XML Parse into array - how to access values?

[Nematoth]

Hi there,

I am new to parsing XML with PHP and have found a class that has parsed my XML from AFP very nicely into a multidimensional array:

Array
(
    [NewsML] => Array
        (
            [Catalog attr] => Array
                (
                    [Href] => [URL unfurl="true"]http://www.afp.com/dtd/AFPCatalog.xml[/URL]
                )

            [Catalog] => 
            [NewsEnvelope] => Array
                (
                    [DateAndTime] => 20051107T233033Z
                )

            [NewsItem] => Array
                (
                    [Identification] => Array
                        (
                            [NewsIdentifier] => Array
                                (
                                    [ProviderId] => afp.com

                                )

                                        (

                                                (
                                                    [NewsItem] => 051107171104.nwi6annd.xml
                                                )

                                            [NewsItemRef] => 
                                        )

                                )

                        )

                )

        )

)

However... I cannot access the values at all..

For example.. I thought I could do this:

echo $data["NewsML"]["catalog"]["NewsItem"]["NewsComponent"]["NewsComponent"]["NewsLines"]["HeadLine"];

but this returns nothing..

How can I iterate through the [newComponent] array to display the headlines and the associated xml file with the content for that headline?

Any pointers greatly appreciated.. I have been banging my head for two days over this now.. :-(

Thanks.

You forgot the array index that determines which story to show.

echo $data["NewsML"]["catalog"]["NewsItem"]["NewsComponent"]["NewsComponent"][1]["NewsLines"]["HeadLine"];

If you want to iterate through all the items, you should use a for or foreach loop depending on whether your iterating through assiciative or numbered array indices.

Thanks.. wasn't quite right.. but it assisted in me solving the problem..

It is customary to explain the solution so that users after you could use this thread as a reference if suffering from the same problem. That way you give something back...

I was getting confused with all the multidimensional arrays so what I did was this:

	$newsArray = $data['NewsML']['NewsItem']['NewsComponent']['NewsComponent'];

	foreach($newsArray as $value)
	{
		foreach($value as $value2)
		{				
				if($value2['HeadLine']!="")
				{
					$headlineArr[] = $value2['HeadLine'];
				}
				if($value2['NewsItem']!="")
				{
					$xmlArr[] = $value2['NewsItem'];
				}				
		}
	}
[\code]

This gave me two simple arrays.. one with the headlines and one with the reference xml file attribute.. I was then able to display and link the a subsequent page that displayed the  xml data from the reference file using an xsl stylesheet.
