Automatic maths multiple lines Powershell

Question

I have an xml file that resembles like below:

<rule id="110001" level="5">
   <if_sid>110000</if_sid>
    <field name="test1</field>
    <description>test1</description>
 </rule>

  <rule id="110001" level="5">
   <if_sid>110000</if_sid>
    <field name="model.name">test2</field>
    <description>test2</description>
 </rule>

  <rule id="110001" level="5">
   <if_sid>110000</if_sid>
    <field name="model.name">test3</field>
    <description>test3</description>
 </rule>

The value 110001 should be added by 1 on the line rule id each time. Is there a way to accomplish this in powershell? It should be like 110002,110003,110004 and so on.

Thanks in advance
