Read xml file

I've a ticker's code like this :
[html]
<?php
// load SimpleXML
$SECURITIES = new SimpleXMLElement('http://www.zet.com/xml/TableDt.xml', null, true);

echo <<<EOF
<marquee bgcolor="#333333" scrollamount="3" onmouseover=stop() onmouseout=start() ><font face='Time News Romance' font color='white' font size=4><table>


EOF;

foreach($SECURITIES as $STOCK) // loop
{
$change=$STOCK->Change;

echo "SYMBOL:{$STOCK->Symbol_code}&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
echo "PRICE:{$STOCK->Price}&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";

if($change==0)
{
echo "<img src='vang.gif'>$change</img>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
}
else
{
if($change>0)
{
echo "<img src='gre (2).gif'>$change</img>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
}
else
{
if($change<0)
{
echo "<img src='red.gif'>$change</img>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
}
}
}




}
echo '</table></marquee>';

?>[/html]

re: Read xml file

http://www.zet.com/xml/TableDt.xml does not exist, correct link?

If they update the XML it should not cause any problems for you. If the XML is being written, the web server will wait a period of time for the file to be come available (finished writing), then it gives you the XML.

is my understanding of your problem correct?

re: Read xml file

it have no problem from the link(link had given only for ex)
i get this xml file from the host and it will be updated from third party any morning from 7am-11am,this time my php page get error like that.(but it's ok when i refresh few times ,if refresh again ,again get error)
if dont have any solution for this can we hide the error page and appear a message :"loading page..." . can we do that?
