How to create looped XML file from HTML in PHP? - php

Question

I would like to be able to create an XML file from some of the content of a html page. I have tried intensively but seem to miss something.
I have created two arrays, I have setup a DOMdocument and I have prepared to save an XML file on the server... I have tried to make tons of different foreach loops all over the place - but it won't work.
Here is my code:
<?php
$page = file_get_contents('http://www.halfmen.dk/!hmhb8/score.php');
$doc = new DOMDocument();
$doc->loadHTML($page);
$score = $doc->getElementsByTagName('div');
$keyarray = array();
$teamarray = array();
foreach ($score as $value) {
if ($value->getAttribute('class') == 'xml') {
$keyarray[] = $value->firstChild->nodeValue;
$teamarray[] = $value->firstChild->nextSibling->nodeValue;
}
}
print_r($keyarray);
print_r($teamarray);
$doc = new DOMDocument('1.0','utf-8');
$doc->formatOutput = true;
$droot = $doc->createElement('ROOT');
$droot = $doc->appendChild($droot);
$dsection = $doc->createElement('SECTION');
$dsection = $droot->appendChild($dsection);
$dkey = $doc->createElement('KEY');
$dkey = $dsection->appendChild($dkey);
$dteam = $doc->createElement('TEAM');
$dteam = $dsection->appendChild($dteam);
$dkeytext = $doc->createTextNode($keyarray);
$dkeytext = $dkey->appendChild($dkeytext);
$dteamtext = $doc->createTextNode($teamarray);
$dteamtext = $dteam->appendChild($dteamtext);
echo $doc->save('xml/test.xml');
?>
I really like simplicity, thank you.

You need to add each item in one at a time rather than as an array, which is why I build the XML for each div tag rather than as a second pass. I've had to assume that your XML is structured the way I've done it, but this may help you.
$page = file_get_contents('http://www.halfmen.dk/!hmhb8/score.php');
$doc = new DOMDocument();
$doc->loadHTML($page);
$score = $doc->getElementsByTagName('div');
$doc = new DOMDocument('1.0','utf-8');
$doc->formatOutput = true;
$droot = $doc->createElement('ROOT');
$droot = $doc->appendChild($droot);
foreach ($score as $value) {
if ($value->getAttribute('class') == 'xml') {
$dsection = $doc->createElement('SECTION');
$dsection = $droot->appendChild($dsection);
$dkey = $doc->createElement('KEY', $value->firstChild->nodeValue);
$dkey = $dsection->appendChild($dkey);
$dteam = $doc->createElement('TEAM', $value->firstChild->nextSibling->nodeValue);
$dteam = $dsection->appendChild($dteam);
}
}
