PHP - Iterate Though Additonial XML Node -

-

i working following xml response structure:

<compressedvehicles> <f> <rs>  <r>     <vs>         <v />         <v />     </vs> </r> <r>     <vs>         <v />         <v />     </vs> </r> </rs> </f> </compressedvehicles>

so far, guidance fellow stack overflow member, able construct working json output based on following php code:

header('content-type: application/json');  $xml  = simplexml_load_file( 'inventory.xml' ); $compressedvehicles = $xml->compressedvehicles;  $attributes = array(); foreach( $compressedvehicles->f->attributes() $key => $val ) {     $attributes[$key] = $val->__tostring(); }  $data = array(); foreach( $compressedvehicles->f->rs->r->vs->v $vehicle ) {     $line = array();     foreach( $vehicle->attributes() $key => $val ) {     $line[$attributes[$key]] = $val->__tostring(); } $data[] = $line; }  $json = json_encode($data); echo $json;

this iterates through single <r> node before completion. how can append code iterate through each <r> node well?

thank in advance.

right now, you're directly going $compressedvehicles->f->rs->r->vs->v, modify loop each <r> node:

foreach( $compressedvehicles->f->rs->r $r ) {

this iterate each <r>.

then each <r>, add nest $vehicle:

foreach($r->vs->v $vehicle)  { // rest of code

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
