get elements from a XML file as variables

Hi am trying to get some entrys from a xml file:

[code]
<license>
<server_ip>some ip</server_ip>
<domain>some domain</domain>
<license_key>some license key</license_key>
<allowed>1000</allowed>
<used>1</used>
<expire>2100-12-31</expire>
<update>2014-12-31</update>
<check>1a1937f9e47ea3d1402749aae9a679c9</check>
</license>
[/code]

What I need is getting the entry’s in to variables that I can process with php to check license

[code]
$serverip = entry
$domain = entry
$license = entry
$expire = entry
$update = entry
$check = entry
[/code]

Some of the above is send to license server with CURL rest is just check in my config file.

Thanks in advance
