Hi all,

I am trying to create an RSS generator but getting the following code error in the code.

This is the error:

XML Parsing Error: XML or text declaration not at start of entity

and the is the code:

echo
'<?xml version="1.0" encoding="ISO-8859-1" ?>

It's pointing here:
<?xml version="1.0" encoding="ISO-8859-1" ?>
^

See arrow above...seems to be the first character?

Hope you can help

thanks

When I go to view source it has 3 blank links and then:

<?xml version="1.0" encoding="ISO-8859-1" ?>
<rss version="2.0">
etc...

How do I get rid of lose blank lines...or is that normal?

Full error is:

XML Parsing Error: XML or text declaration not at start of entity
Location: http://127.0.0.1/news/rssfeed.php
Line Number 4, Column 1:
<?xml version="1.0" encoding="ISO-8859-1"?>
^

Hi there,

It's those blank lines which are doing it is anything else "Echoing" before that code is run?
Is it part of a template engine or could you provide the full PHP code?

Kind regards

OK, See code attached
<?php
 include("../includes/dbconn.php");
 
 //the variables
$rss_title= "mysite.com RSS Feed";
 
$rss_site= "mysite.com" ;
 
$rss_description= "Welcome to mysite.com News RSS Feed!";
 
$rss_language="en";
 
$rss_logo="http://www.".$rss_site."/images/rss.jpg";
 
$emailadmin="st3vo@mysite.com"; 
 
header("Content-Type: text/xml;charset=iso-8859-1"); 
 
 
$query = "select * from tbl_news ORDER BY id DESC";
 
$result = mysql_query($query) or die("Query failed"); 
 
?>
 
<?php echo '<?xml version="1.0" encoding="ISO-8859-1"?>
<rss version="2.0">
<channel>
<title>'.$rss_title.'</title>
<link>http://www.'.$rss_site.'</link>
<description>'.$rss_description.'</description>
<language>en-en</language>
<image>
<url>'.$rss_logo.'</url>
<title>'.$rss_site.'</title>
<link>http://www.'.$rss_site.'</link>

{
 
//etc....

Without knowing what dbconn.php is outputting (if there are any spaces before or after the code in the file)
remove the space from line 25

infact... remove line 24,25 and 26 and check the dbconn.php file

kind regards

OK it now looks like this:

and the dbconn include is:

<?php
$con = mysql_connect("localhost","root","");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("db2", $con) or
  die('Could not select the database: '.mysql_error());


?>

hope this helps...still got the same error btw

<?php
 include("../includes/dbconn.php");
 
 //the variables
$rss_title= "mysite.com RSS Feed";
 
$rss_site= "mysite.com" ;
 
$rss_description= "Welcome to mysite.com News RSS Feed!";
 
$rss_language="en";
 
$rss_logo="http://www.".$rss_site."/images/rss.jpg";
 
$emailadmin="st3vo@mysite.com"; 
 
header("Content-Type: text/xml;charset=iso-8859-1"); 
 
 
$query = "select * from tbl_news ORDER BY id DESC";
 
$result = mysql_query($query) or die("Query failed"); 
 
echo '<?xml version="1.0" encoding="ISO-8859-1"?>
<rss version="2.0">
<channel>
<title>'.$rss_title.'</title>
<link>http://www.'.$rss_site.'</link>
<description>'.$rss_description.'</description>
<language>en-en</language>
<image>
<url>'.$rss_logo.'</url>
<title>'.$rss_site.'</title>
<link>http://www.'.$rss_site.'</link>
</image>'; 
 
//RSS loop 1
for($i=0;$i<6; $i++)
{
 
//etc....

I've just tested the code below seperately and a RSS reader reads it fine, what is producing the error?
	 //the variables
$rss_title= "mysite.com RSS Feed";
 
$rss_site= "mysite.com" ;
 
$rss_description= "Welcome to mysite.com News RSS Feed!";
 
$rss_language="en";
 
$rss_logo="http://www.".$rss_site."/images/rss.jpg";
 
$emailadmin="st3vo@mysite.com"; 
 
header("Content-Type: text/xml;charset=iso-8859-1"); 
 
	echo '<?xml version="1.0" encoding="ISO-8859-1"?>
	<rss version="2.0">
	<channel>
	<title>'.$rss_title.'</title>
	<link>http://www.'.$rss_site.'</link>
	<description>'.$rss_description.'</description>
	<language>en-en</language>
	<image>
	<url>'.$rss_logo.'</url>
	<title>'.$rss_site.'</title>
	<link>http://www.'.$rss_site.'</link>
	</image>';
