[yes2000]

Hi All,

I am trying to create XML file has Testid and custom filed value using execSetResults.php
i did use that the following to create the test id
$dom = new DomDocument('1.0');
$Tests = $dom->appendChild($dom->createElement('Tests'));
$SingleTest = $Tests->appendChild($dom->createElement('SingleTest'));

$TestCaseID = $SingleTest->appendChild($dom->createElement('TestCaseID'));
$TestCaseID->appendChild
(
$dom->createTextNode($args->tc_id)
);

how can I export the custom filed value or test name value

Regards,

Abe
