I'm working through "Hands-On Oracle Database 10g Express Edition for Windows" and one of the exercises is loading XML data into a table. The XML file that I'm trying to load came with the book's CD but I'm getting an error when I try to load it.
The code is:

<?xml version="1.0"?>
<ROWSET>
 <ROW>
  <AP_NAME>owl</AP_NAME>
  <AP_DESCRIPTION>Track feeding habits of owls.</AP_DESCRIPTION>
  <AP_VERSION>1.3</AP_VERSION>
  <DB_ID>3</DB_ID>
 </ROW>
 <ROW>
  <AP_NAME>finch</AP_NAME>
  <AP_DESCRIPTION>Track migration habits of finches.</AP_DESCRIPTION>
  <AP_VERSION>1.1</AP_VERSION>
  <DB_ID>1</DB_ID>
 </ROW>
 <ROW>
  <AP_NAME>robin</AP_NAME>
  <AP_DESCRIPTION>Track population statistics of robins.</AP_DESCRIPTION>
  <AP_VERSION>1.0</AP_VERSION>
  <DB_ID>2</DB_ID>
 </ROW>
</ROWSET>


I don't see any problem with the formatting but obvious;y something is wrong. Any ideas?

Thanks

error? what error? I don't see any error.
Are we expected to be mind readers, too?

The XML looks fine - the problem must lie elsewhere. Please show (copy&paste from your screen) how you are loading the XML, along with the exact error.

What is wrong is the way you load it but as you didn't show us what you did this is the only answer you can have.

Load was via Oracle Application Express.
Utilities->Data Load/Unload->Load->Load XML Data->Select Table->Select File.
Click, click, click, click, XML Load Error.

Here is the table definition:
CREATE TABLE  "APPLICATIONS" 
   (	"AP_ID" NUMBER(3,0) NOT NULL ENABLE, 
	"AP_NAME" VARCHAR2(25) NOT NULL ENABLE, 
	"AP_DESCRIPTION" VARCHAR2(4000), 
	"AP_VERSION" VARCHAR2(25) DEFAULT '1.0', 
	"DB_ID" NUMBER(3,0) NOT NULL ENABLE, 
	 CONSTRAINT "PK_APPLICATIONS" PRIMARY KEY ("AP_ID") ENABLE, 
	 UNIQUE ("AP_NAME") ENABLE, 
	 CONSTRAINT "APPLICATIONS_FK_DB_ID" FOREIGN KEY ("DB_ID")
	  REFERENCES  "DATABASES" ("DB_ID") ENABLE
   )
/

CREATE OR REPLACE TRIGGER  "APPLICATIONS_TPK" 
BEFORE
insert on "APPLICATIONS"
for each row
begin
SELECT handsonxe06.ap_ids.nextval
INTO :new.ap_id
FROM dual;
end;
/
ALTER TRIGGER  "APPLICATIONS_TPK" ENABLE
/

"XML Load Error" doesn't convey any information - isn't there a more descriptive error text?

The XML-table mapping looks OK. Perhaps data constraints are being violated, but we cannot know for sure without the error details.

You're right, it doesn't convey any information but that's all there is. I also agree that it's most likely a constraint issue.
I think the best thing to do is to type in the 4 rows manually and get on with things. Smile
