this is summary object structure:
<summary>
<vms>
<total></total>
<active></active>
</vms>
<hosts>
<total></total>
<active></active>
</hosts>
<users>
<total></total>
<active></active>
</users>
<storage_domains>
<total></total>
<active></active>
</storage_domains>
</summary>
you can access properties directly, like this:
summary.hosts.active
