Howdy,

I have an PHP page that edits XML files. I want ADD a new *id* attribute to all nodes on the page that do not have it all ready. Then i want to delete all of the values of *id* and set them as an incremental 1-x values down the page.

This is the current code i am using to edit specific nodes. Im trying to use DOM, but it doesn't have to be. I just need it to work.

 
<?php
$content = $_POST['content'];
$id = $_POST['id'];
$node = $_POST['node'];
$explode = explode("_",$node);
 
$dom=new DOMDocument();
$dom->load('sample.xml');
$dom->formatOutput = true;
//echo $dom->saveXML(); // show before file
$allnodes = $dom->getElementsByTagName($explode[0]);
foreach ($allnodes as $nodes) {
    if ($nodes->nodeName==$explode[0] and $nodes->getAttribute('id')==$id) { //
        $nodes->setAttribute($explode[1],$content);
    }
}
$dom->save('sample.xml');
?>

This is the XML file im working with. **NOTE** the missing *id* attributes of the 2nd *child01* node.

 
<?xml version="1.0" encoding="utf-8"?>
<parent option01="other info" option02="other info" id="1">
    <child01 option01="child01 option01" option02="child01 option02" id="2">

PHP people say this is belongs more in XML. I had posted this to the PHP forum with no response.

Ok, but as you are asking about a PHP editor that creates the XML file

I have an PHP page that edits XML files

I would assume you are looking for some PHP code.

take a look at Thierry's code class in

http://www.webmaster-talk.com/php-fo...unce-make.html

I don't get it....

I want ADD a new *id* attribute to all nodes on the page that do not have it all ready

Until there, ok.

but...

Then i want to delete all of the values of *id* and set them as an incremental 1-x values down the page

So, you just added ID's where they where missing, and now you want to reset it to an arbitrary value ?
And you want every id's to be at the same value; namely the count of elements in the document ???
Or you just want to number them sequentially ?

Ok, if you just want to add id attributes to every nodes, and to have them numbered sequentially:

PHP Code:

$dom=new DOMDocument();
$dom->load('sample.xml');
$dom->formatOutput = true;
//echo $dom->saveXML(); // show before file
$allnodes = $dom->getElementsByTagName("*");
$maxId=1;
foreach ($allnodes as $node) {
    $node->setAttribute('id',$maxId);
    $maxId++;
}
$dom->save('sample.xml');
echo $dom->saveXML(); 


tripy -

thanks for your suggestion. i guess what i meaning to do is add an *id* attribute to those nodes that dont have one. then when i add a new node, i want to be able top re-number them done the page.

chrishirst - thanks for Thierry's link.

Then no need to add and then remove.
You start at 1, and you re-set on each elements.

Those who don't have an id will get one, those with an id will have their value refreshed.

Right, tripy's code should work. I have to note that you don't want to add the attribute to all Nodes, but all Elements.
