AbraCadaver, Thanks for the feedback. The reason I'm using sockets is the above statement generates this error that I have not been able to resolve. "Warning: simplexml_load_file(http://192.168.2.106/xmldata) [function.simplexml-load-file]: failed to open stream: HTTP request failed! <?xml version="1.0" encoding="ISO-8859-1"?> in C:\xampp\htdocs\xmltest2.php on line 2" I think it is related to the way this device implements http. bh, Thank you for your feedback. I've reviewed and tried many samples / tutorials and applied to this xml with no luck. For example the following xpath code does not yield the <value> for probe 1: <?php // Establish a port 80 connection $http = fsockopen("192.168.2.106",80); // Send a request to the server $req = "GET /xmldata HTTP/1.0\r\n"; $req .= "Host: 192.168.2.106\r\n"; $req .= "Connection: Close\r\n\r\n"; fputs($http, $req); // Output the request results while(!feof($http)) { $xmlstr .= fgets($http, 2048); } // Close the connection fclose($http); $xml = simplexml_load_string($xmlstr); $myValue = $xml->xpath('//Group[@ID="9"]/Probe[@ID="1"]/value'); echo $myValue[0];

Hi, I'm new to php and coding in general. I'm trying to parse xml from a remote device and access specific value data. Here is the xml: <?xml version="1.0" encoding="ISO-8859-1" ?> - <Device id="S10011" hb="1935"> <Group id="1" /> <Group id="2" /> <Group id="3" /> <Group id="4" /> <Group id="5" /> <Group id="6" /> <Group id="7" /> <Group id="8" /> - <Group id="9"> - <Probe id="99"> <Value>1.0</Value> </Probe> - <Probe id="1"> <Value>86.4</Value> </Probe> - <Probe id="2"> <Value>45.7</Value> </Probe> - <Probe id="3"> <Value>2.9</Value> </Probe> - <Probe id="4"> <Value>1.0</Value> </Probe> </Group> </Device> ----------------------- Here is my php code to read in the xml: <?php // Establish a port 80 connection $http = fsockopen("192.168.2.106",80); // Send a request to the server $req = "GET /xmldata HTTP/1.0\r\n"; $req .= "Host: 192.168.2.106\r\n"; $req .= "Connection: Close\r\n\r\n"; fputs($http, $req); // Output the request results while(!feof($http)) { $data .= fgets($http, 1024); } // Close the connection fclose($http); $xml = simplexml_load_string($data); print_r ($xml); ?> This yields the following data: SimpleXMLElement Object ( [@attributes] => Array ( [id] => S10011 [hb] => 117546 ) [Group] => Array ( [0] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 1 ) [0] => ) [1] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 2 ) [0] => ) [2] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 3 ) [0] => ) [3] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 4 ) [0] => ) [4] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 5 ) [0] => ) [5] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 6 ) [0] => ) [6] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 7 ) [0] => ) [7] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 8 ) [0] => ) [8] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 9 ) [Probe] => Array ( [0] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 99 ) [Value] => 1.0 ) [1] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 1 ) [Value] => 84.2 ) [2] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 2 ) [Value] => 44.1 ) [3] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 3 ) [Value] => 4.8 ) [4] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 4 ) [Value] => 1.0 ) ) ) ) ) I would like to display group 9 probe 1 value for example and I cannot get it to work. Any tips?
