Help with Java to XML

Question

All I need to know is how to bold the tag <CompanyID> </CompanyID> OR the text within it (1001, in given sample).
Here's a sample line of the data.txt file I'm working with:
1001,"Fitzsimmons, Des Marteau, Beale and Nunn",109,"COD","Standard",,109,8/14/1998 8:50:02
Thanks in advance!
