..........................


and i want to use php ,select it and make a xml to save it ,now i use this
script

<?php

header("Content-type: text/xml");

$host = "localhost";
$user = "root";
$pass = "";
$database = "test";

$linkID = mysql_connect($host, $user, $pass) or die("Could not connect to
host.");
mysql_select_db($database, $linkID) or die("Could not find database.");

$query = "SELECT * FROM blog ORDER BY date DESC";
$resultID = mysql_query($query, $linkID) or die("Data not found.");

$xml_output = "<?xml version=\"1.0\"?>\n";
$xml_output .= "<entries>\n";

for($x = 0 ; $x < mysql_num_rows($resultID) ; $x++){
    $row = mysql_fetch_assoc($resultID);
    $xml_output .= "\t<entry>\n";
    $xml_output .= "\t\t<date>" . $row['date'] . "</date>\n";
        // Escaping illegal characters
        $row['text'] = str_replace("&", "&", $row['text']);
        $row['text'] = str_replace("<", "<", $row['text']);
        $row['text'] = str_replace(">", "&gt;", $row['text']);
        $row['text'] = str_replace("\"", "&quot;", $row['text']);
    $xml_output .= "\t\t<text>" . $row['text'] . "</text>\n";
    $xml_output .= "\t</entry>\n";
}

$xml_output .= "</entries>";

echo $xml_output;

 ?>

it has no problem,but i want to save a xml file ,like this format

<?xml version="1.0" encoding="GB2312"?>
<Table>
    <Record>
        <Title>a1</Title>
        <Author>a2</Author>
        <Content>a3</Content>
        <date>2003-06-29</date>
    </Record>
    <Record>
        <Title>b1</Title>
        <Author>b2</Author>
        <Content>b3</Content>
        <date>2003-06-30</date>
    </Record>
    ........
