s provide applications the ability to examine nodes as they are being serialized and decide what nodes should be serialized or not. The
interface is based on the
interface defined in [DOM Level 2 Traversal and Range
Entity , and children of
Attr nodes are not passed to the filter. The child nodes of an
EntityReference node are only passed to the filter if the
EntityReference node is skipped by the method
When serializing an
Element, the element is passed to the filter before any of its attributes are passed to the filter. Namespace declaration attributes, and default attributes (except in the case when " discard-default-content" is set to
false), are never passed to the filter.
The result of any attempt to modify a node passed to a
LSSerializerFilter is implementation dependent.
DOM applications must not raise exceptions in a filter. The effect of throwing exceptions from a filter is DOM implementation dependent.
For efficiency, a node passed to the filter may not be the same as the one that is actually in the tree. And the actual node (node object identity) may be reused during the process of filtering and serializing a document.
