Hey all, I have this SimpleXMLElement object with a XML setup similar to the following...

$xml <<< EOX
<books>
    <book>
        <name>ABCD</name>
    </book>
</books>
EOX;

$sx = new SimpleXMLElement( $xml );

Now I have a class named Book that contains info. about each book. The same class can also spit out the book info. in XML format akin the the above (the nested block).. example,

$book = new Book( 'EFGH' );
$book->genXML();

... will generate
<book>
    <name>EFGH</name>
</book>

Now I'm trying to figure out a way by which I can use this generated XML block and append as a child of so that now it looks like... for example..

// Non-existent member method. For illustration purposes only.
$sx->addXMLChild( $book->genXML() );    

...XML tree now looks like:
<books>
    <book>
        <name>ABCD</name>
    </book>
    <book>
        <name>EFGH</name>
    </book>
</books>

From what documentation I have read on SimpleXMLElement, addChild() won't get this done for you as it doesn't support XML data as tag value.

Any ideas on how I should go about this ?

Thanks, m^e
