XSL attribute?

I need help pulling a file name from an element name through an attribute. My media is listed under a media items section and then referenced in the text by an attribute. Is there any way of referencing an element from an attribute? 

My XML example


Media Section:
        <media_item identifier="medad59010005" category_type_code="3" file_type_code="gif">
            <media_name>Figure 2-1. </media_name>
            <access_name>ad59010005.gif</access_name>
    </media_item>

Text section

                    <instruction_content>
            <media_ref media_alias="medad59010005"/>
        </instruction_content>

I need the <access_name> in place of the <media_ref> tag




Thanks
Greg
