As Dmitry says, it is difficult to guess what you want because your 
question is unclear.

But I recognize your use of elements and namespace prefixes as likely 
being OASIS UBL.

Looking at the TaxTotal aggregate (note the page is very long and 
takes a while to load):

http://docs.oasis-open.org/ubl/prd2-UBL-2.1/mod/summary/reports/UBL-AllDocuments-2.1.html#t-CommonLibrary-1820

... I see that <cbc:TaxAmount> is a mandatory child of 
<cac:TaxTotal>.  Therefore you know the count of those children is 
the same as the count of the parents.

But you cite <cbc:RoundingAmount> in your question.  Are you perhaps 
looking for the count of those <cac:TaxTotal> elements that have the 
optional <cbc:RoundingAmount> child?  That would be:

   count(cac:TaxTotal[cbc:RoundingAmount])

... which actually would be the same as the count of the rounding amounts:

   count(cac:TaxTotal/cbc:RoundingAmount)

I hope this helps ... but it is only a guess.
