i displaying blog rss feeds in website , 1 of blog soooo big 2-3 lines of description should display in website how can that? please me in advance

am using magpierss-0.72 fetch rss code is

require_once('rss_fetch.inc');  $url = 'http://rajs-creativeguys.blogspot.com/feeds/posts/default?alt=rss';  $rss = fetch_rss($url);  foreach ($rss->items $i => $item ) {      $title = strtoupper ($item['title']);     $url   = $item['link'];     $desc = $item['description'];     $date = $item['pubdate'];      echo "<div class=\"blog\"><a target=\"_blank\" href=$url><h1>$title</h1>$desc<br/><br/><em>dated : $date <br/><br/></em></a></div> "; }

and blog address http://rajs-creativeguys.blogspot.in/

 $desc = substr(0,150,$item['description']);

to first 150 characters.

if want 150 words use

$desc = ''; $max = 150; $arr = explode(' ', strip_tags($item['description'])); $l = count($arr); if($l < $max) $max = $l; for($i=0;$i<$max;++$i)     {     $desc .= $arr[$i] . ' ';     }

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...
