A more complete program would create an output file and have better error reporting. It
would also have more lines of the poem than I can remember.

Program: xml2mif
Adobe FrameMaker [ 58 ] uses an interchange language called MIF (Maker Interchange
Format), which is vaguely related to XML but is not well-formed. Let's look at a program
that uses DOM to read an entire document and generate code in MIF for each node. This pro-
gram was in fact used to create some chapters of the first edition.

The main program, shown in Example 20-16 , is called XmlForm ; it parses the XML and calls
one of several output generator classes. This could be used as a basis for generating other
formats.
