Liste de paramètres


Une référence vers un analyseur XML.


L'option à modifier. Voir ci-dessous.

Les options suivantes sont disponibles :

Options de l'analyseur XML
Option Type de données Description
XML_OPTION_CASE_FOLDING bool Contrôle la gestion de la casse des balises de cet analyseur XML. Par défaut, activé.
XML_OPTION_SKIP_TAGSTART bool Spécifie combien de caractères doivent être éludés du début du nom de la balise.
XML_OPTION_SKIP_WHITE entier Élude ou non les valeurs contenant des caractères blancs.
XML_OPTION_TARGET_ENCODING string Modifie le codage à la cible utilisé par cet analyseur XML. Par défaut, c'est celui qui a été spécifié lors de l'appel de xml_parser_create(). Les codages supportés sont ISO-8859-1, US-ASCII et UTF-8.


La nouvelle valeur de l'option.

Valeurs de retour

Renvoie true en cas de succès ou false en cas d'échec.

Erreurs / Exceptions

Lève une ValueError lorsque qu'une valeur invalide est passée à option.

Antérieur à PHP 8.0.0, passer une valeur invalide à option générait un avertissement E_WARNING et faisait retourner à la fonction la valeur false.


Version Description
8.3.0 Le paramètre value accepte désormais également les booléens. Les options XML_OPTION_CASE_FOLDING et XML_OPTION_SKIP_WHITE sont désormais des options booléennes.
8.0.0 parser attend une instance de XMLParser désormais; auparavent, une resource xml était attendue.
8.0.0 Une exception ValueError est désormais lancée si le option est invalide.

XML is case sensitive, then, from my point of view, disabling case folding doesn't goes against xml 1.0 specifications but the contrary, disabling case folding allow us to distiguish between diferent cases of the same letter ('a' and 'A') which of XML are two diferent things.
From my point of view, disabling case folding is a good practice and I think it should be disabled by default.

The option XML_OPTION_SKIP_WHITE has no effect in my PHP 5.2.6 (with expat-1.95.8-5). To skip cdata composed of white space only, simply check for that at the beginning of your cdata callback function:

function callback_cdata($parser, $cdata)

// ... continue processing ...

In the function below, you need to update two lines if you don't want php to throw warnings.

change these two:
$elements[$index]['attributes'] = $tag['attributes'];
$elements[$index]['content'] = $tag['value'];

to this:
$elements[$index]['attributes'] = empty($tag['attributes']) ? "" : $tag['attributes'];
$elements[$index]['content'] = empty($tag['value']) ? "" : $tag['value'];

A little mod to a function posted here...

function xml_to_array( $file )
$parser = xml_parser_create();
xml_parser_set_option( $parser, XML_OPTION_CASE_FOLDING, 0 );
xml_parser_set_option( $parser, XML_OPTION_SKIP_WHITE, 1 );
xml_parse_into_struct( $parser, file_get_contents($file), $tags );
xml_parser_free( $parser );

$elements = array();
$stack = array();
foreach ( $tags as $tag )
$index = count( $elements );
if ( $tag['type'] == "complete" || $tag['type'] == "open" )
$elements[$index] = array();
$elements[$index]['name'] = $tag['tag'];
$elements[$index]['attributes'] = $tag['attributes'];
$elements[$index]['content'] = $tag['value'];

if ( $tag['type'] == "open" )
{ # push
$elements[$index]['children'] = array();
$stack[count($stack)] = &$elements;
$elements = &$elements[$index]['children'];

if ( $tag['type'] == "close" )
{ # pop
$elements = &$stack[count($stack) - 1];
unset($stack[count($stack) - 1]);
return $elements[0];

Had one heck of a time getting curl to send my XML request. Tried a lot of different things, FINALLY ended up with this.

Im making a curl request to paymentech / Orbital 's payment gateway. Essentially, I took the same header i made for the fsockopen() request, and used it for this curl request. (Hostinc company didnt allow fsockopen().

You'll note that this specific gateway requires a custom content type header. Thats what gave me the most trouble. When using the CURLOPT_HTTPHEADER, and CURLOPT_POSTFIELDS together, it doesnt matter, it sends the default post header because of CURLOPT_POSTFIELDS.


= "";
$page = "/proccessing_page.cgi";

$post_string = "<YourXML>All XML stuff Here</YourXML>";

$header = "POST ".$page." HTTP/1.0 \r\n";
$header .= "MIME-Version: 1.0 \r\n";
$header .= "Content-type: application/PTI26 \r\n";
$header .= "Content-length: ".strlen($post_string)." \r\n";
$header .= "Content-transfer-encoding: text \r\n";
$header .= "Request-number: 1 \r\n";
$header .= "Document-type: Request \r\n";
$header .= "Interface-Version: Test 1.4 \r\n";
$header .= "Connection: close \r\n\r\n";
$header .= $post_string;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 4);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $header);

$data = curl_exec($ch); if (curl_errno($ch)) {
} else {

// use XML Parser on $data, and your set!

$xml_parser = xml_parser_create();
xml_parse_into_struct($xml_parser, $data, $vals, $index);

// $vals = array of XML tags. Go get em!


Worked like a dream for me. Enjoy!

XML_OPTION_SKIP_WHITE works for me (linux, php 4.2.1)

phpinfo says :

XML Support active
XML Namespace Support active
EXPAT Version expat_1.95.2

i guess it depends on expat version/presence

Re: anony at mous dot com
case folding is a violation of the XHTML specification. xhtml is all in lowercase to be inline with the DOM

The two 'skip' tags are not available to windows users using PHP 4.0.4. The following:

$skipWhite = xml_parser_get_option ($xmlParser,XML_OPTION_SKIP_WHITE);
$skipTagStart = xml_parser_get_option ($xmlParser,XML_OPTION_SKIP_TAGSTART);

generates the following errors:
Warning: xml_parser_get_option: unknown option in c:/program files/abria merlin/apache/htdocs/xml/sax_test.php on line 230

Disable case folding or your code will be violating the XML 1.0 specification.
