newbe question about removing items from one file to another file

I am pretty sure my code isn't close to what I want. I need to be able
to skip html like commands from <definedto <undefinedand to key on
another word in adition to </CsInstrumentsto end the routine

I was also looking at se 2.2 beta but didn't see any easy way to use it
for this or for that matter search and replace where I could just add
it as a menu item and not worry about it.

Dexter,

Here's a function that screens out all instrument blocks and puts them into a dictionary keyed on the instrument number:

--------------------------------------------

def get_instruments (file_name):

INSIDE = 1
OUTSIDE = 0

f = file (file_name, 'ra')
state = OUTSIDE
instruments = {}
instrument_segm ent = ''

for line in f:
if state == OUTSIDE:
if line.startswith ('<CsInstrument s'):
state = INSIDE
instrument_segm ent += line
else:
instrument_segm ent += line
if line.lstrip ().startswith ('instr'):
instrument_numb er = line.split () [1]
elif line.startswith ('</CsInstruments') :
instruments [instrument_numb er] = instrument_segm ent
instrument_segm ent = ''
state = OUTSIDE

f.close ()
return instruments

------------------------------------------------

You have received good advice on using parsers: "beautiful soup" or "pyparse". These are powerful tools capable of doing complicated
extractions. Yours is not a complicated extraction. Simon tried it with "beautiful soup". That seems simple enough, though he finds
the data by index leaving open where he gets the index from. There's surely a way to get the data by name.
Contrary to the parser the function will miss if tags take liberties with upper-lower case letters as they are probably
allowed by the specification. A regular expression might have to be used, if they do.
From your description I haven't been able to infer what the final format of your data is supposed to be. So I cannot tell you
how to go on from here. You'll find out. If not, just keep asking.

The SE solution which you said couldn't work out would be the following. It makes the same dictionary the function makes and it is
case-insensitive:

------------------------------------------------

>>Instrument_Se gment_Filter = SE.SE ('<EAT"~(?i)<Cs Instruments>(.| \n)*?</CsInstruments>~ ==\n\n" ')
instrument_se gments= Instrument_Segm ent_Filter ('file_name', '')
print instrument_segm ents

(... see all instrument segments ...)

>>Instrument_Nu mber = SE.SE ('<EAT~instr.*~ ==\n')
instruments ={}
for segment in instrument_segm ents.split ('\n\n'):

if segment:
instr_line = Instrument_Numb er (segment)
instrument_numb er = instr_line.spli t ()[1]
instruments [instrument_numb er] = segment

--------------------------------------------------

(If you're on Windows and the CRs bother you, take them out with an additional definition when you make your
Instrument_Bloc k_Filter: (13)= or "\r=")

Thanks for the help I can't wait to try it out.. (has to wait for the

If I understand correctly you want to write the instruments block to a file (from <CsInstrumentst o </CsInstruments>) ? Right? Or
each block to its own file in case there are several?. You want your code to generate the file names? Can you confirm this or
explain it differently?

sorry about that this is a link to a discription of the format
http://kevindumpscore.com/docs/csoun...ndunifile.html
It is possible to have more than one instr defined in an .csd file so I
would need to look for that string also if I want to seperate the
instruments out.

http://www.dexrow.com

--
http://mail.python.org/mailman/listinfo/python-list

I need to take it between the blocks only I also need to make sure I
only take one instrument
defined in this example with the code instr 1 I also need the code

<CsInstrument s>

; originally tone.orc
sr = 44100
kr = 4410
ksmps = 10
nchnls = 1

regardless of what instrument I take. The function would have to
except the instrument number as an argument

http://www.dexrow.com

Using BeautifulSoup and the interactive interpreter, I figured out the
following script in about 15 minutes:

# s is a string containing the example file from above.

from BeautifulSoup import BeautifulStoneS oup

soup = BeautifulStoneS oup(s)
csin = soup.contents[0].contents[5]
lines = csin.string.spl itlines()

print csin.string

It prints:

; originally tone.orc
sr = 44100
kr = 4410
ksmps = 10
nchnls = 1
instr 1
a1 oscil p4, p5, 1 ; simple oscillator
out a1
endin
and of course you could say "lines = csin.string.spl itlines()" to get a
list of the lines. That doesn't take you all the way, but it's
something.

Hope that helps,
Peace,
~Simon

I seem to be having problems getting the code to work.. Seems to crash
my whole project, I don't know if I am missing an import file or what
(I had to go back to an older version on my hd.. I have uploaded what
I have on to sourceforge

https://sourceforge.net/project/show...ease_id=444362

thanks for the help

This thread seems to have split. So let me reiterate: please copy the output when you cut, paste and run. If you have an
import problem it must be on the other side of your interface with SE, because I don't import anything and SE imports what it needs.

I am have to be able to distribute se with the project in order to use
it
I started with import se but I did not use the setup command
when I comment out import se the program works and when
I use import se everything connected to the library crashes on the
import line..

You don't need the setup command. Just place SE.py and SEL.py into a path where the import can find it. Also make sure SE.py and
SEL.py are spelled exactly like this. Linux requires the extension to be lower case, as I was myself made aware of by an alert
person who was also experiencing import problems. I must confess that my fist uploads were upper case (SE.PY). I instantaneously
replaced the upload with corrected spelling and apologize for the trouble the mistake may be causing. Fortunately correcting it is a
small matter.
Have you tried to run the function at all? It produces the same result. Made case-insensitive (if need be) I'd prefer the
function. It is more economical, since it doesn't require an extra import. It surely runs faster too (if that matters).
