php - How to get xml node value by attribute value with simplexml? -


i've got xml generated external service looking this:

<data>     <eventlist>         <events>             <event id="123">                 <eventdescription lang="de">description_de</eventdescription>                 <eventdescription lang="en">descrition_en</eventdescription>             </event>             <event id="456">                 <eventdescription lang="de">description_de</eventdescription>                 <eventdescription lang="en">descrition_en</eventdescription>             </event>         </events>     </eventlist> </data>

i'm loading xml simplexml , loop on events:

$responsexml = simplexml_load_file($requesturl); $lang = 'de'; foreach($responsexml->eventlist->events->children() $event){     // eventdescription }

now want string/text ofthe eventdescription every event in right language based on $lang variable. if it's set de want descriptions attribute lang="de".

i've tried

echo( $event->eventdescription[0]);

which kinda works (assuming de , en in same order), using var_dump reveals, it's not string only

array (size=1)   0 =>      object(simplexmlelement)[3]       public '@attributes' =>          array (size=1)           'lang' => string 'de' (length=2)       public 0 => string 'description_de' (length=14)

so how string of eventdescription node? there better way make language selection should languages not in same order?

answered elsewhere, use xpath:

 $events = $responsexml->xpath('//data[eventlist[events[event[eventdescription[@lang="de"]]]]]');

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
