PHP access array within simpleXML -

-

i have soap request returning array of ids. reason, having trouble accessing array within simplexml element.

i did vardump of simplexml object:

die(var_dump($polist)); object(simplexmlelement)#7 (1) { ["int"]=> array(10) { [0]=> string(5) "20622" [1]=> string(5) "20868" [2]=> string(5) "20880" [3]=> string(5) "20883" [4]=> string(5) "21034" [5]=> string(5) "21065" [6]=> string(5) "21136" [7]=> string(5) "21160" [8]=> string(5) "21202" [9]=> string(5) "21247" } }

and var dump of though array:

die(var_dump($polist->int)); object(simplexmlelement)#8 (1) { [0]=> string(5) "20622" }

how access array?

simplexmlelement implements traversable, should able do:

foreach( $polist->int $el)     echo $el;

or possibly query array xpath:

$array = $polist->xpath( '/int')[0]; foreach( $array $el)     echo $el;

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...
