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];

}

case folding is a violation of the XHTML specification. xhtml is all in lowercase to be inline with the DOM

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

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

XML_OPTION_SKIP_WHITE =1 allows the parser to skip "space" characters in xml document (default is 0)

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