I have the following XML phone book which has phone numbers beginning with 07 & 01 which I would like to replace with +447 & +441 respectively. Can anyone suggest an easy way of doing this please?

```
    <directory>
    <Entry>
      <Name>***Travis</Name>
      <extension>02089425943</extension>
   </Entry>

   <Entry>
      <Name>***Nina</Name>
      <extension>0177377106</extension>
   </Entry>

   <Entry>
  <Name>***Yusra</Name>
  <extension>07790400192</extension>
   </Entry>

   <Entry>
     <Name>***Raoul</Name>
     <extension>07818838683</extension>
    </Entry>
 </directory> <directory>
