Best way to data transfer between Database & XML & Display to end user

Question

Hi,
What is the best mothod to insert the data into tables from XML and viceversa. Also I need to display the data to the end user, with the provision to edit the data.
Thanks in advance

If you want to edit and store the data completely in XML then you could do the following:
1) Register the XML schema and specify a default table.
2) Connect to the XDB repository and store your documents using FTP or WebDAV. Make sure they reference the registered schema in the instance header. This should load the underlying XMLTYPE table you specified as the default table.
3) Connect to the repository with a WebDAV-aware XML editor.
And if you want to take this a little further, then you could also do the following:
4) Create a relational view on top of your XML table using code similar to below.
CREATE OR REPLACE VIEW "ACT_LIST" ("NAME", "CITE", "SORT", "JURISDICTION", "LOCATION") AS
SELECT
ExtractValue(OBJECT_VALUE, '/act/act_version/name[1]') Name
, ExtractValue(OBJECT_VALUE, '/act/act_version/cite[1]') Cite
, ExtractValue(OBJECT_VALUE, '/act/act_version/name[1]/@sort') Sort
, ExtractValue(OBJECT_VALUE, '/act/@juris') Jurisdiction
, b.ANY_PATH Location
FROM
ACTS a
, RESOURCE_VIEW b
WHERE
Ref(a) = ExtractValue(b.RES, '/Resource/XMLRef')
5) Put that into an application (e.g. APEX) as a report.
6) Link from the report to the XML editor and pass the location of the document in the repository. Or you can use an embedded WYSIWYG XML editor so that they edit the document inside the application and the whole thing is fairly seamless for the user.
Hope this helps.
