Question

Aloha everyone,

I have another question. I have a SYDI script that retrieves WMI data from Windows computers, then appends a timestamp to the end of the file, and finally saves it to a share on a server. The PHP code I have to read and print out the filenames is shown below:

if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            if ($file != "." && $file != "..") {
                $results[] = $file;
                echo $file . "<br />";
            }
        }
        closedir($dh);      
    }
}

Everything is good and the filenames are returned as shown below:

sydiResult-24-Apr-11-18-59-52.xml
sydiResult-24-Apr-11-19-00-32.xml
sydiResult-24-Apr-11-19-01-17.xml

I’ve tried to use simplexml to call the files, in order, to see if I could even do it, with the following code:

for ($i = 0; $i < sizeof($results); $i++) {
    $xml = simplexml_load_file($results[$i]);
}

but I get errors indicating that simplexml couldn’t open external xml files. The php file is in my htdocs directory, and the xml files are in a directory in the htdocs directory, called sydiResults. I wanted to separate the sydi xml files, so I decided to make the sub-directory. Could that be the reason simple xml won’t work?

My plan is simple: open an the xml files and extract certain information from it, then loop to the next xml file, extract certain information from it, then … so on and so on until I reach the last xml file in the directory. Does anyone have an idea of how I can use simplexml, or if I can use simplexml to open each xml file in turn?

Thanks in advance for any and all responses.

try this :

for ($i = 0; $i < sizeof($results); $i++) {
$file = 'sydiResults/'.$results[$i];
if (file_exists($file)) {
   $xml = simplexml_load_file($file);
    print_r($xml);
 }
else {
exit('Failed to open '.$file);
}
