Extracting xmlsequence from another xmlsequance in SQL - sql

Question

I have small problem with xmlsequence. I am codding in PL-SQL (Oracle)
Let's say, my XML looks like this:
<Row name="Row1">
<Field name="Filed1">
<Value1>
</Value1>
</Field>
<Row name="Row2inRow1">
<Field name="Filed2">
<Value1>
</Value1>
</Field>
</Row>
<Row name="Row2inRow1">
<Field name="Filed2">
<Value1>
</Value1>
</Field>
</Row>
<Row name="Row1">
<Field name="Filed1">
<Value1>
</Value1>
</Field>
<Row name="Row2inRow1">
<Field name="Filed2">
<Value1>
</Value1>
</Field>
</Row>
<Row name="Row2inRow1">
<Field name="Filed2">
<Value1>
</Value1>
</Field>
</Row>
It has 2x same "Row1" which is multiplicated, what's more inside Row1 I have multiplicated "Row2inRow1".
The problem is, I would like to select values from Ro2InRow1 and from Row1, to concat them, the effect should be:
Value1 (from 1st Row1) || Value1 (from 1st Row2inRow1)
Value1(from 1st Row1) || Value1 (from 2nd Row2InRow1)
Value1 (from 2nd Row1) || Value1 (from 3rd Row2inRow1)
Value1(from 2nd Row1) || Value1 (from 4th Row2InRow1)
I've tried to code is somehow, but I can't force my query to work right:
declare
xml_data xmldata;
begin
for rec1 in(select extractvalue(value(x),'//Field[#name="Filed1"]/Value1') ValueOfField1,
from table(xmlsequence(extract(xml_data.data,'//Row[#name="Row1"]')))x )
loop
dbms_output.put_line('1 : '|| ValueOfField1);
for rec2 in(select extractvalue(value(x),'//Field[#name="Filed2"]/Value1') ValueOfField2,
from table(xmlsequence(extract(xml_data.data,'//Row[#name="Row2inRow1"]')))k ) --? What here!
loop
dbms_output.put_line('1 : '|| ValueOfField2);
end loop;
end loop;
end;
Any ideas ? :(
