python - improve robots regular expression -

-

i have made following regexp extracting robots links:

re.compile(r"/\s+(?:\/+)")

and following result:

/includes/ /modules/ /search/ /?q=user/password/ /?q=user/register/ /node/add/ /logout/ /?q=admin/ /themes/ /?q=node/add/ /admin/ /?q=comment/reply/ /misc/ //example.com/ //example.com/site/ /profiles/ //www.robotstxt.org/wc/ /?q=search/ /user/password/ /?q=logout/ /comment/reply/ /?q=filter/tips/ /?q=user/login/ /user/register/ /user/login/ /scripts/ /filter/tips/ //www.sxw.org.uk/computing/robots/

how can exclude links has 2 slashes like:

 //www.sxw.org.uk/computing/robots/  //www.robotstxt.org/wc/  //example.com/  //example.com/site/

any ideas ??

i'll suggest add if condition:

 if not line.startswith(r'//'):      #then here

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
