
text2 = text2.split()
for i,v in enumerate(text2[6:-6]):
line = text2[i-3], text2[i-2], text2[i-1], v, text2[i+1], text2[i+2],
text2[i+3]
print line
#END
The output this time was even more confusing:
e...@emad-laptop:~/Desktop$ python enumerate.py
('nothing', 'nothing', 'nothing', 'one', 'nothing', 'nothing', 'nothing')
('nothing', 'nothing', 'nothing', 'two', 'nothing', 'nothing', 'nothing')
('nothing', 'nothing', 'nothing', 'three', 'nothing', 'nothing', 'nothing')
('nothing', 'nothing', 'nothing', 'four', 'nothing', 'nothing', 'one')
('nothing', 'nothing', 'nothing', 'five', 'nothing', 'one', 'two')
('nothing', 'nothing', 'nothing', 'six', 'one', 'two', 'three')
('nothing', 'nothing', 'nothing', 'seven', 'two', 'three', 'four')
('nothing', 'nothing', 'one', 'eight', 'three', 'four', 'five')
('nothing', 'one', 'two', 'nine', 'four', 'five', 'six')
('one', 'two', 'three', 'ten', 'five', 'six', 'seven')
Can somebody please explain what is going on here? Have I done something
wrong? How can this be fixed?
