I have several xml files that are formated this way:

<ROOT>
  <OBJECT>
    <identity>
        <id>123</id>
    </identity>     
    <child2 attr = "aa">32</child2>
    <child3>
        <childOfChild3 att1="aaa" att2="bbb" att3="CCC">LN</childOfChild3>
    </child3>
    <child4>
        <child5>
            <child6>3ddf</child6>
            <child7>
                <childOfChild7 att31="RR">1231</childOfChild7>
            </child7>
        </child5>
    </child4>
  </OBJECT>
  <OBJECT>
    <identity>
        <id>124</id>
    </identity>     
    <child2 attr = "bb">212</child2>
    <child3>
        <childOfChild3 att1="ee" att2="ccc" att3="EREA">OP</childOfChild3>
    </child3>
    <child4>
        <child5>
            <child6>213r</child6>
            <child7>
                <childOfChild7 att31="EE">1233</childOfChild7>
            </child7>
        </child5>
    </child4>
  </OBJECT>
</ROOT>

How can i format it this way?:

<ROOT>
    <OBJECT>    
        <id>123</id>
        <child2>32</child2> 
        <attr>aa</attr>
        <child3></child3>
        <childOfChild3>LN</childOfChild3>
        <att1>aaa</att1>
        <att2>bbb</att2>
        <att3>CCC</att3>
        <child4></child4>
        <child5></child5>
        <child6>3ddf</child6>
        <child7></child7>
        <childOfChild7>1231</childOfChild7>
        <att31>RR</att31>
    </OBJECT>
        <OBJECT>    
        <id>124</id>
        <child2>212</child2>    
        <attr>bb</attr>
        <child3></child3>
        <childOfChild3>LN</childOfChild3>
        <att1>ee</att1>
        <att2>ccc</att2>
        <att3>EREA</att3>
        <child4></child4>
        <child5></child5>
        <child6>213r</child6>
        <child7></child7>
        <childOfChild7>1233</childOfChild7>
        <att31>EE</att31>
    </OBJECT>   
</ROOT>

I know some C# so maybe a parser there? or some generic xslt? The xml files are some data received from a client, so i can't control the way they are sending it to me.

L.E. Basically when i am trying to test this data in excel (for example i want to make sure that the attribute of childOfChild7 corresponds to the correct identity id) i am getting a lot of blank spaces. If i am importing in access to get only the data i want out, i have to do a thousands subqueries to get them all in a nice table. Basically i just want to see for one Object all its data (one object - One row) and then just delete/hide the columns i don't need.
