I'm trying to write a DTMLMethod which will write out a list of data items found from a catalog, sorted in alphabetical order. This is easy. Basically I do something like this:
<dtml-in "Catalog(meta_type='foo')" sort=someAttribute> <dtml-with "Catalog.getobject(data_record_id_)"> <dtml-var objvar1><dtml-var objvar2> ... </dtml-with> </dtml-in>
I've got this working, no problem. Now, since the list of these items might be somewhat long, I want to build a simple index at the top of the page and use page anchors to get to key points on the page. Basically I'm going to display the alphabet and when the user clicks on a letter, the page should scroll somewhere in the vicinity of an item which starts with that letter. To that end, what I would like to do is have some code inside of my dtml-in loop which gets the first letter from the current entry, checks to see if an anchor for that letter has been written, if not, a new anchor tag is inserted into the stream. My problem is I don't really know how to code this up. It seems like maybe that at least some of this should be done at the Python level but I'm not quite sure how to split up the functionality.
Has anybody done anything similar who would be willing to give me some advice as to the best way to go about solving this problem?
