xpath stuff

[blinks]

The following code is throwing up a "Cannot use object of type DOMElement as array" error on the $node[@ID >0] line

 

$fieldNodeList = $xpath->query("/name");
$fieldNodeList2 = $xpath->query("/name/affiliation");
$newString = "hello";
foreach($fieldNodeList as $node) {
if ($node[@ID > 0]) {
	$fieldNodeList2->nodeValue = $newString;
}	
}

 

What this is meant to do is change /name/affiliation if the attribute value of /name is greater than 0.

 

Any suggestions, please??

Got it figured out -

$fieldNodeList = $xpath->query("/name");
$fieldNodeList2 = $xpath->query("/name/affiliation");
$newString = "hello";

foreach($fieldNodeList as $node) {
                if ($node->getAttribute("ID") > "0") {
                                $fieldNodeList2->item(0)->nodeValue = $newString;
                }              
}

Are you sure that that really does what you want? With that code, only the first /name/affiliation node will have its value set to hello regardless of how many name elements there are.

 

Would it be right to assume that you wish to change the affiliation value for all of the name nodes having an @id greater then zero?

Hi salathe, you are right in supposing I want to change the affiliation for all name nodes having an @id greater than zero. And yes, this code does do what I want. There is a foreach loop before the code, which I didn't include.

 

There is only ever one affiliation per name, and as the code is for a one-off global update, it doesn't have to cater for future possibilities.

 

Thanks for your reply :-)
