can't access xml node PHP - php

Question

I have a page in php where I have to parse an xml.
I have done this for example:
$hotelNodes = $xml_data->getElementsByTagName('Hotel');
foreach($hotelNodes as $hotel){
$supplementsNodes2 = $hotel->getElementsByTagName('BoardBase');
foreach($supplementsNodes2 as $suppl2) {
echo'<p>HERE</p>'; //not enter here
}
}
}
In this code I access to each hotel of my xml, and foreach hotel I would like to search the tag BoardBase but it doesn0t enter inside it.
This is my xml (cutted of many parts!!!!!)
<hotel desc="DESC" name="Hotel">
<selctedsupplements>
<boardbases>
<boardbase bbpublishprice="0" bbprice="0" bbname="Colazione Continentale" bbid="1"></boardbase>
</boardbases>
</selctedsupplements>
</occupancy></occupancies>
</hotel>
I have many nodes that doesn't have BoardBase but sometimes there is but not enter.
Is possible that this node isn't accessible?
This xml is received by a server with a SoapClient.
If I inspect the XML printed in firebug I can see the node with opacity like this:
I have also tried this:
$supplementsNodes2 = $hotel->getElementsByTagName('boardbase');
but without success

2 issues I can see from the get-go: XML names are case-sensitive, hence:
$hotelNodes = $xml_data->getElementsByTagName('Hotel');
Can't work, because your xml node looks like:
<hotel desc="DESC" name="Hotel">
hotel => lower-case!
As you can see here:
[...] names for such things as elements, while XML is explicitly case sensitive.
The official specs specify tag names as case-sensitive, so getElementsByTagName('FOO') won't return the same elements as getElementsByTagName('foo')...
Secondly, you seem to have some tag-soup going on:
</occupancy></occupancies>
<!-- tag names don't match, both are closing tags -->
This is just plain invalid markup, it should read either:
<occupancy></occupancy>
or
<occupancies></occupancies>
That would be the first 2 ports of call.
I've set up a quick codepad using this code, which you can see here:
$xml = '<hotel desc="DESC" name="Hotel">
<selctedsupplements>
<boardbases>
<boardbase bbpublishprice="0" bbprice="0" bbname="Colazione Continentale" bbid="1"></boardbase>
</boardbases>
</selctedsupplements>
<occupancy></occupancy>
</hotel>';
$dom = new DOMDocument;
$dom->loadXML($xml);
$badList = $dom->getElementsByTagName('Hotel');
$correctList = $dom->getElementsByTagName('hotel');
echo sprintf("%d",$badList->lenght),
' compared to ',
$correctList->length, PHP_EOL;
The output was "0 compared to 1", meaning that using a lower-case selector returned 1 element, the one with the upper-case H returned an empty list.
To get to the boardbase tags for each hotel tag, you just have to write this:
$hotels = $dom->getElementsByTagName('html');
foreach($hotels as $hotel)
{
$supplementsNodes2 = $hotel->getElementsByTagName('boardbase');
foreach($supplementsNodes2 as $node)
{
var_dump($node);//you _will_ get here now
}
}
As you can see on this updated codepad.

Alessandro, your XML is a mess (=un casino), you really need to get that straight. Elias' answer pointed out some very basic stuff to consider.
I built on the code pad Elias has been setting up, it is working perfectly with me:
$dom = new DOMDocument;
$dom->loadXML($xml);
$hotels = $dom->getElementsByTagName('hotel');
foreach ($hotels as $hotel) {
$bbs = $hotel->getElementsByTagName('boardbase');
foreach ($bbs as $bb) echo $bb->getAttribute('bbname');
}
