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

tagName
- The element tag name (upper case)- Returns:
- True if element is empty
-
isElementContent
Deprecated.Returns true if element is declared to have element content. Whitespaces appearing inside element content will be ignored, other text will simply report an error.- Parameters:
tagName
- The element tag name (upper case)- Returns:
- True if element content
-
isPreserveSpace
Deprecated.Returns true if element's textual contents preserves spaces. This only applies to PRE and TEXTAREA, all other HTML elements do not preserve space.- Parameters:
tagName
- The element tag name (upper case)- Returns:
- True if element's text content preserves spaces
-
isOptionalClosing
Deprecated.Returns true if element's closing tag is optional and need not exist. An error will not be reported for such elements if they are not closed. For example, LI is most often not closed.- Parameters:
tagName
- The element tag name (upper case)- Returns:
- True if closing tag implied
-
isOnlyOpening
Deprecated.Returns true if element's closing tag is generally not printed. For example, LI should not print the closing tag.- Parameters:
tagName
- The element tag name (upper case)- Returns:
- True if only opening tag should be printed
-
isClosing
Deprecated.Returns true if the opening of one element (tagName) implies the closing of another open element (openTag). For example, every opening LI will close the previously open LI, and every opening BODY will close the previously open HEAD.- Parameters:
tagName
- The newly opened elementopenTag
- The already opened element- Returns:
- True if closing tag closes opening tag
-

tagName
- The element's tag nameattrName
- The attribute's name
-

Deprecated.Returns true if the specified attribute is a boolean and should be printed without the value. This applies to attributes that are true if they exist, such as selected (OPTION/INPUT).- Parameters:
tagName
- The element's tag nameattrName
- The attribute's name
-
charFromName

name
- Name of character reference- Returns:
- Character code or EOF (-1)
-
fromChar
