DOM XML Issue

[xclntdesign]

I've been working on a script to open an XML file, insert a node, then save the file again.

 

$url = '../v3flashslideshow/slideshow_data0.xml';
$xml = new DomDocument();
$xml->formatOutput = true;
$xml->preserveWhitespace = false;
$xml->load($url);
$xpath = new DOMXPath($xml);

$first = $xpath->query('//galleries/gallery/img')->item(0);

// create node
$new = $xml->createElement("img");
$xml->appendChild($new);
$image = $xml->createAttribute("src");
$new->appendChild($image);
$new->setAttribute("src", $_GET['image']);

$first->parentNode->insertBefore($new, $first);

echo $xml->save($url);

 

The above code works except for the fact that it adds the new node twice.

 

When I change the last line to:

 

echo $xml->saveXML(); 

 

to display the code on the screen, it works fine, with the new node added only once.

 

I've tried many different work arounds, and nothing seems to work.

 

Anyone have any ideas?

 

Thanks in advance.

hmm strange...

 

i personally add the node to the dom after creating and populating it.

 

try this and let us know what happens...

 

$new = $xml->createElement("img");

$image = $xml->createAttribute("src");

$new->appendChild($image);

$new->setAttribute("src", $_GET['image']);

$xml->appendChild($new);

Wow!  You made it seem so simple.

 

That indeed did the trick.  I think that was the one variation I didn't try.

 

Thanks!

I may be misreading but one more littel tweak

 

$new = $xml->createElement("img");

$image = $xml->createAttribute("src");

$new->appendChild($image);

$new->setAttribute("src", $_GET['image']);

$xml->appendChild($new);

 

you create the src attribute on the $image object but set it on the $new(node) object...

 

should it not be

 

$new = $xml->createElement("img");

$image = $xml->createAttribute("src");

$image->setAttribute("src", $_GET['image']);

$new->appendChild($image);

$xml->appendChild($new);
