extracting link from elements content

[smarto59]

I'm using xml as an index for p2p system in local network. Each peer
accesses the xml file which is stored in the server through their web
browsers. Until know the peers can only view the shared objects
descriptions list using the xml file but how can I make a dynamic link
in the xml file for each object which is a combination of the IP of
the target host and the absolute path of the object in the host
machine?
For example:
<host>
<IP>212.23.33.188</IP>
<object>
<name>C:\sharedfiles\pic.jpg</name>
<size>22</size>
</object>
</host>
