php - How to preg_match_all() + extract + replace + delete? -

-

i'm not experienced preg_match_all , similar , looking simple way following:

consider text:

$string = 'this text written on [set_stamp]1341066037[/set_stamp] , 1 on [set_stamp]1340903119[/set_stamp].';

what need do:

  1. get data (here timestamps) between tags [set_stamp] , [/set_stamp]
  2. replace captured timestamps corresponding date like: date('y-m-d h:i:s', $timestamp)
  3. remove [set_stamp] , [/set_stamp] tags

the final output similar this:

"this text written on 2012-07-12 14:26 , 1 on 2012-07-11 17:10."

you can use preg_replace_callback() following regex:

#\[set_stamp\](.+)\[/set_stamp\]#iu

example code:

$string = 'this text written on [set_stamp]1341066037[/set_stamp] , 1 on [set_stamp]1340903119[/set_stamp].'; echo preg_replace_callback('#\[set_stamp\](.+)\[/set_stamp\]#iu', function($m) {     return date('y-m-d h:i', $m[1]); }, $string);

the output of code is:

this text written on 2012-06-30 16:20 , 1 on 2012-06-28 19:05.

note anonymous function requires @ least php 5.3. if using old version , can't update, create normal function , pass name string.

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...
