Parsing Nested XML With PHP

Our monitoring service has an API that I am trying to parse the XML from. I checked out magicparser.com which seems to be able to output it correctly, but can't for the life of me figure out how to output what I need.

I'm fairly new to XML with PHP, but have been using PHP for over a decade.

Ant point in the right direction would be appreciated.

Attached is a snippet of the API output.

SimpleXML is your friend:

http://php.net/manual/en/function.simplexml-load-file.php

<?php
error_reporting(E_ALL);

$xml = simplexml_load_file("alerts.xml");

echo '<pre>';
print_r($xml);

echo $xml->items->client[0]->clientid;

This is what I have so far, which is perfect, but I need to show all of the information, not just for client[0].

Ray, can you expand on this with foreach()?

<?php
error_reporting(E_ALL);

$xml = simplexml_load_file("alerts.xml");

echo '<pre>';
//print_r($xml);

echo $xml->items->client[0]->clientid . " | ";
echo $xml->items->client[0]->name . " | ";
echo $xml->items->client[0]->site[0]->name . " | ";
echo $xml->items->client[0]->site[0]->workstations[0]->workstation[0]->name . " | ";
echo $xml->items->client[0]->site[0]->workstations[0]->workstation[0]->failed_checks->check[0]->description . ": ";
echo $xml->items->client[0]->site[0]->workstations[0]->workstation[0]->failed_checks->check[0]->formatted_output . " ";
echo "<a href=\"https://www.-website-here.us/api/?apikey=apikeyhere&service=clear_check&checkid=";
echo $xml->items->client[0]->site[0]->workstations[0]->workstation[0]->failed_checks->check[0]->checkid . "\">";
echo $xml->items->client[0]->site[0]->workstations[0]->workstation[0]->failed_checks->check[0]->checkid;
echo "</a>"

?>

Ray, I took what you had and was able to make things work.

Thanks!

Thanks for the points and thanks for using EE. Going forward, please feel free to share the points with others who offer good answers. The first post by Roads_Roads is also a valid way of looking at the issue.

And a small sidebar note. Lose the ?> close-PHP tag if at all possible. At least don't use it reflexively. There are a host of reasons to avoid it, and the Zend Coding Standard dis-recommends it. So if your script can work without it, make it standard practice to leave it out.

Best regards, ~Ray
