ah, that will be this:

http://php.net/manual/en/ref.info.php#ini.magic-quotes-gpc

you have just learned to carefully study the differences between dev and 
production
php.ini settings (e.g. via phpinfo()) when you run into these kind of problems 
:-)

Hi Nathan!

Thank you for all your help!
Problem has been fixed...

The thing is, when request is sent, there is a little difference in what 
i get... I get  and so on...
These backslashes make the loadXML not load data properly... I've put an 
str_replace and the problem has been solved


Again... Thank you very much!

Re: [PHP] LoadXML trouble

[Dani Castaños]

that is expected behavior.  some of the internal classes dont define
any member variables that the php language has access to.  obviously
they are storing data internally, said variables just arent accessible as
member variables of the class thats being defined.


Ok! Thank you for this info...

But then...
Why can i do this in Windows:
$xml->getElementsByTagName( 'ticketID' )->item( 0 )->nodeValue;

and not in Linux?

-- Xml example:


1197027955_8310
OK
200

you can look at the structure of a class in one line with:
Reflection::export(new ReflectionClass('DomDocument'));

Re: [PHP] LoadXML trouble

If i use your script like this:

$xml = '

 1197027955_8310
 OK
 200
 
';

$obj = new DOMDocument();
$obj->loadXML( $xml );

echo print_r( $obj, true );
echo $obj->saveXML() . PHP_EOL;

The first statement writes:
DOMDocument Object
(
)

The second:


 1197027955_8310
 OK
 200
 


It's just the xml is not properly stored in loadXML method... but the 
string must be inside due to saveXML returns the proper value.

did the loadXML() method work in the test script i sent over in my 
last post?
if it does then something else is going on when loadXML() is called in 
the context

of your application.

The thing is... i'm trying to do something like this:

$request = $_POST['xml'];
$logger->debug( 'New ticket request' );

/**
 * Parse XML request to obtain values
 */
$xml = new DOMDocument();
//$xml->validateOnParse = true;
$xml->loadXML( $request );


you should always sanitize input.  at the very least you should be 
running $_POST['xml']

through a call to trim() before handing it to the DOMDocument  instance.

$request = trim($_POST['xml']);
$xml = new DOMDocument();
$xml->loadXML($request);

i suspect there is some garbage in or around the string contained in 
$_POST['xml'] that
the DomDocument instance doesnt like, therefore its not behaving the 
way youd anticipate.
for example if you modify the script i sent over last time by putting 
some spaces in between the
xml declaration and the opening tag of the envelope () you 
should see the following error

(or something similar [depending on the value of error_reporting])

Warning: DOMDocument::loadXML(): XML declaration allowed only at the 
start of the document in Entity,

line: 3 in /home/nathan/testDom.php on line 19

which consequently leads to


when invoking
echo $domDoc->saveXML() . PHP_EOL;
rather than


 1197026188_ec76
 KO
 500
 Internal Server Error


which is what you would expect.

RE: [PHP] LoadXML trouble

[ked]

first, create "dealxml.php" with ansi charset : 


  ked 
  tickcenter 
  train 
  back 
  1197026188_ec76 
  KO 
  500 
  Internal Server Error 

XML;
$xml = new DOMDocument();
//$xml->validateOnParse = true;
$xml->loadXML( $r );
$customer_id   = $xml->getElementsByTagName( 'customerID' )->item( 0
)->nodeValue;
$app_name  = $xml->getElementsByTagName( 'appName' )->item( 0
)->nodeValue;
$ticket_type   = $xml->getElementsByTagName( 'ticketType' )->item( 0
)->nodeValue;
$ticket_action = $xml->getElementsByTagName( 'ticketAction' )->item( 0
)->nodeValue; 
$ticket_params = $xml->getElementsByTagName( 'parameters' )->item( 0
)->childNodes;
echo "$customer_id ";
echo "$app_name ";
echo "$ticket_typed ";
echo "$ticket_action ";
echo "$ticket_params ";
?>

IE output :  

Warning: DOMDocument::loadXML() [function.loadXML]: Input is not proper
UTF-8, indicate encoding ! in Entity, line: 4 in W:\www\test\dealxml.php on
line 26

next , saved the dealxml.php as UTF-8 charset, then it works well.

I think that  the xml resource should be encoded by utf-8 charset, right or
wrong  ?  

My OS : win2000 , simplified chinese. Dose the OS blight  "DOMDocument" ?

have you been testing this in the context of your application, or have 
you also

tried a focused test script?  i would try something trivial, like:

The curious thing is that I've built this xml string with DOMDocument in 
my request... Then I suppose my Linux system has DOM support,

have you checked the contents of $request on the production machine

But when I have upload this code to production machine ( which runs

are the systems running the same major version of  php; and have you
