How do I get parameter values for xsql:dml

Question

Hi -
If I have an xml file like:
<stuff>
<arecord>
<item1> some data </item1>
<item2> more data </item2>
</arecord>
... more arecords ...
</stuff>
and I want to run an xsql script against it sending every "arecord" to a stored procedure by:
<xsql:dml>
begin
my_package.do_something(a_parm, a_parm2)
end;
</xsql>
how do I get the values in the <item1> and <item2> tags for every record into a_parm and a_parm2 in the call to do_something?
Thanks in advance,
-- ST

You need to post your XML file to an XSQL page that uses the:
<xsql:insert-request>
action element. You'll need to provide an associated XSLT stylesheet to transform your XML input document into the canonical XML format for the target table.
Then, you'll get each <arecord> (transformed into <ROW>) inserted into the columns of the target table.
For example, if your file looks like:
<stuff>
<arecord>
<item1> some data </item1>
<item2> more data </item2>
</arecord>
... more arecords ...
</stuff>and your table looks like:
ITEM1 VARCHAR2
ITEM2 VARCHAR2Then you'll need to provide a stylesheet that transforms your XML input into the format:
<ROWSET>
<ROW>
<item1>some data</item1>
<item2>more data</item2>
</ROW>
</ROWSET>and then the data will be inserted.
If the target table is actually a view, then you can create an INSTEAD OF INSERT trigger on your view to do additional custom processing for each row.
My "Building Oracle XML Applications" book has examples of doing all of this.
