<A>
<b>
<c>
<col>val1<col>
<col>val2<col>
<col>val3<col>
</c>
<c>
<col>val7<col>
<col>val8<col>
</c>
</b>
<b>
<c>
<col>val10<col>
</c>
<c>
<col>val11<col>

From your previous post:

Post a test case: create table and insert statements along with the result you want with these data.

Before 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 align the columns in result.
Use the "Preview Message" button to verify.
Also always post your Oracle version (4 decimals).

Regards
Michel

Where is the test case?
And what did you try since your last questions?

Search here for xmlelement, extractvalue, xmlsequence, there are many examples.

Michel

Why "val10" and not "val1", "val2"...?
