It looks to me like you have not made provision for writing out the modified XML document. You have modified the DOM in memory but that will not change the disk file automatically. The tools used to write a DOM depend on the Java version and/or outside toolkit you are using.
IF you have Java 1.4 or 1.5 - look at the javax.xml.transform package.
Any XML tutorial will have example code.
