Hi:
 Thank you for all your help. 
Here is the sample XML:

The output PDF look has this:

1 This level should be displayed only if the
conditions are high and low.
A This level should be displayed only if the
conditions are high and deep.
2 This level should be displayed only if the
conditions are high and deep.

Now val1 and val 2 are high and deep. So the expected
output is: 

2 This level should be displayed only if the
conditions are high and deep.

However, instead of 2, it should be numbered 1 since
it is the first level.

Desired output on the PDF would be:

1. This level should be displayed only if the
conditions are high and deep.

Please let me know what my mistake is on this style
sheet. How can I filter the output as well as format
it correctly.
