Hi, I'm a newbie, too, but this much I can tell you:  The colon (':') in 
a tag name is used to denote a namespace, so you're telling an XML 
parser that "system" contains an element "free" belonging to a namespace 
"cpu1" and another kind of "free" belonging to a namespace "cpu2".  If 
you look at it this way:
<getinfo>
  <orchard>
    <appletree:fruit>10</appletree:fruit>
    <orangetree:fruit>90</orangetree:fruit>
  </orchard>
</getinfo>

They're not the same things.

You could use this:
<getinfo>
  <system>
    <free cpu="1">10</free>
    <free cpu="2">90</free>
   </system>
</getinfo>

(in this case, you are using an attribute named "cpu")

or this:
<getinfo>
  <system>
    <cpu>
      <id>1</id>
      <free>10</free>
    </cpu>
    <cpu>
      <id>2</id>
      <free>90</free>
    </cpu>
  </system>
</getinfo>

There are probably other ways to do it, but I would prefer the last example.
