I am writing code to read a bunch of xml files which describe
pharmaceutical drugs. They have namespace references at the top of each
file that look like this:
<document xmlns:voc="http://www.hl7.org/v3/voc"; xmlns="urn:hl7-org:v3"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="urn:hl7-org:v3
http://www.fda.gov/oc/datacouncil/schemas/spl/spl.xsd";>
I am having a challenging time coming up with an xpath query that works
even after registering a namespace like this:
$xpath->registerNamespace("voc","http://www.hl7.org/v3/voc"; );
I am trying a query like this:
$qry = '//component' ;
$nodeList = $xpath->query($qry);
I can't seem to make it work. Could someone please advise?
thanks
Selwyn
The whole program looks like this:
$dom=new DOMDocument;
$dom->load('./828C40F4-5969-4254-9008-36AF15CC601B.xml') ;
$qry = '//component' ;
$nodeList = $xpath->query($qry);
header('Content-Type: text/plain');
foreach ($nodeList as $node)
{
echo $dom->saveXML($node) . "\r\n";
}
