The best bet is to check the DTML Users Guide. Although it is a long hard stare. Check the Zope book as well for fundamentals.
Is this refering to an earlier item in the sequence?
<dmtl-in list> <dtml-if "_['sequence-index']==5">This is the fifth occurance</dtml-if> </dtml-in> Yes indeed.
Is it the same as _.sequence-item-5 ?
The above is not possible. Remember that _ has a dual function. It A) accesses namespace: _.string.find('stringname, 'findStringText') _ pushes the results of the method into namespace. _.int(string) and so on... _['some-name'] has NOTHING to do with namespace. It only prevents 'some' being subtracted by 'name', when you intend some-name to be only one object.
If I have a name clash (two Z SQL Method's return ID), how to I look up the stack of namespaces?
Dont use ID as good practice, since ID is the document ID. BUT you can return REQUEST['id'] which is the REQUEST variable and not necessarily the Zope object ID. If you have multiple ID used in a nested <dtml-in> the ID resulted is owned by its superior IN. Forinstance, I add an 'a' or 'b'to ID to show: <dtml-in methoda> <-- You will return an ID here--> <dtml-var ID> <dtml-in methodb> <-- You will return an another ID here--> <dtml-var ID> </dtml-in> <dtml-in> Now I a the result <dtml-in methoda> <-- You will return an ID here--> <dtml-var ID(a)> <dtml-in methodb> <-- You will return an another ID here--> <dtml-var ID(b)> </dtml-in> <dtml-in> AFIAK. Possibly not. If you want to look up namespace, simply put <dtml-var REQUEST> in the bottom of your page and you will see all.....

<dtml-var "sequence-item-5"> does not work because it syubtracts item from sequence and five from item. Instead use:
<dtml-var "_['sequence-item']-5">
Is this refering to an earlier item in the sequence? Is it the same as _.sequence-item-5 ? Is there a declaration of _ anywhere that I can look at? If I have a name clash (two Z SQL Method's return ID), how to I look up the stack of namespaces? Yours in abject confusion, J. Cone
