Hi,
The following error message
"ORA-19025: EXTRACTVALUE returns value of only one node
Given XPath points to more than one node.
Action: Rewrite the query so that exactly one node is returned."
is displayed when trying to query. I'm using the following query to extract xml data from the table.

select EXTRACTVALUE(xml_file,
'emp/row/ename'
) ENAME
from test_clob1.

table creation--
CREATE TABLE test_clob1 (
id NUMBER(15)
, file_name VARCHAR2(1000)
, xml_file xmltype
, timestamp DATE
);

xmldata file--
<emp>
<row>
<empno>3</empno>
<ename>ra</ename>
</row>
<row>
<empno>9</empno>
<ename>a</ename>
</row>
<row>
<empno>6</empno>
<ename>r</ename>
</row>
</emp>.
Can you please help on this.

What do you want to get? One specific ename or all enames?

Please read OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code (See SQL Formatter) and use code tags.
Use the "Preview Message" button to verify.
Also always post your Oracle version (4 decimals).

Regards
Michel
