Selecting the 'Current' XML Record

Recommended Posts

I have php code that uses an XML file to display in an HTML page the 'Next' and 'Previous' pages for that page.

 

The code currently selects ALL of the XML records and then displays them on the page.  What I would like to be able to do is have the HTML only display the next and previous links for the current page. 

 

What would be the best way to do this?

 

Perhaps Select only where the XML Title = the HTML page title?

 

???

 

XML

 

<?xml version="1.0" encoding="ISO-8859-1"?>
<Listings>
<Count>2</Count>
<Listing>
<Title><![CDATA[Food and Drink]]></Title>
<PREVURI>http://www.page.nl</PREVURI>
<NEXTURI>http://www.page.nl/info/Location.php</NEXTURI>
</Listing>
<Listing>
<Title><![CDATA[Location]]></Title>
<PREVURI>http://www.page.nl/Food-and-Drink/index.php</PREVURI>
<NEXTURI>http://www.page.nl/info/Facilities.php</NEXTURI>
</Listing>
</Listings>

 

PHP

 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>

<body>


<?php

// read xml file into string
$text = file_get_contents("sample.xml");

if(!$text) {
die("ERROR: Unable to read file");
}

// parse the xml into structure
$p = xml_parser_create();
xml_parser_set_option($p, XML_OPTION_CASE_FOLDING, 0);
xml_parse_into_struct($p, $text, $vals, $index);
xml_parser_free($p);

// read data of interest from structure into array:
for($i=0; $i<$index['Listings'][1]; $i++)
{
foreach(array('Title', 'PREVURI', 'NEXTURI') as $key)
{
$data[$i][$key] = $vals[$index[$key][$i]]['value'];
}
}

// output HTML:
foreach($data as $val)
{
echo <<<XML
<a href="{$val['PREVURI']}"><small>PREVIOUS</small></a>
<h3>{$val['Title']}</h3>
<a href="{$val['NEXTURI']}"><small>NEXT</small></a>
<br>
XML;
}
?>

</body>
</html>
