XML using PHP SimpleXML to change some xml data into child node

[RCgua]

I am trying to use php to loop through an xml file and reorganize the data.  For example, if I have a xml file about books and the first xml sub tag under the <book> tag is "<type>" .  I would like to make the following tags (nodes?) as child nodes under the type tag.  For example, instead of this:

   <book>
        <type>nonFiction</type>
        <title>Advanced PHP Programming</title>
        <author>George Schlossnagle</author>
        <publisher>Developer Library</publisher>
        <category>1</category>
        <category>3</category>
   </book>
   <book>
        <type>Fiction</type>
        <title>My Novel</title>
        <author>Same Nagle</author>
        <publisher>Developer Library</publisher>
        <category>1</category>
        <category>3</category>
   </book>

I want to make the xml look like this:

   <book>
        <type>nonFiction
                <title>Advanced PHP Programming</title>
                <author>George Schlossnagle</author>
                <publisher>Developer Library</publisher>
                <category>1</category>
                <category>3</category>
        </type>
   </book>
   <book>
        <type>Fiction
             <title>My Novel</title>
             <author>Same Nagle</author>
             <publisher>Developer Library</publisher>
             <category>1</category>
             <category>3</category>
        </type>
   </book>
