i'm a complete newbie... if statement not working

agoni

Ok now I have a problem.....

I got this class for parseing and writing xml files in php I got it from here: http://minixml.psychogenic.com/ it's called miniXML, don't know if you are familiar with it or not, anyway my problem is that my for loop dosen't appear to be firing... I can't work out why 🙁

Here is the code:

<?PHP
include_once("minixml.inc.php");
?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> 
<title>Untitled mock Document</title> 
</head> 
<BODY> 
<?PHP $timeoffset = time() - ((16*60)*60); 
$date = date("d/m/y"); 
$time = date("G:i",$timeoffset); 
$fp = fopen("test.xml", "r"); 
$xmlstring = fgets($fp, 1024); 
fclose($fp); 
$parsedDoc = new MiniXmlDoc(); 
$parsedDoc->fromString($xmlstring);
$rootEl =& $parsedDoc->getRoot();
echo "date ", $date, "@", $time, "<br><br>\n"; 
echo "location ", $location, "<BR><BR>\n"; 
echo "listening to ", $listeningto, "<BR><BR>\n"; 
echo "thinking about", $thinking, "<BR><BR>\n"; 
echo "mood", $mood, "<BR><BR>\n"; 
echo "2 words", $word1, $word2, "<BR><BR>\n"; 
echo "blank1", $blank1, $blank1answer, "<BR><BR>\n"; 
echo "blank2", $blank2, $blank2answer,"<BR><BR>\n"; 
echo "stress level", $stress, "%<BR><BR>\n\n\n"; 
echo "before for loop"; $elChildren =& $rootEl->getAllChildren(); 
for ($i=0; $i < $rootEl->numChildren(); $i++) {
	$nName = $elChildren[$i]->name();
	$nValue = $elChildren[$i]->getValue;
	print "$nName\n";
	echo "for loop";
	print "$nValue\n\n\n";
};
?>
</BODY>
</HTML>

Don't worry about the undefined variables in the echo statements as these are being posted to this file from another file.

Any clues???

get rid of the ";" in the for loop and it should work

for ($i=0; $i < $rootEl->numChildren(); $i++) {
$nName = $elChildren[$i]->name();
$nValue = $elChildren[$i]->getValue;
print "$nName\n";
echo "for loop";
print "$nValue\n\n\n";
}; <---- I believe Tim is talking about this one...

Should be just:

for ($i=0; $i < $rootEl->numChildren(); $i++) { 
    $nName = $elChildren[$i]->name(); 
    $nValue = $elChildren[$i]->getValue; 
    print "$nName\n"; 
    echo "for loop"; 
    print "$nValue\n\n\n"; 
}

Yep that one sorry forgot to tell where it was.

hey guys, i've just tried that but still no luck 🙁 i posted this same message on code walkers and someone suggested i try printing the count condition, this is being outputed as 0 which would obviously cause the loop to never fire as the condition is never true. i think it's something to do with whichever node i'm pointing at on the xml document (http://suckmyrazor.org/testphp/test.xml)

any of you guys have any experience with miniXML ? or do you know of any other way of achieving this? i'm basically trying to read from and then update an xml file.

many thanks for your help.
