Can I setup Dependent items for xml webpage to parse array of items?

[dsd7150]

Good day!

I've got a system status by getting xml page from remote host by web.page.get. This item is named "Status page". So, how to parse array of items to create three items with type Dependent item with Master Item - "Status page". Example of page (in fact it is more complicated):

<items>
    <item>
        <id>item#1</id>
        <value>1</queue>
    </item><item>
        <id>item#2</id>
        <value>4</queue>
    </item><item>
        <id>item#3</id>
        <value>6</queue>
    </item>
</items>

I need three items from that page to get their values and make trigger on it. I don't want to do it by scripts and trapper. I think Dependent Item must be the best solution for that.

The second question: sometime system removes one of item(s). I need to make trigger to notice administrator about it. I think I need to use no_data in trigger. I'm right?
