Lab 2 - Add Attribute

In this folder you will find planets.xml  Open it up to see its contents.
It contains data about planets. Note the default namespace declaration.

You are to change each <planet> element by deleting its child <name> element
and using it as the value of an id attribute, e.g., change this:

<planet>
    <name>Mercury</name>
    <description>...</description>
    ...
</planet>

to this:

<planet id="Mercury">
    <description>...</description>
    ...
</planet>
