However, we live in a world full of limitationa and memory issues put an upper bound on the size of documents one can manipulate in this manner and how quickly such manipulation can be done. > (On the other hand, if the document is transient, such as when it is > used to transport data from on database to another and your application > is simply an intermediary performing a transform, then best practices > are less clear.) I've been thinking about this for a while and the only good practice I can come up with for transiently constructed data is to use a DOM implementation that supports XPath to perform such operations with minimal code and still preserve document fidelity. Yet this practice would fail to handle large documents well. -- THINGS TO DO IF I BECOME AN EVIL OVERLORD #35 I will not grow a goatee. In the old days they made you look diabolic.
