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 ...

}

?>

I'm a little confused about using xml_parser_set_option and xml_parser_get_option with XML_OPTION_SKIP_WHITE and XML_OPTION_SKIP_TAGSTART.



Looking at the source code, ...set_option() accepts both ...SKIP_WHITE and ...SKIP_TAGSTART, and sets a program variables.  On the other hand, ...get_option() returns an error for both.   I'm not sure of the code actually uses the variables properly, although it does reference the set variables.  This does look like an oversite.

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. 





<?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!

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

pupeno at pupeno dot com 15-Nov-2002 06:14


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.

More information on:

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

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.
