Splitting of your data: Create on file for one instance of whatever data  
you have and read them. You could even create the semantic context of all  
those files by having something like

<data>
   <item/>
   <item/>
</data>
<continues in="next_file_name.xml">

You will know best how to spilt up your data to decrease file sizes and  
thus memory usage
