XML log file

Hello again ;-)

About the file "db-log.xml" I have to create It or it is created automatically (apache has the permission to create it...)?

To do a test, I've set:
define('DB_LOG_XML',TRUE);
define('DB_URL_XML','/home/valentino/db-log.xml');

But executing only the FIRST EXAMPLE query (copied from index.php file, and changed with my parameters) I can see the array with the results, but I receive this message at the end of the page:

Notice: Undefined variable: xml in /home/ads/public_html/mysql/mysql.class.php on line 387

Fatal error: Call to a member function addChild() on a non-object in /home/ads/public_html/mysql/mysql.class.php on line 387


What does It mean?

Thank you.

Hi

I think I've found the problem:

The lines 383 and 384 are:
if (file_exists(DB_URL_XML)) if (!$xml = @simplexml_load_file(DB_URL_XML)) $this->logError('[all]',0,'fatal','Log file exists, but I couldn\'t read it! Please check file permissions or disk array!');
else $xml = simplexml_load_string('<?xml version="1.0" encoding="UTF-8"?><db_log></db_log>');

Adding compound brackets, It is:
if (file_exists($this->db_url_xml)) {
if (!$xml = @simplexml_load_file($this->db_url_xml)) {
$this->logError('[all]',0,'fatal','Log file exists, but I couldn\'t read it! Please check file permissions or disk array!');
} else {
$xml = simplexml_load_string('<?xml version="1.0" encoding="UTF-8"?><db_log></db_log>');
}
}

that could be (i think) wrong.

I've changed that lines with:
if (file_exists($this->db_url_xml)) {
if (!$xml = @simplexml_load_file($this->db_url_xml)) {
$this->logError('[all]',0,'fatal','Log file exists, but I couldn\'t read it! Please check file permissions or disk array!');
}
} else {
$xml = simplexml_load_string('<?xml version="1.0" encoding="UTF-8"?><db_log></db_log>');
}

And now It works; creating the log file (If not exists) and writing the XML inside.

Let me know If I've wrong.
Thank you.
But I think

some time ago i've had some problems also with this function, bit I never looked further into it.
I guess I'll include your changes into the next version (Obviously with the credits :) )

Greetings and thanks !
