xml entity problem

[Jos van Uden]

Can somebody explain why the following file
has the wrong output:

<?xml version="1.0" encoding="iso-8859-1"?>
<test>
<elem>‘bla bla bla’</elem>
</test>

Expected: ‘bla bla bla’
output: ?bla bla bla?

It's not caused by the browser, but
by the xml parser.

Thanks.


test script:


<?php

$file = "test.xml";
$testdata;
$tagname;

function startElement($p arser, $name, $attrs) {
global $tagname;
$tagname = $name;
}

function endElement($par ser, $name) {
}

function characterData(& $parser, $data) {
global $testdata, $tagname;
if(trim($data) != "") {
switch($tagname ) {
case 'ELEM' :
$testdata .= $data;
break;
}
}
}

$xml_parser = xml_parser_crea te();
xml_set_element _handler($xml_p arser, "startEleme nt", "endElement ");
xml_set_charact er_data_handler ($xml_parser, 'characterData' );
if (!($fp = fopen($file, "r"))) {
die("could not open XML input");
}

while ($data = fread($fp, 4096)) {
if (!xml_parse($xm l_parser, $data, feof($fp))) {
die(sprintf("XM L error: %s at line %d",
xml_error_strin g(xml_get_error _code($xml_pars er)),
xml_get_current _line_number($x ml_parser)));
}
}
xml_parser_free ($xml_parser);

print "output : " .$testdata;


?>

_I know_ this sounds silly. But try
<?php echo '<'.'?xml version="1.0" encoding="iso-8859-1"?'.'>'; ?>

(that's one thing that feedvalidator drove me to do... ^^; Still having
problems, though, so if there is a specialist of RSS feed here, I'll be
happy to have help ;-) )
