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:
<?php
function callback_cdata($parser, $cdata)
{
if(!trim($cdata))
return;
// ... continue processing ...
}
?>
xml_parser_set_option
(PHP 4, PHP 5, PHP 7, PHP 8)
xml_parser_set_option — Set options in an XML parser
Description
Sets an option in an XML parser.
Parameters
-
parser -
A reference to the XML parser to set an option in.
-
option -
Which option to set. See below.
The following options are available:
XML parser options Option constant Data type Description XML_OPTION_CASE_FOLDINGbool Controls whether case-folding is enabled for this XML parser. Enabled by default. XML_OPTION_SKIP_TAGSTARTinteger Specify how many characters should be skipped in the beginning of a tag name. XML_OPTION_SKIP_WHITEbool Whether to skip values consisting of whitespace characters. XML_OPTION_TARGET_ENCODINGstring Sets which target encoding to use in this XML parser.By default, it is set to the same as the source encoding used by xml_parser_create(). Supported target encodings are ISO-8859-1,US-ASCIIandUTF-8. -
value -
The option's new value.
Return Values
Returns true on success or false on failure.
Errors/Exceptions
Throws a ValueError when an invalid value is passed
to option.
Prior to PHP 8.0.0, the function returned false when passing an invalid
value to
option generated a E_WARNING
as well as making the function return false.
Changelog
| Version | Description |

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'];

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.
<?php
$url = "https://example.com";
$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($ch)) {
print curl_error($ch);
} else {
curl_close($ch);
}
// use XML Parser on $data, and your set!
$xml_parser = xml_parser_create();
xml_parser_set_option($xml_parser,XML_OPTION_CASE_FOLDING,0);
xml_parser_set_option($xml_parser,XML_OPTION_SKIP_WHITE,1);
xml_parse_into_struct($xml_parser, $data, $vals, $index);
xml_parser_free($xml_parser);
// $vals = array of XML tags. Go get em!
?>
Worked like a dream for me. Enjoy!

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.

Thank you.

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.

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];
}
