Parsing Problems

[saif.shakeel]

Hi,

I have just started learning python.I need to parse an XML file
and present the contents in a particular format.The format is called
as "ini" file.I have written some code.A section of the format needs
the data to be present in format as given below:

[Services]
supported=0x10,0x1A,0x3B,0x20,0x27,0x28,0x34,0x36, 0x3E,0xA2,0xA5,0x2D,
0x22,0xA9,0x04,0xAA,0xAE

My code for this section parses the xml file and gives :
[Services]
Supported=['0x3e', '0x28', '0x3b', '0x22', '0x20', '0x27', '0xaa',
'0x10', '0xae', '0x34', '0x36', '0x2d', '0xa9', '0xa5', '0x4', '0xa2',
'0x1a']

{forget the numericals matching}.As you can see there
are single quotes around numericals ,which is not desired .I think the
problem lies in me using a list for storing and later printing out
values.I have attached few lines of code,not sure how clear it can be
to you:

for l in range(0,len(ser_par),
1):
if
ser_par[l].getAttribute('Semantics')==u'serviceId':
if
tag_exists(ser_par[l].childNodes,'VALUE'):
val =
ser_par[l].getElementsByTagName('VALUE')
value =
str(val[0].getAttribute('value'))
valu = hex(int(value))
rval.append(valu)
ser_par_num = ser_par_num + 1
prim_num = prim_num + 1

service_num = service_num + 1
variant_num = variant_num + 1
ser = list(set(rval))

print "\n[Services]"
print "Supported="+str(ser)

How can i get rid of those single quotes.

Thanking you

It's not that you store them in the list but that you simply print the
string representation of the list which does not meet your requirements.
You want to join the list elements with a comma::

print 'supported=%s' % ','.join(ser)

Hi,
Instead of using str(ser), you should create a string which combines
the individual strings in ser, separated by commas. Luckily for you,
there's a string method does just that: join.

mylist = ['0x3e', '0x28', '0x3b', '0x22', '0x20', '0x27', '0xaa',
'0x10', '0xae', '0x34', '0x36', '0x2d', '0xa9', '0xa5', '0x4', '0xa2',
'0x1a']

','.join( mylist )

This will give you:

0x3e,0x28,0x3b,0x22,0x20,0x27,0xaa,0x10,0xae,0x34, 0x36,0x2d,0xa9,0xa5,0x4,0xa2,0x1a

>>l = ['0x3e', '0x28', '0x3b', '0x22', '0x20', '0x27', '0xaa']
','.join(l)

'0x3e,0x28,0x3b,0x22,0x20,0x27,0xaa'

You may want to look at the ConfigParser package too. It's for reading/
writing .ini file.
