Closed 8 years ago.
I have a problem in XML files.
I searched through the internet and found lots of examples for my problem but I am not an expert on XML files and couldn't solve my problem. I want to do and XML file and work like RSS FEED. So, I am taking my data from my database and try to create the xml-code. Here what I have in my php file
(and it is not validated because of this problem: Undefined root element: channel)
<?php
include "connection.php";
//create the table with the fields
$rss_table = array();
$query = mysql_query("SELECT * FROM rssfeeds");
while($values_query = mysql_fetch_assoc($query))
{
$rss_table [] = array(
'title' => $values_query['title'],
'description' => $values_query['summary'],
'link' => $values_query['link']
);
}
$doc = new DOMDocument();
$doc->formatOutput = true;
$doc->encoding = "utf-8";
$r = $doc->createElement( "channel" );
$doc->appendChild( $r );
//$i=0;
foreach( $rss_table as $rss )
{
$b = $doc->createElement( "item" );
$title = $doc->createElement( "title" );
$title->appendChild(
$doc->createTextNode( $rss['title'] )
);
$b->appendChild( $title );
$description = $doc->createElement( "description" );
$description->appendChild(
$doc->createTextNode( $rss['description'] )
);
$b->appendChild( $description );
$link = $doc->createElement( "link" );
$link->appendChild(
$doc->createTextNode( $rss['link'] )
);
$b->appendChild( $link );
$r->appendChild( $b );
}
echo $doc->saveXML();
$doc->save("rssfeeds.xml")
?>
I want to have title - link - description
Simple one... nothing more
And here is what I get in rssfeeds.xml file:
<?xml version="1.0" encoding="utf-8"?>
<channel>
<item>
<title>winter week</title>
<description>You can come as you are! </description>

ok I found my one way .. I did it with FILES via php: this is the code if anyone needs help to that:
<?php
include "connection.php";
$myFile = "rss.xml";
$fh = fopen($myFile, 'w') or die("can't open file");
$rss_txt .= '<?xml version="1.0" encoding="utf-8"?>';
$rss_txt .= "<rss version='2.0'>";
$rss_txt .= '<channel>';
$query = mysql_query("SELECT * FROM rssfeeds");
while($values_query = mysql_fetch_assoc($query))
{
$rss_txt .= '<item>';
$rss_txt .= '<title>' .$values_query['title']. '</title>';
$rss_txt .= '<link>' .$values_query['link']. '</link>';
$rss_txt .= '<description>' .$values_query['summary']. '</description>';
$rss_txt .= '</item>';
}
$rss_txt .= '</channel>';
$rss_txt .= '</rss>';
fwrite($fh, $rss_txt);
fclose($fh);
?>
