Question

I have source XML here: http://www.grilykrby.cz/rss/pf-heureka.xml. I want to use this xml feed and create another modified on my own server. I would like to change every node CATEGORYTEXT which contains word Prislusenstvi. I just tried something but I got only the listing of all categories without changing XML 🙁
Here is the example of my code. The row $kategorie=”nejaka kategorie”; doesn’t work.

<?php
$file = "http://www.grilykrby.cz/rss/pf-heureka.xml";
$xml=simplexml_load_file($file);
foreach ($xml->xpath('//SHOPITEM/CATEGORYTEXT') as $kategorie) {
echo $kategorie."<br />";
$kategorie="nejaka kategorie";
}
file_put_contents('test.xml', $xml->asXML()); 
?>

Answer 1

$kategorie is just a temp variable used in the loop which contains a copy of the data returned by xpath query. You would need to actually set the value directly in the $xml object.

I would personally also consider doing a str_replace or preg_replace within the XML content itself before parsing it into a simpleXML object.

Final Accepted Answer

<?php
$xml = simplexml_load_file('http://www.grilykrby.cz/rss/pf-heureka.xml');
$i=0;
foreach($xml -> SHOPITEM as $polozka) {
    if ($polozka -> CATEGORYTEXT == "Příslušenství") $xml -> SHOPITEM[$i] -> CATEGORYTEXT = "Some other text";
    $i++;
}
?>
