//  where the name of the color ends in "e"

//  ---------------------------------------------------------------------------------
//  Now do the same, but instead use SearchForAttribute2
//  which updates the internal reference of the caller instead
//  of returning the found node.

// xBeginAfter is a Chilkat.Xml
$xBeginAfter = $xSearchRoot->GetSelf();
// xSearch is a Chilkat.Xml
$xSearch = $xSearchRoot->GetSelf();

$success = $xSearch->SearchForAttribute2($xBeginAfter,'fruit','color','*e');
while ($success == 1) {

    print $xSearch->content() . ': ' . $xSearch->getAttrValue('color') . "\n";

    //  Copy the internal references so that the next search
    //  begins after the found node.
    $xBeginAfter->CopyRef($xSearch);
    $xSearch->CopyRef($xSearchRoot);
