Editing XML Nodes through SimpleXML PHP

Question

I know similar questions have been asked several times, but I can't find a solution to the following: I've got a simple XML file: servers.xml ``` Google

http://www.google.com

Yahoo

http://www.yahoo.com

Bing

http://www.bing.com

``` Now, I'm trying to get the `` node which has a name of "Google" for example, and then change the address tag. I have no idea how to go about it using SimpleXML. So an example scenario would the following: - Get the server object/array where $serverName = "Google" - Edit the server's address field to something different like http://www.google.co.uk - Write the changes back to the XML file. Any help would be appreciated.

Accepted Answer

Get the server object/array where $serverName = "Google"

```
// An array of all <server> elements with the chosen name
$googles = $servers->xpath('server[name = " Google "]');
```

Edit the server's address field to something different like http://www.google.co.uk

```
//Find a google and change its address
$google->address = 'http://www.google.co.uk';
```

Write the changes back to the XML file.

```
$servers->saveXML('path/to/file.xml');
```

Full example

```
$servers = simplexml_load_file('path/to/file.xml');
$googles = $servers->xpath('server[name=" Google "]');
foreach ($googles as $google) {
    $google->address = 'http://www.google.co.uk';
}
$servers->saveXML('path/to/file.xml');
```
