- All Superinterfaces:
NodeFilter
LSSerializerFilter
s provide applications the ability to
examine nodes as they are being serialized and decide what nodes should
be serialized or not. The LSSerializerFilter
interface is
based on the NodeFilter
interface defined in [DOM Level 2 Traversal and Range]
.
Document
, DocumentType
,
DocumentFragment
, Notation
, 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 LSParserFilter.acceptNode()
.
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.

Method Details
-
getWhatToShow
int getWhatToShow()Tells theLSSerializer
what types of nodes to show to the filter. If a node is not shown to the filter using this attribute, it is automatically serialized. SeeNodeFilter
for definition of the constants. The constantsSHOW_DOCUMENT
,SHOW_DOCUMENT_TYPE
,SHOW_DOCUMENT_FRAGMENT
,SHOW_NOTATION
, andSHOW_ENTITY
are meaningless here, such nodes will never be passed to aLSSerializerFilter
.
Unlike [DOM Level 2 Traversal and Range] , theSHOW_ATTRIBUTE
constant indicates that theAttr
nodes are shown and passed to the filter.
The constants used here are defined in [DOM Level 2 Traversal and Range] .
