I have two tables

Table Name: Graph

UID1   UID2
----------- 
12     23 
12     32
41     51
32     41

Table Name: Profiles

NodeID UID  Name
-----------------
1      12   Robs
2      23   Jones
3      32   Lim
4      41   Teo
5      51   Zacks

I want to get an xml file like this:

<graph directed="0">
  <node id="1">
    <att name="UID"  value="12"/>
    <att name="Name" value="Robs"/>
  </node>
  <node id="2">
    <att name="UID" value="23"/>
    <att name="Name" value="Jones"/>
  </node>
  <node id="3">
    <att name="UID" value="32"/>
    <att name="Name" value="Lim"/>
  </node>
  <node id="4">
    <att name="UID" value="41"/>
    <att name="Name" value="Teo"/>
  </node>
  <node id="5">
    <att name="UID" value="51"/>
    <att name="Name" value="Zacks"/>
  </node>
  <edge source="12" target="23" /> 
  <edge source="12" target="32" /> 
  <edge source="41" target="51" /> 
  <edge source="32" target="41" /> 
</graph>

Thanks very much!
