JAXP Serialization

Although DOM is a read-write API in memory, it's sorely lacking when it comes to moving its in-memory data structure back out onto a disk, a network socket, or some other stream. Eventually, this omission will be rectified in DOM3. In the meantime, you have the choice of using either implementation-specific serialization classes or JAXP. The implementation-specific serialization classes generally provide more customization and features, but JAXP is sufficient for basic uses.

JAXP doesn't include a serialization package, but you can hack basic output through the javax.xml.transform package by conveniently “forgetting” to install a transform. :-) The pattern is the same as parsing a document with JAXP. The basic steps are as ...
