<?xml version="1.0" encoding="utf-8" ?>
<items>
<aaa>
</aaa>
<aaa>
</aaa>
<aaa>
<bbb>
</bbb>
<bbb>
</bbb>
<bbb>
<ccc>
Only this childnod what I need
</ccc>
<ccc>
And this one
</ccc>
</bbb>
</aaa>
</items>
I want parse the XML as given above with PHP. I don't know how to get these two child nodes.
When I use the code below, it triggers the error: Warning: main() [function.main]: Cannot add element bbb number 2 when only 0 such elements exist in
<?php
header('Content-type:text/html; charset=utf-8');
$xml = simplexml_load_file('2.xml');
foreach ($xml->aaa[2]->bbb as $bbb){
echo $bbb[2]->$ccc; // wrong in here
echo $bbb[3]->$ccc;
}
?>
Use xpath
$ccc = $xml->xpath('aaa/bbb/ccc');
foreach($ccc as $c){
echo (string)$c."<br/>";
}
Result:
Only this childnod what I need
And this one
Also, in your initial attempt, $bbb[3]
does not make sense because you have three items only, starting with index 0.
I don't know how to use the return of simplexml, but from what I have seen from your code, this should work:
<?php
header('Content-type:text/html; charset=utf-8');
$xml = simplexml_load_file('2.xml');
echo $xml->aaa[2]->bbb[2]->ccc[0];
echo $xml->aaa[2]->bbb[2]->ccc[1];
?>
