XML parsing of new lines on PHP4 and PHP5

[yawnmoth]

Say I have the following script:

<?php
$contents="<p>t est\ntest</p>";

$xml_parser = xml_parser_crea te('UTF-8'); // try xml_parser_crea te_ns,
too.
xml_set_charact er_data_handler ($xml_parser,'h andler');
xml_parse($xml_ parser, $contents);

function handler($parser , $data)
{
static $count=1;
echo "$count. $data<br />";
$count++;
}
?>

When ran on PHP4 (via the web, so new lines are seen as spaces) I get
this:

1. test
2.
3. test

When ran on PHP5 (via the web) I get this:

1. test test

Why the difference? Is there any way to get PHP5 to simulate PHP4's
behavior?
