Re example "poll" product: I want to insert a tag in a new page which will iterate through a number of created "polls"(id's are p1,p2,p3...), all of which exist in one folder and which will dynamically create a list of links. After reading the DTML User Guide I'm still unclear. The "in" tag seems the correct choice. However I can't seem to arrive at the correct syntax. Help appreciated. Also the "Company example in the "investors corner" of the Zope site gives this: <P>Please visit the following departments: <!--#tree--> <!--#if "id[0:5] == 'dept_'"--> <A HREF="<!--#var id-->"><!--#var title--></A> <!--#/if--> <!--#/tree--> which successfully, gives a neat list of links to subfolders which begin with "dept_" I wondered what the id[0:5] means?
