Extract XML via PHP

I have the following xml-file (not generated by me and can't choose myself).  I'm using simplexml and I have no problems accessing third level elements such as

<Category catalogs="false" id="169901" name="Reise" refinements="false">

using the follwing code

$xml = simplexml_load_file($xml_url);

$CounterObj = count($xml->Category);

for($StartPunt=0; $StartPunt < $CounterObj; $StartPunt++)
{

echo $xml->Category[$StartPunt]['name'];

}

But I'm trying without success to access the level below too, such as:

<Category catalogs="false" id="171701" name="Charter- og Pakketur" refinements="true"/>

Here's the xml-file:

<CategorySearch format="Tree" id="601">

<Category catalogs="false" id="601" name="Home Page" refinements="false">

	<Category catalogs="false" id="169901" name="Reise" refinements="false">
		<Category catalogs="false" id="171701" name="Charter- og Pakketur" refinements="true"/>
		<Category catalogs="false" id="172001" name="Ferje" refinements="false"/>
		<Category catalogs="false" id="100365023" name="Fly og hotell" refinements="false"/>
		<Category catalogs="false" id="172201" name="Flybilletter" refinements="false"/>
		<Category catalogs="false" id="170701" name="Hoteller" refinements="false"/>
		<Category catalogs="false" id="172301" name="Leiebil" refinements="false"/>
		<Category catalogs="false" id="100502023" name="Priskalender flybilletter" refinements="false"/>
		<Category catalogs="false" id="100425123" name="Reiseprodukter" refinements="false"/>
	</Category>

	<Category catalogs="false" id="110101" name="Data, Utstyr, Internett" refinements="false">

		<Category catalogs="false" id="100324323" name="Grafikk og fremvisning" refinements="false">
		<Category catalogs="true" id="127201" name="Projektorer" refinements="false"/>
		<Category catalogs="true" id="115401" name="Skannere" refinements="false"/>
		<Category catalogs="true" id="114401" name="Skjermer" refinements="false"/>
		<Category catalogs="true" id="114901" name="Skrivere" refinements="false"/>
		<Category catalogs="true" id="100052213" name="Alt-i-ett skrivere" refinements="false"/>
		<Category catalogs="true" id="116901" name="Nettverk- og Webkameraer" refinements="false"/>
	</Category>
</Category>
</CategorySearch>

Do I have to loop through it in some way? Or is there another solution?

Thanks in advance.

this is really very strange XML...

you should be able to access thoses nodes with

$xml->Category->Category;

$xml = simplexml_load_file($xml_url);

foreach ($xml->Category as $cat) {
echo $cat['name'].'<br/>';
foreach ($cat as $cat2) {
	echo '    - '.$cat2['name'].'<br/>';
	foreach ($cat2 as $val) {
		echo '        - '.$val['name'].'<br/>';
	}
}
}

Never used simplexml before but i guess this works

Thanks guys. Buddski, your piece of code is outputing the level above the level I want to output. In other words I want one Category step deeper.

Any idea?

When I tested that script i was returned with (using your xml)

[pre]Home Page

    - Reise

        - Charter- og Pakketur

        - Ferje

        - Fly og hotell

        - Flybilletter

        - Hoteller

        - Leiebil

        - Priskalender flybilletter

        - Reiseprodukter

    - Data, Utstyr, Internett

        - Grafikk og fremvisning

        - Projektorer

        - Skannere

        - Skjermer

        - Skrivere

        - Alt-i-ett skrivere

        - Nettverk- og Webkameraer[/pre]Which is as deep as that XML goes..

I generally find that displaying the structure, as simplexml/php sees it, helps determine how to access it -

echo "<pre>",print_r($xml,true),"</pre>";

You can put any level into the above to see what it looks like, such as -

echo "<pre>",print_r($xml->Category->Category,true),"</pre>";

Hmm...strange. I'll dig in and check for errors. Thanks!

Thanks PFMaBiSmAd. Will have a look at it.

Buddski! You're the man! Thank you. I had a small typing error which caused the problem.
