[docbook-apps] question on XML to XML transformation

Hi All,
 
I need to reformat the Docbook XML files to generate another XML output with the following tags:
 
<Computer>, </Computer>
<Heading-2>, </Heading-2>
<Heading-1>, </Heading-1>
<Heading-4>, </Heading-4>
<Indent-Comp>, </Indent-Comp>
<Indent-Para>, </Indent-Para>
<Note>, </Note>
<Num-Bullet>, </Num-Bullet>
<Num1-Bullet>, </Num1-Bullet>
<Para>, </Para>
<Para-Comp>, </Para-Comp>
<Para-Column>, </Para-Column>
<Round-Bullet>,</Round-Bullet>
<Round-BulletList>,</Round-BulletList>
 
Thanks & Regards,
Sarah
