Creating the XML Content

Listing 12.2 shows a sample XML loan document that is valid according to the DTD in Listing 12.1. Because we created this sample XML loan document manually, we inten-tionally simplified our task by making the term of the loan short—three months. Given the principal, the term in months, and interest rate key loan criteria, we used the formulas presented previously to compute the derived values in the document, including the monthly payment amount and payment data points over the lifetime of the loan.
