I have used the following code to grab the values

<?php
strings = file_get_contents("feed.xml");
$xml=simplexml_load_string($strings);

foreach ($xml as $place)
{
echo "Total : ".$place->TOTALOFOUND->TOTAL."<br />";
echo "address: ".$place->PLACE->ADDRESS."<br />";
echo "Name : ".$place->PLACE->NAME."<br />";
echo "post code: ".$place->PLACE->POSTCODE."<br />";
echo "Small image: ".$place->PLACE->CATIM->SMALL."<br />";
echo "Medium Image: ".$place->PLACE->CATIM->MEDIUM."<br />";
echo "Descripton: ".$place->PLACE->CATIM->DESCRIPTION."<br />";
echo "Office ID: ".$place->PLACE->ID."<br />";
echo "Cord Lat: ".$place->PLACE->DIST->LAT."<br />";
echo "Cord Long: ".$place->PLACE->DIST->LONG."<br />"."<br />";
}
?>

the problem is that although i have 3 records in the xml it shows only the first results. and at the beginning it gives the below error. Can some one please help me

Total :
address:
Name :
post code:

Notice: Trying to get property of non-object in C:\wamp\www\site\test.php on line 16

Answer 1

You have to look at the structure of the XML more closely and access the nodes in the appropriate way base on their hierarchy.

echo "Total : ".$xml->FOUND->TOTALOFOUND->TOTAL."<br />";
foreach ( $xml->FOUND->PLACE as $place )
{
  echo "address: ".$place->ADDRESS."<br />";
  echo "Name : ".$place->NAME."<br />";
  echo "post code: ".$place->POSTCODE."<br />";
  echo "Small image: ".$place->CATIM->SMALL."<br />";
  echo "Medium Image: ".$place->CATIM->MEDIUM."<br />";
  echo "Descripton: ".$place->CATIM->DESCRIPTION."<br />";
  echo "Office ID: ".$place->ID."<br />";
  echo "Cord Lat: ".$place->DIST->LAT."<br />";
  echo "Cord Long: ".$place->DIST->LONG."<br />"."<br />";
}

That's yet another example of why one should always name their PHP vars after the node they represent. This way, you won't get lost in your tree's hierarchy.

The root node is <SEARCH/>, therefore its PHP var should be $SEARCH. Also, please note the use of simplexml_load_file()

$SEARCH = simplexml_load_file('feed.xml');

echo "Total : ".$SEARCH->FOUND->TOTALOFOUND->TOTAL."<br />";

foreach ($SEARCH->FOUND->PLACE as $PLACE)
{
    echo "address: ".$PLACE->ADDRESS."<br />";
    // etc...
    echo "Cord Lat: ".$PLACE->DIST->LAT."<br />";
}
