Re: XML Parsing simpleXML Arrays Question

Hi List I have taken the advice of a number of people on the list and am back trying to write my XML parser using SimpleXML. I am having a problem and I believe the problem is my lack of understanding of arrays and simpleXML in spite of much google searching and manual reading. I would appreciate some help. The piece of XML I am parsing is as follows. I am working with a small section to see if I can get my head around it. <?xml version="1.0" encoding="UTF-8"?> <?ypsilon RNGSchema="fareResponse.rnc" type="compact"?> <fareResponse cntTarifs="122" offset="0"> <vcrSummary>

        <vcr minPrice="1667" maxPrice="1667" totalTarifs="1" currency="USD">AA</vcr>
        <vcr minPrice="1374" maxPrice="4704" totalTarifs="2" currency="USD">PR</vcr>

</vcrSummary> </fareResponse> If I use the following $file = "test.xml";

          $data = simplexml_load_file($file);
          Just to confirm your data structure, do a var_dump($data) right here and see what the output is

foreach ($data->vcrSummary as $vcrSummary)

          {
                var_dump($vcrSummary);        }

Then I get object(SimpleXMLElement)#5 (1) { ["vcr"]=> array(2) {

    [0]=>
    string(2) "AA"
    [1]=>
    string(2) "PR"

} } Which is pretty much what I would expect as there are 2 vcr tags. If I then use $file = "test.xml";

                $data = simplexml_load_file($file);

right here you, at least from the example above, you need to be using $data->vcrSummary as the first parameter of the foreach loop

        foreach($data as $vcrSummary)
        {
  then here I would be using another foreach loop, because the $vcrSummary->vcr is an array with two indexes 0 and 1...  So

foreach ( $vcrSummary->vcr AS $v ) { echo "{$v}\n"; }

                $z = $vcrSummary->vcr;
                print "$z \n";
                                }

I get 3 blank lines and then AA which is the first of the two vcr values. The examples I am looking at suggest I should have gotten both of the vcr values. Many of the examples I am looking at say to use echo instead of print, eg echo $vcrSummary->vcr; if done correctly, this should echo "Array" and maybe a warning. :(

and that just gives me AA and not both values that I would expect. Can anyone point me in the right direction here. Regards,
