If no subfolders were neccesary (for example accessing index_html in
SubFolder instead of SubSubFolder1) , you could access an object
with a string variable holding its id like this :

<dtml-var "_[variablename]">

the subfolder stuff makes it a bit more tricky, if that too
would be dynamic, but you could probably use another
string-variable to hold path-info..

perhaps something like (untested):


<dtml-with "_[pathInfoVar]">
<dtml-var "_[variablename]">
</dtml-with>
