Delete some informations in a json variable with php -

-

my problem parsing xml file , file contain information don't want exporting json data. in case want function return json data first '[' caratere php code:

    <?php  class xmltojsonconverter {     public function parsexml ($url) {         $filecontents= file_get_contents($url);         // remove tabs, newline, whitespaces in content array         $filecontents = str_replace(array("\n", "\r", "\t"), '', $filecontents);         $filecontents = trim(str_replace('"', "'", $filecontents));         $myxml = simplexml_load_string($filecontents);         $json = json_encode($myxml);         return $json;     } } //path of xml file $url= 'http://www.lequipe.fr/rss/actu_rss_football.xml';  //create object of class $jsonobj = new xmltojsonconverter();  //pass xml document class function $myjson = $jsonobj->parsexml($url); print_r ($myjson); ?>

this part of json result :

{"@attributes":{"version":"2.0"},"channel":{"title":"l'equipe.fr actu football","link":"http://www.lequipe.fr","description":"l'equipe.fr, toute l'actualit\u00e9 du football","language":"fr","copyright":"copyright l'equipe.fr","pubdate":"wed, 22 apr 2015 16:31:08 +0200","image":{"url":"http://www.lequipe.fr/rss/logo_rss.gif","title":"l'equipe.fr","link":"http://www.lequipe.fr","width":"119","height":"28"},"item":[{"title":"foot - cha

i want result start '['

thank you

remove every attribute don't want before encoding json:

public function parsexml ($url) {     $filecontents= file_get_contents($url);     // remove tabs, newline, whitespaces in content array     $filecontents = str_replace(array("\n", "\r", "\t"), '', $filecontents);     $filecontents = trim(str_replace('"', "'", $filecontents));     $myxml = simplexml_load_string($filecontents);     //--------------     unset($myxml['@attributes']);     unset($myxml['channel']);     unset($myxml['image']);     //--------------     $json = json_encode($myxml);     return $json; }

or if need item:

public function parsexml ($url) {     $filecontents= file_get_contents($url);     // remove tabs, newline, whitespaces in content array     $filecontents = str_replace(array("\n", "\r", "\t"), '', $filecontents);     $filecontents = trim(str_replace('"', "'", $filecontents));     $myxml = simplexml_load_string($filecontents);     //--------------     $json = json_encode($myxml['item']);     return $json; }

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
