Need a Regular expression to remove a char for Unicode text

2006-10-13 Thread శ్రీనివాస 
Hai friends,
Can any one tell me how can i remove a character from a unocode text.
కల్‌హార is a Telugu word in Unicode. Here i want to
remove '' but not replace with a zero width char. And one more thing,
if any whitespaces are there before and after '' char, the text should
be kept as it is. Please tell me how can i workout this with regular
expressions.

Thanks and regards
Srinivasa Raju Datla

Don't know anything about Telugu, but is this the approach you want?

 x=u'\xfe\xff  \xfe\xff \xfe\xff\xfe\xff'
 noampre = re.compile('(?!\s)(?!\s)', re.UNICODE).sub
 noampre('', x)
u'\xfe\xff  \xfe\xff \xfe\xff\xfe\xff'

The regular expression has negative look behind and look ahead
assertions to check that there is no whitespace surrounding the ''
character. Each match then found is then  replaced with the empty string

So basically, you want to match 200c and replace it with 200c,
but only if it's not surrounded by whitespace, right?

r(?!\s)\x200c(?!\s) should match. I'm sure you'll be able to take
it from there.

He wants to replace  with zero width joiner so the last call should be
noampre(u\u200D, x)

Pardon my poor reading comprehension, OP doesn't want zero width
joiner. Though I'm confused why he mentioned it at all.
