Object Orientation in arrays

hello scripters
Just wondering what scripters feel like about a few possible uses of
arrays as objects...
Way back in HyperCard, where no arrays existed, we did the good old
approach
repeat with x = ...
get item x of anything
do "put it into object" & X
Thanks to Scott Raney, we can use arrays today...
But this leads to possible chaos...
For easy cases, pArray[x]...
For specific cases, pArray[thisobject]
BUT, it gets more complicated... Im working on a port of XUL, xml, Css,
and
a few more things into an ajax paradigm... As you can imagine, the xul
elements
are a bit more involved, some with "inherited" behaviors which in Rev are
actual
properties or extra commands...
So, in the end we get xulObjDB["object", ObjID, "property", "Hidden"]...
The problem is that transcript is not that good with multiarray
management...
For example you can't extract just a list of the objIDs... Not without a
loop,
the split function will not get you the 2nd column...
There's no way to create the Array without inserting each element into
it's
corresponding node. Not that wrappers can't be done but it's quite
inneficient.
I still have to read on transpose and other array styles (numeric) to see
if
there is any other way to do this via indexed/hashed arrays...
For example:
XULObjs[objID, "name"]
XULObjs[objID, "Type"]
or, in this case where it is easy to get a list of the ids...
XUL[ObjID] = object ID
XULName[ObjID] = name
XUProps[ObjID] = props, etc...
The issues here is that either we have one big array with LOTs of keys or
different arrays to parse each (less keys, but more loops )...
Any ideas on how to make big multidimensional arrays easier to handle?
So, im looking forward to your ideas on which is best given that there's a
tree hierarchy of objects in a xul or xml or html document to be parsed,
each object in the tree nodes has properties, possibly children objects...
And yes, there's possibly hundreds or thousands of objects...
I know how to handle these, that's not the problem. Im wondering if there
isn't
a better way to handle the arrays and/or which is easier to manage...
Thanks in advance
cheers
