The first proof of a successful installation is that your web server doesn't throw any errors after restarting. To check if everything went smoothly, load the PHP test page in your browser. You should see a section similar to the following image:
Figure 6. DOM XML support is enabled
Check if these settings are present and enabled:
For libxml and libxslt, only the version number may be listed (instead of the enabled/disabled status); this indicates they are present on your server.
Congratulations! Your server is now prepared for server-side development using XML and XSL.
