Basic question - querying xmltype column

Question

Hi,
Sorry for the basic question but please could someone paste in a working 'select where' statement which will pick out only those rows containing an element with specified content.
For example, how would I return n complete XML documents as query results for a situation where 'element_1' has text content 'apples'?
This does not seem to work:
SELECT x.xml_body.extract('/root_element/element_1/text()').getStringVal()
FROM xmltable x
WHERE x.xml_body.extract('/root_element/element_1/text()').getStringVal()='apples'

Answer 1

Hi Paul,
The query you have given works. I tried that query in the following format and it works.
Query 1:
SELECT x.xmlcol.extract(/Employee/Name/text()').getStringVal()
FROM table_name x
WHERE x.xmlcol.extract('/Employee/Name/text()').getStringVal()='Anu'
Query 2:
SELECT extractvalue(x.xmlcol,'//Name/text()')
FROM table_name x
WHERE extractvalue(x.xmlcol,'//Name/text()')='Srini'
Both the queries work. The xml is of the following format
<Employee company="Oracle">
<Name>Anu</Name>
<Department>OTN</Department>
<Location>India</Location>
</Employee>
Can you please tell the database version on which you are working?
