  • 0

I have seen many PHP function on how to generate a <ul><li> tag but my array input is quite complicated I guess. It is an array returned from a custom function called xml2assoc

My question is how can I convert the returned xml2assoc array result to a <ul><li> formatted HTML code using PHP.

Thanks.

$tree = array(     0 => array(         'tag' => 'NavigationMode',         'value' => array(             0 => array(                 'tag' => 'Title',                 'value' => 'Introduction'             ),             1 => array(                 'tag' => 'NavigationNode',                 'value' => array(                     0 => array(                         'tag' => 'Title',                         'value' => 'Sub Intro'                     )                 )             )         )     ),     1 => array(         'tag' => 'NavigationMode',         'value' => array(             0 => array(                 'tag' => 'Title',                 'value' => 'Module 1'             )         )     ) );

The final output that I need to generate is like this:

<ul>     <li>     Introduction     <ul>         <li>Sub Intro</li>     </ul>     </li>      <li>Module 1</li> </ul>

  1. i didn’t test it for variations of the demo data …

    <?php  function getTitle($node) {     foreach ($node['value'] as $cnode) {             if ($cnode['tag'] == 'Title') {                 return $cnode['value'];             }     }      return 'untitled'; }  function getCNodes($node) {     $cnodes = array();      foreach ($node['value'] as $cnode) {         if ($cnode['tag'] == 'NavigationNode') {             $cnodes[] = $cnode;         }     }      return $cnodes; }  function runTree($node) {     $title  = getTitle($node);     $cnodes = getCNodes($node);      if (count($cnodes) > 0) {         $out = '<li>' . $title . '\n' . '<ul>';         foreach ($cnodes as $cnode) {             $out .= runTree($cnode);         }         $out .= '</ul>' . '\n' . '</li>' . '\n';          return $out;     } else {         return '<li>' . $title . '</li>' . '\n';     } }   $tree = array(     0 => array(         'tag' => 'NavigationMode',         'value' => array(                 0 => array(                         'tag' => 'Title',                         'value' => 'Introduction'                 ),                 1 => array(                         'tag' => 'NavigationNode',                         'value' => array(                                 0 => array(                                         'tag' => 'Title',                                         'value' => 'Sub Intro'                                 )                         )                 )         )     ),     1 => array(         'tag' => 'NavigationMode',         'value' => array(                 0 => array(                         'tag' => 'Title',                         'value' => 'Module 1'                 )         )     ) );    echo '<ul>'; foreach ($tree as $node) {     echo runTree($node); } echo '</ul>';  ?>
