Getting file sizes

[graham23s]

Hi Guys,

 

what im trying to do here is calculate file sizes in an .xml file for example this is the bit i need to calculate:

 

    <segments>
      <segment number="1" bytes="259072">[email protected]</segment>
      <segment number="2" bytes="259072">[email protected]</segment>
      <segment number="3" bytes="259072">[email protected]</segment>
      <segment number="4" bytes="259072">[email protected]</segment>
      <segment number="5" bytes="259072">[email protected]</segment>
      <segment number="6" bytes="259072">[email protected]</segment>
      <segment number="7" bytes="259072">[email protected]</segment>
      <segment number="8" bytes="259072">[email protected]</segment>
      <segment number="9" bytes="259072">[email protected]</segment>
      <segment number="10" bytes="259072">[email protected]</segment>
      <segment number="11" bytes="259072">[email protected]</segment>
      <segment number="12" bytes="259072">[email protected]</segment>
      <segment number="13" bytes="259072">[email protected]</segment>
      <segment number="14" bytes="259072">[email protected]</segment>
      <segment number="15" bytes="259072">[email protected]</segment>
      <segment number="16" bytes="259072">[email protected]</segment>
      <segment number="17" bytes="259072">[email protected]</segment>
      <segment number="18" bytes="259072">[email protected]</segment>
      <segment number="19" bytes="259072">[email protected]</segment>
      <segment number="20" bytes="259072">[email protected]</segment>
      <segment number="21" bytes="259072">[email protected]</segment>
      <segment number="22" bytes="259072">[email protected]</segment>
      <segment number="23" bytes="259072">[email protected]</segment>
      <segment number="24" bytes="259072">[email protected]</segment>
      <segment number="25" bytes="259072">[email protected]</segment>
      <segment number="26" bytes="259072">[email protected]</segment>
      <segment number="27" bytes="259072">[email protected]</segment>
      <segment number="28" bytes="259072">[email protected]</segment>
      <segment number="29" bytes="259072">[email protected]</segment>
      <segment number="30" bytes="259072">[email protected]</segment>
      <segment number="31" bytes="259072">[email protected]</segment>
      <segment number="32" bytes="259072">[email protected]</segment>
      <segment number="33" bytes="259072">[email protected]</segment>
      <segment number="34" bytes="259072">[email protected]</segment>
      <segment number="35" bytes="259072">[email protected]</segment>
      <segment number="36" bytes="259072">[email protected]</segment>
      <segment number="37" bytes="259072">[email protected]</segment>
      <segment number="38" bytes="259072">[email protected]</segment>
      <segment number="39" bytes="259072">[email protected]</segment>
      <segment number="40" bytes="259072">[email protected]</segment>
      <segment number="41" bytes="259072">[email protected]</segment>
      <segment number="42" bytes="259072">[email protected]</segment>
      <segment number="43" bytes="259072">[email protected]</segment>
      <segment number="44" bytes="259072">[email protected]</segment>
      <segment number="45" bytes="259072">[email protected]</segment>
      <segment number="46" bytes="259072">[email protected]</segment>
      <segment number="47" bytes="259072">[email protected]</segment>
      <segment number="48" bytes="259072">[email protected]</segment>
      <segment number="49" bytes="259072">[email protected]</segment>
      <segment number="50" bytes="259072">[email protected]</segment>
      <segment number="51" bytes="259072">[email protected]</segment>
      <segment number="52" bytes="259072">[email protected]</segment>
      <segment number="53" bytes="259072">[email protected]</segment>
      <segment number="54" bytes="259072">[email protected]</segment>
      <segment number="55" bytes="259072">[email protected]</segment>
      <segment number="56" bytes="259072">[email protected]</segment>
      <segment number="57" bytes="259072">[email protected]</segment>
      <segment number="58" bytes="259072">[email protected]</segment>
      <segment number="59" bytes="259072">[email protected]</segment>
      <segment number="60" bytes="259072">[email protected]</segment>
      <segment number="61" bytes="25600">[email protected]</segment>
    </segments>

 

using a preg_match_all i can count the number of 'bytes=' but is there a way i can extract the value of bytes, then i can times it by the number of preg_match_all results or is there a better way?

 

thanks guys

Simple XML

$xml = simplexml_load_file('file.xml');
$size = 0;
foreach($xml->segments->segment as $segment)
$size += $segment['bytes'];

 

DOM XML

$xml = domxml_open_file('file.xml');
$segments = $xml->getElementsByTagName('segments')->item(0);
$segments = $segments->getElementsByTagName('segment');
$size = 0;
foreach($segments as $segment)
  $size += $segment->getAttribute('bytes');

Hi Mate,

 

thanks for that, this is the code for reading the .xml:

 

     $filecontent = file_get_contents("nzbs/$renamed_nzb");
     $xml = simplexml_load_string($filecontent);
     
     $nzbpiece = 0;
    
     foreach($xml->{"file"} as $nfile) {
     
        $nposter = (string) trim($nfile['poster']);
        $nposter = ($nposter);
                    
        $ndate = 0 + trim($nfile['date']);
                    
        $nsubject = (string) trim($nfile['subject']);
        // To find num of segments in subject:
        $nsubjsegs = 0 + subj_seg($nsubject);
        
        // To find out if Par or not
        $npar = (stristr($nsubject, "par2")?0:1);
        
        $nsubject = ($nsubject);
                    
        $groups = array();
        foreach($nfile->groups->group as $group) {
              $groups[] = (string) trim($group);
        }
        
        $ngroups = (serialize($groups));
                               
        //$nsegcount = 0;
        //$nsize = 0;
        //foreach($nfile->segments->segment as $segment) {
        //      $nbytes = 0 + trim($segment['bytes']);
        //      $nsize += $nbytes;
        //      $nsegcount++; 
        //}
                          
      }
      
        $size = 0;
        foreach($xml->segments->segment as $segment)
        $size += $segment['bytes'];
        
        echo $size;
      
      $matchesfound = preg_match_all('/subject="/', $filecontent, $matchfound);
      
      ## strtolower the files incase some par2's are uppercase
        
      $parsfound = preg_match_all("/.par2/", strtolower($filecontent), $parfind);

 

when i do the code above it produces a 0 instead of the actual amount have i implemented it ok?

 

cheers
