Text

public interface Text implements CharacterData
Known Indirect Subclasses

The Text interface inherits from CharacterData and represents the textual content (termed character data in XML) of an Element or Attr. If there is no markup inside an element's content, the text is contained in a single object implementing the Text interface that is the only child of the element. If there is markup, it is parsed into the information items (elements, comments, etc.) and Text nodes that form the list of children of the element.

When a document is first made available via the DOM, there is only one Text node for each block of text. Users may create adjacent Text nodes that represent the contents of a given element without any intervening markup, but should be aware that there is no way to represent the separations between these nodes in XML or HTML, so they will not (in general) persist between DOM editing sessions. The Node.normalize() method merges any such adjacent Text objects into a single node for each block of text.

No lexical check is done on the content of a Text node and, depending on its position in the document, some characters must be escaped during serialization using character references; e.g. the characters "<&" if the textual content is part of an element or of an attribute, the character sequence "]]>" when part of an element, the quotation mark character " or the apostrophe character ' when part of an attribute.

Public Method Summary

abstract String
getWholeText()
Returns all text of Text nodes logically-adjacent text nodes to this node, concatenated in document order.
abstract boolean
isElementContentWhitespace()
Returns whether this text node contains element content whitespace, often abusively called "ignorable whitespace".
abstract Text
replaceWholeText(String content)
Replaces the text of the current node and all logically-adjacent text nodes with the specified text.
abstract Text
splitText(int offset)
Breaks this node into two nodes at the specified offset, keeping both in the tree as siblings.
