Generate multiple alerts from one xml file

[bascouba]

Hello,

I'm new to zabbix and I find it very useful. I have a vulnerability scanner (OpenVAS) that is running and I would like to generate alerts from a generated xml file that follow this schema

<hosts>
  <host>
    <report>abcd123zyx</report>
    <hostname> siteA.org </hostname>
    <severity> 8 </severity>
  </host>
  <host>
    <report>abcd456zyx</report>
    <hostname> siteB.org </hostname>
    <severity> 7 </severity>
  </host>
</hosts>

I've seen the usecases for templates with items/triggers but I'm not sure this is the correct way to do what I want. As the XML file already contains the alerts I would like zabbix to show, I wonder if it was possible for zabbix to just check the file (for exemple everyday) and pops alert for each host that is in the file.

It doesn't matter if the host concerned by zabbix's alert is my scanner's server if I can just display the hostname in the alert's name.

I hope I made my problem clear enough.

Thank you in advance.

edit: I can also just create a text file with every hostname in each line without noticing the severity like following:
siteA.org
siteB.org
siteC.org

Hello again,

so I managed to make a count of the number of hosts that are vulnerables.
I figured out that I could use the XML XPath field in the preprocessing's section of the item I was just wondering if I can manage to create an alert for every <host>.
I used hosts/host/hostname hosts/host/report and hosts/host/severity XPaths and I don't know how can I used these values in my trigger's name. I read the doc about {ITEM.VALUE<1-9>} but I don't understand how it works with preprocessed items

Thank you for reading
