serialize XML Category

russellharrower · 09-15-2009, 04:31 PM

I have been working on this for around 2 days now, Having the same issue it seems that I can serialize the categories.

They return the following

Code:

Array ( [0] => SimpleXMLElement Object ( ) ) a:1:{i:0;O:16:"SimpleXMLElement":0:{}}

Does any one now how to fix this issue?

PHP Code:


			
<?php

  $feed = file_get_contents("http://www.techau.tv/blog/?feed=rss2");

  $xml = new SimpleXmlElement($feed);

  foreach ($xml->channel->item as $entry)

  {

    echo $entry->title.'<br/>';

    echo $entry->description.'<br/><br/>';

    

    $keywordsArray = array();

    foreach ($entry->category as $a => $b)

    {

      $keywordsArray[] = $b;

    }

    print_r($keywordsArray);

    //serialize keyword array ready for posting in link

    $keywords = str_replace(

      array('O:16:"SimpleXMLElement":0:{}', 'O:16:"SimpleXMLElement":'),

      array('s:0:"";', 'O:8:"stdClass":'),

      serialize($keywordsArray)

      );    

    print $keywords;

    print "<br/><br/>";

  }

?>

PHP Code:


			

$file = simplexml_load_file('http://www.techau.tv/blog/?feed=rss2');

print_r($file);

Done.

For simple XML adamdecaf's solution should work just fine. However, if you plan on parsing loosely-typed XML (like HTML) and you don't want to mangle the data then you will have to use the DOMDocument class to manually parse the XML.

I wrote a class for Dingo that safely serializes and de-serializes loosely-typed XML by using the DOMDocument class, but you won't be able to get your hands on that until Oct 1.
