Hi!
I want to replace some seqs. in a html.
Let:
a-
b
= ab
but:
xxx -
b
must be unchanged, because it is not word split.
I want to search and replace with re, but I don't know how to neg. this
set ['\ \n\t'].
This time I use full set without these chars, but neg. is better and
shorter.
Ok, I can use [^\s], but I want to know, how to neg. set of chars.
sNorm1= '([^[\ \t\n]]{1})\-\<br\ \/\>\n' - this is not working.
Thanks for the help:
dd
sNorm1= '([%s]{1})\-\<br\ \/\>\n'
c = range(0, 256)
c.remove(32)
c.remove(13)
c.remove(10)
c.remove(9)
s = ["\\%s" % (hex(v).replace('00x', '')) for v in c]
sNorm1 = sNorm1 % ("".join(s))
print sNorm1
def Normalize(Text):
rx = re.compile(sNorm1)
def replacer(match):
return match.group(1)
return rx.sub(replacer, Text)
print Normalize('a -<br />\nb')
print Normalize('a-<br />\nb')
sys.exit()
It looks like you are trying to de-hyphenate words that have been
broken across line breaks.
Well, this isn't a regexp solution, it uses pyparsing instead. But
I've added a number of other test cases which may be problematic for an
re.

from pyparsing import makeHTMLTags,Literal,Word,alphas,Suppress
brTag,brEndTag = makeHTMLTags("br")
hyphen = Literal("-")
hyphen.leaveWhitespace() # don't skip whitespace before matching this
collapse = Word(alphas) + Suppress(hyphen) + Suppress(brTag) \
+ Word(alphas)
# define action to replace expression with the word before hyphen
# concatenated with the word after the <BRtag
collapse.setParseAction(lambda toks: toks[0]+toks[1])
print collapse.transformString('a -<br />\nb')
print collapse.transformString('a-<br />\nb')
print collapse.transformString('a-<br/>\nb')
print collapse.transformString('a-<br>\nb')
print collapse.transformString('a- <BR clear=all>\nb')
