LIBXML_NOBLANKS option doesn't work for me and i don't understand why.

I have the following XML file:



<?xml version='1.0'?> 

<document>

    <title>Forty What?</title>

    <from>Joe</from>

    <to>Jane</to>

    <body>I know that's the answer -- but what's the question?</body>

    <blank></blank>

    <super attr='tel' attr2=' '>

        <ceva>test</ceva>

        <altceva attr="yes"/>

    </super>

</document>



I load it using:

$xml = simplexml_load_file('testxml.xml', NULL, LIBXML_NOBLANKS);



By using the parameter LIBXML_NOBLANKS i would expected to remove blank nodes such as <blank></blank> but instead when i display the array using print_r($xml) it looks like this:



<?php

SimpleXMLElement Object

(

    [title] => Forty What?

    [from] => Joe

    [to] => Jane

    [body] => I know that's the answer -- but what's the question?

    [blank] => SimpleXMLElement Object

        (

        )

    [super] => SimpleXMLElement Object

        (

            [@attributes] => Array

                (

                    [attr] => tel

                    [attr2] =>  

                ) 

            [ceva] => test

            [altceva] => SimpleXMLElement Object

                (

                    [@attributes] => Array

                        (

                            [attr] => yes

                        )

                )

        )

)

?>



Can anyone help me ?

Appreciate.

Note: The LIBXML_NOXMLDECL constant is defined in this library but is not supported by DOMDocument (yet).

<?php



print "PHP_VERSION:      ".PHP_VERSION."\n";

print "LIBXML_VERSION:   ".LIBXML_VERSION."\n";

print "LIBXML_NOXMLDECL: ".LIBXML_NOXMLDECL."\n";



$dom = new DomDocument();

$dom->loadXML("<foo />");



# This should work but doesn't.



print "DOMDocument doesn't honor LIBXML_NOXMLDECL:\n";

print $dom->saveXML(null,LIBXML_NOXMLDECL);



# This works, and will still work after the above is fixed.



print "Forwards compatible workaround:\n";

$lines = explode("\n", $dom->saveXML(null, LIBXML_NOXMLDECL), 2);

if(!preg_match('/^\<\?xml/', $lines[0]))

    print $lines[0];

print $lines[1];



?>



PHP_VERSION:      5.3.1-0.dotdeb.1

LIBXML_VERSION:   20632

LIBXML_NOXMLDECL: 2

DOMDocument doesn't honor LIBXML_NOXMLDECL:

<?xml version="1.0"?>

<foo/>

Forwards compatible workaround:

<foo/>
