Excel to XML Conversion

Hi,
I want to convert Excel to XML which should include text as well as images, shapes ect.
There is any way we can get openxml (Office Open XML) using POI API ?

I can able to get xml using Save As option with type "XML Spreadsheet 2003". But its only help to transform text where I m interested in images or at least its location.

Can any one guide?

Thanks.
