how to correctly access an XML node ?

[jasonc]

Please can someone advise how I correctly access each of the nodes in an XML file.

 

echo($geoLocXML->isp . '<br>');

this is what I used before and it worked up to last month, then all of a sudden it failed.  I have also tried this code on a different server and it fails there too, so it suggests there is an error in the code, but for the life of me I can not find it.

 

 

 

<?php                //exit;

error_reporting(-1);

//$ip = $_SERVER['REMOTE_ADDR'];
//$geoLocXML = getGeoLocXML($ip); //->result[0];
//$geoLocXML = file_get_contents('http://api.geoiplookup.net/?query='.$ip);
$getGeoLocXML = simplexml_load_file('http://www.mysite.com/getGeoLocXML.xml');

/*
$getGeoLocXML = '<?xml version="1.0" encoding="iso-8859-1"?        >
<ip>
<results><result><ip>123.123.123.123</ip><host>123.123.123.123</host><isp>Provider</isp><city>My City</city><countrycode>GB</countrycode><countryname>United Kingdom</countryname><latitude>123.123</latitude><longitude>-1.123</longitude></result></results>
</ip>
';
*/

$geoLocXML = $getGeoLocXML->result[0];
echo($geoLocXML . '<br>');
echo($geoLocXML->isp . '<br>');
echo($geoLocXML[city] . '<br>');
echo($geoLocXML[countryname] . '<br>');

/*
<results>
<result>
<ip>123.123.123.123</ip>
<host>123.123.123.123</host>
<isp>Provider</isp>
<city>My City</city>
<countrycode>GB</countrycode>
<countryname>United Kingdom</countryname>
<latitude>123.123</latitude>
<longitude>-1.123</longitude>
</result>
</results>
*/
?>

 

 

<?xml version="1.0" encoding="iso-8859-1"?>

<ip>
<results><result><ip>123.123.123.123</ip><host>123.123.123.123</host><isp>Provider</isp><city>My City</city><countrycode>GB</countrycode><countryname>United Kingdom</countryname><latitude>123.123</latitude><longitude>-1.123</longitude></result></results>
</ip>

Use -> for nodes and [] for attributes (or indexes). So like the ISP value, and both use the arrow.

$geoLocXML = $getGeoLocXML->result[0];
echo($geoLocXML . '<br>');
echo($geoLocXML->isp . '<br>');
echo($geoLocXML->city . '<br>');
echo($geoLocXML->countryname . '<br>');
