How to dynamically iterate XML Element in Augeas

I would like to iterate all the child elements in the XML.

Is it possible to iterate dynamically ? In other words, I would like to check / edit all the nested elements without knowing the last element number.

For eg:

In the following "server-groups" element contains three server-group child element. I would like to iterate all the server-group element without knowing the counts. Right now It is three. So that I could access the last element. If I dont know the last element number, Is it possible to iterate ?

<server-groups>
    <server-group name="ServiceGroupOne" profile="full-ha">
        <system-properties>
            <property name="jboss.default.multicast.address" value="232.0.2.20" boot-time="true"/>
            <property name="modcluster.proxylist" value="192.168.79.77:7777" boot-time="true"/>
            <property name="modcluster.lbgroup" value="SearchGroupOne" boot-time="true"/>
        </system-properties>
    </server-group>
    <server-group name="ServiceGroupTwo" profile="full-ha">
        <system-properties>
            <property name="jboss.default.multicast.address" value="232.0.2.20" boot-time="true"/>
            <property name="modcluster.lbgroup" value="SearchGroupTwo" boot-time="true"/>
            <property name="modcluster.proxylist" value="192.168.79.77:7777" boot-time="true"/>
        </system-properties>
    </server-group>
    <server-group name="ServiceGroupThree" profile="full-ha">
        <system-properties>
            <property name="modcluster.lbgroup" value="CommonSearchGroup" boot-time="true"/>
            <property name="modcluster.proxylist" value="192.168.79.77:7777" boot-time="true"/>
            <property name="jboss.default.multicast.address" value="232.0.2.20" boot-time="true"/>
        </system-properties>
   </server-group>
</server-groups>

In Augeas, iterating can be done using setm:

  COMMAND
    setm - set the value of multiple nodes

  SYNOPSIS
    setm <BASE> <SUB> [<VALUE>]

  DESCRIPTION
    Set multiple nodes in one operation.  Find or create a node matching SUB
    by interpreting SUB as a  path expression relative to each node matching
    BASE. If SUB is '.', the nodes matching BASE will be modified.

  OPTIONS
     <BASE>    the base node
     <SUB>     the subtree relative to the base
     <VALUE>   the value for the nodes
