SimpleXML-Load Child-getting获取属性

Question

I've got the following problem and I can't find my mistake probably?

I try load the following XML(Over 15k Lines) Structure:

<Config>
  <SystemFiles>
  <Core>
    <Info>
    <Network>
    <Capture>
    <Store>
      <Mount01>
      <Mount02>
    </Store>
  </Core>
</Config>

I need access to the Substructure of Store with each Child of it. My function looks like:

  public static function get_storage_data()
  {
    if(file_exists('/var/www/content/data/data.xml')) :
        $xml = simplexml_load_file('/var/www/content/data/data.xml');
        foreach ($xml->Config->Core->Store->children() as $mount) {
          echo $mount;
        }
    else:
        write_log(sprintf("data.xml not found"));
    endif;
  }

Which generates the following errors (Line 8 is the foreach line):

Notice
: Trying to get property 'Store' of non-object in
/var/www/inc/storage.inc
on line
8

Fatal error
: Uncaught Error: Call to a member function children() on null in /var/www/inc/storage.inc:8 Stack trace: #0 /var/www/storage.php(30): Storage::get_storage_data() #1 {main} thrown in
/var/www/inc/storage.inc
on line
8

What did I forget here or what is my mistake? Thanks!

You don't need to include the root node name when using SimpleXML to parse XML - it's already anchored at that level.

You should just be able to change the path from

$xml->Config->Core->Store->children()

to

$xml->Core->Store->children()

Note: I'm assuming that your <Mount01> and <Mount02> nodes just contain text content, since you won't be able to echo them otherwise.

See here for a worked example: https://eval.in/1006543
