I think Merant used to have a driver that did this, but I'm not sure if
it's available any more.
Note that there are a number of strategies for doing this. (Both SQL
Server and Oracle support this with SQL functions/operators.)
1) Document is table. The document must have the form:
<table>
<row>
<column1>...</column1>
<column3>...</column2>
...
<column_n>...</column_n>
</row>
...
<row>
...
</row>
</table>
This is simple, but the disadvantage is that it only works with
documents that match the above format.
2) Designate row elements. The user specifies a "row" element with an
XPath expression. The attributes and/or simple child elements of the
"row" element are treated as columns. This allows users to extract a
fixed part of any XML document.
3) Designate row and column elements. Same as (2), except that further
XPath expressions that use the row element as context designate the
column elements/attributes.
