<SERVER VER="0.9" URL="computersciencelaboratories.com/" HOME="0" AID="=">
<SD TITLE="A" FLAGS="" HOST="computersciencelaboratories.com">
<LINKSIN NUM="3"/>
</SD>
<SD>
<POPULARITY URL="computersciencelaboratories.com/" TEXT="4759525"/>
<REACH RANK="4682738"/>
<RANK DELTA="-704558"/>
</SD>
</SERVER>


$xml2 = simplexml_load_file("$feed2");
$result2 = $xml2->xpath(server/sd[2]/popularity/@text);

XML and XPath are case sensitive
The correct XPath would be

xpath(/SERVER/SD[2]/POPULARITY/@TEXT)

I am not sure about the PHP, I think you need quotes around the XPath

xpath("/SERVER/SD[2]/POPULARITY/@TEXT")

By the way, I am pretty uncertain about this
simplexml_load_file("$feed2")
I think it should be
simplexml_load_file($feed2)
otherwise the variable would be regarded as a string

I got this working!!!  But the XML is not complete.....
$string = <<<XML
<SD>
<POPULARITY URL="computersciencelaboratories.com/" TEXT="4759525"/>
<REACH RANK="4682738"/>
<RANK DELTA="-704558"/>
</SD>
XML;

$xml = simplexml_load_string($string);
foreach($xml->POPULARITY[0]->attributes() as $a => $b) {
    echo $a,'="',$b,"\"\n";
}

why did you leave the XPath path?
I don't know enough about php, but the line with POPULARITY[0] smells rotten

i left the xpath because i couldnt get it working and i was trying other examples.

I finally got it to work though :)

$xml->SD[1]->POPULARITY[0]->attributes()

Thanks so much for your help, i didnt know it was case sensitive.
