Automated XML - Placeholder Structure Question

Question

I'm testing XML import for a series of publications that need use automated layouts...having never attemped this. But I am confounded regarding the placeholder structure and how it should mirror the XML structure and am banging my head against a wall.
The basics of my pub are: I have profiles for every school in a district. Profiles are grouped by type of school (elem, middle, high). So my test XML example is structured like this:
<elementarySchools>
<schoolData>
     <name>
     <address>
     <city>
     <state>
     etcetera...the rest of the profile is demographics, testing scores and other stuff.
</schoolData>
</elementarySchools>
Each school has about 43 fields.
I setup a document (not a tempate) with the 43 frames and taggge them to correspond to those in the XML
Each time I attempt the import to auto-populate, the XML comes in but no data displays in the frames.
QUESTION 1: Do the 43 frames need to be within a parent frame tagged as schoolData? If I drag a "schoolData" node in, it contains all of the proper data. But the objective is to auto-populate frames so they can be moved and styled as needed.
QUESTION: 2: If I ultimately need data to be displayed in a table-like layout, should I be trying to build tagge table layout?
I've read some tutorials on Adobe and I've watched a couple of Lynda vids, but I seems to be missing something important here. Any pointing in the right direction is appreciated.

Answer 1

Circling back on this in hopes someone can help get my ship pointed in a decent direction.
Reading up on tables via XML, as Mike mentioned, not the the greatest method and required building every table in the XML file. That's not really any more efficient for me.
However, since my "table" layout isn't that complex, I could create it using text frames that look like tables when styled correctly. This bring me back to my original issue: How do I get the XML to auto-populate tagged data frames and clone?
As sample layout would be something like this per page. Each "data" element would be a tagged frame, as well as School Name/address/phone/type:
--------------------beginning of school profile <schoolData> xml tag-----------------------
School name
school address • phone • type
Heading                                    Heading                  Heading
title | data                                   data                         data
title | data   
title | data   
title | data   
Heading                                 Heading
title | data                                title | data
title | data                                title | data
title | data                                title | data
title | data                                title | data
------------------ end of school  profile </schoolData> xml tag--------------------------------
--------------------beginning of school profile <schoolData> xml tag-----------------------
School name
school address • phone • type
Heading                                    Heading                  Heading
title | data                                   data                         data
title | data   
title | data   
title | data   
Heading                                 Heading
title | data                                title | data
title | data                                title | data
title | data                                title | data
title | data                                title | data
------------------ end of school  profile </schoolData> xml tag--------------------------------
>> Repeat through all profiles
I can create my layout using frames. All headings and titles can be built into a master page or template. I could set up individual frames for each data point. But I cannot for the life of me get the XML data to auto populate those tagged frames. It still seems to have something to do with the container nodes...that more than one text frame can be nested in another or tables have to be created in the XML...both of which kill the efficiency of using XML.
