PHP - Need Help With Simplexml To Check If Node Has Attributes

How can I print the attributes of a child node?
I have been trying and looking and cant get it.
I need the attributes of subfield printed after datafield
so a line would look like
datafield plus attributes plus subfield attributes plus subfield

=906 __$a0$bcbc$corignew etc...

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:
Code: [Select]
   <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:
Code: [Select]
   <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>

how can i check if i have PHP SimpleXML on the opensuse

is there a command that i can use in terminal

Hello
I have xml like this.

<?xml version="1.0" encoding="utf-8"?>
<data>
   <item ID="30001">
      <Company>Navarro Corp.</Company>
   </item>
   <item ID="30002">
      <Company>Performant Systems</Company>
   </item>
   <item ID="30003">
      <Company>Digital Showcase</Company>
   </item>
</data>


All i need to do is get any one of the  whole node from starting item tag to ending item tag from the xml, for example.  getting

<item ID="30002">
      <Company>Performant Systems</Company> 
   </item>

from whole xml file.

Can this be achieved using  SimpleXML object from PHP? if not how it can be done.


Thanks in advance

Can someone please explain to me what's the importance of node order? Does certain nodes that appear first or last have impact on traversing time?

Any suggestions much appreciated!
