Hello,
Thanks for your replies. I do not know whether JDev could help us in this situation.
Oracle XML DB recomends Xpath functions with SQL to in/out of xml data.
Our environment is
SQL*Plus: Release 9.2.0.4.0
Oracle9i Enterprise Edition Release 9.2.0.4.0
OS Windows 2000
We registered XML schema in XML DB. We went through user_xml_tab_cols, user_tab_cols, user_type_attrs and user_types views in Oracle. I could not find the differentiation between elements and attributes in oracle data dictionary. How do I find ATTR_NAME in USER_TYPE_ATTRS as elements or attributes ?
Here is some additional info.
I registered the schema countries. It created a O-R table "countries224_TAB"
After insert of XML we have
VALUE(X)
<?xml version="1.0" encoding="WINDOWS-1252"?>
<countries>
<country countryCode="USA">
<countryName>United States Of America</countryName>
</country>
</countries>
<?xml version="1.0" encoding="WINDOWS-1252"?>
<countries>
<country countryCode="CAN">
<countryName>Canada</countryName>
VALUE(X)
</country>
</countries>
<?xml version="1.0" encoding="WINDOWS-1252"?>
<countries>
<country countryCode="UK">
<countryName>United Kingdom</countryName>
</country>
</countries>
Querying dictionary gives
1 SELECT TYPE_NAME , ATTR_NAME, ATTR_TYPE_NAME, LENGTH
2 FROM user_type_attrs
3 WHERE TYPE_NAME in ( 'CountryType221_T')
4* AND ( ( ATTR_TYPE_OWNER ) = USER Or ( ATTR_TYPE_OWNER is NULL ))
SQL> /
TYPE_NAME ATTR_NAME ATTR_TYPE_NAME LENGTH
CountryType221_T countryCode VARCHAR2 3
CountryType221_T countryName VARCHAR2 4000
We have countryCode as attribute countryName as elements in our XML DB.
How do we differentiate attribute/elements through dictionary views?
Do we able to generate Xpath queries of XML using JDev?
Thanks in advance.
