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

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

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.

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

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

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'];

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.

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];
}
