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);
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);
foreach($data as $vcrSummary)
{
$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;
and that just gives me AA and not both values that I would expect.
Can anyone point me in the right direction here.

XML;
$xml = simplexml_load_string($string);
echo "VCR - 0\n";
echo $xml->vcrSummary->vcr[0] ."\n";
echo "Min Price: " . $xml->vcrSummary->vcr[0]['minPrice'] ."\n";
echo "\nVCR - 1\n";
echo $xml->vcrSummary->vcr[1] ."\n";
