Class HTMLdtd

java.lang.Object
org.apache.xml.serialize.HTMLdtd

public final class HTMLdtd extends Object
Deprecated.
This class was deprecated in Xerces 2.9.0. It is recommended that new applications use JAXP's Transformation API for XML (TrAX) for serializing HTML. See the Xerces documentation for more information.
Utility class for accessing information specific to HTML documents. The HTML DTD is expressed as three utility function groups. Two methods allow for checking whether an element requires an open tag on printing (isEmptyTag(java.lang.String)) or on parsing (isOptionalClosing(java.lang.String)).

Two other methods translate character references from name to value and from value to name. A small entities resource is loaded into memory the first time any of these methods is called for fast and efficient access.
