WB_XML_LOAD need more description

Question

Hi,
I am many years experienced wiht Pl/SQL, but very poor about XML and all taht related stuff inside Oracle.
I have DB = 10.2.0.2 on AIX and OWB 10.2.0.1
I want to load an XML-file finally into 1 or more relational tables.
When I try to learn about wb_xml_load, I miss a lot of more practical descriptions.
the sample shows only XLS as target !
Where can I find detail information about the 'control_file' mentioned in wb_xml_load docu ?
Docu says: For more information on control files, see the Oracle Warehouse Builder User's Guide.
That's a really bad joke ! the docu is allready from that guide, but no details for how to build and use that control_file !!!
I need to learn how to use wb_xml_load for an Oracle-table as target.
Can I derive the structure of the target tables from registered schema ?
That is pretty weird, because it seems to be nested over several levels.
In the docu-sample: what menas the first element:
wb_xml_load('<OWBXMLRuntime>'
Can I use any name ? Does it have to match the first XML-file-element ?
please help with any tip, thanks LaoDe

Hi
Please follow below steps to load xml file to oracle database.
1.First connect to owb (Design Center) through your repository owner user (ex : REP_OWNER).
2. Import WB_XML_LOAD procedure . and exit to repository owner.
3. connect to owb design center through your repository user (ex : REP_USER)
Create New mapping and drag one Constant Operator and create one attribute, paste / edit following code
'<OWBXMLRuntime>'||
'<XMLSource>'||
'<file>E:\SOURCE\emp.xml</file>'||
'</XMLSource>'||
'<targets>'||
'<target truncateFirst = "FALSE" dateFormat="yyyy.MM.dd">rep_user.emp</target>'||
'</targets>'||
'</OWBXMLRuntime>'
4. Drag pre mapping operator and select WB_XML_LOAD procedure
5. Connect Constant Operator attribute to pre mapping operator.
6. Drag two dummy tables and connect source to target. (ex : drag t1 (table) tab two times and connect.
7. Validate and deploy the mapping.
8. grant necessary grant command to rep_owner user to rep_user user.
(Note : target truncateFirst = "FALSE" by default truncate the table. So you have to give grant privileges
To rep_user , select ,insert, delete privileges.
9. Execute the mapping , and check EMP table. (Note : before loading EMP table delete all records ).
