I think the way I'd approach this is to add numbers to the keys while
building the array, something like:
repeat for each parargraph P in tPage -- obviously, I don't know how
you're parsing the wiki text!
add 1 to count
put extractParagraph(P) into tArray[count & comma & extractHeadng(P)]
end repeat
then:
put keys(tArray) into tKeys
sort lines of tKeys numeric by item 1 of each
repeat for each line K in tKeys
put item 2 to -1 of K into tHeading
put tArray[K] into tText
.....
end repeat
of course, with the new arrays,you could do something like:
repeat for each parargraph P in tPage
add 1 to count
put extractHeading(P) into tArray[n]["heading"]
put extractParagraph(P) into tArray[n]["text"]
end repeat
then:
repeat with n = 1 to the number of lines in keys(tArray)
get tArray[n]["heading"]
get tArray[n]["text"]
end repeat
Best,

Personally the returned keys being unordered has never been an
issue for
me.
Can you illustrate some situations where this is a problem?
In parsing data in order to layout in Rev I often use arrays.
However the
order of the original data is often important. Take a recent
example - I am
working on updating some scripts that parse wiki formatted text. I
want to
extract all the headers (like html headers they can be of different
levels)
and store the paragraph of html that goes with each section. Then I
want to
lay out the data in a Rev interface. I create an outline from the wiki
headers and when the user clicks on the header the corresponding
text is
displayed.
There are a number of ways of doing this - and if anyone has any
suggestions
about the best way please chip in - you can use list and Rev based
indexes,
you can use XML, or you can use arrays. XML is natural for these
hierarchical tree style data structures, but franksly a bit of a
pain and
overkill. So I tend to use arrays, and looking very much forward to
the
nested arrays in beta 3 for this.
However in order to "reconstruct" the original order of the document I
cannot simply loop through the keys of the array as the headers
will be all
out of order. So I have to go to the effort of storing both the
array and an
ordered index of the array. Then if I need to store this data and
have two
things and two places to store it.
In general about 1/3 of the time I use arrays I also have to store an
ordered index.
