Question : adding constant value to numeric xml field

I have a large (1.4 MB) XML file with thousands of entries that need mathematical modification.  This is a one-time job so I don't need anything fancy.  Every decimal value in one field (x) needs to be increased by a constant decimal value (y).  So I am simply trying to add x+y then overwrite the existing value of x.  I tried importing it to Excel to make the changes, but it couldn't save as XML again.  Briefly looked at doing a search and replace in XML Editor 2007. Solution can use ColdFusion or PHP if needed.
