org.jdom.Content

org.jdom.Text

All Implemented Interfaces:

Serializable, Cloneable

Direct Known Subclasses:

CDATA

public class Text
extends Content

Character-based XML content. Provides a modular, parentable method of representing text. Text makes no guarantees about the underlying textual representation of character data, but does expose that data as a Java String.

Constructor Detail

Text

protected Text()

This is the protected, no-args constructor standard in all JDOM classes. It allows subclassers to get a raw instance with no initialization.

Text

public Text(String str)

This constructor creates a new Text node, with the supplied string value as it's character content.

Parameters:

str - the node's character content.

Throws:

IllegalDataException - if str contains an illegal character such as a vertical tab (as determined by Verifier.checkCharacterData(java.lang.String))

Method Detail

getText

public String getText()

This returns the value of this Text node as a Java String.

Returns:

String - character content of this node.

getTextTrim

public String getTextTrim()

This returns the textual content with all surrounding whitespace removed. If only whitespace exists, the empty string is returned.

Returns:

trimmed text content or empty string

getTextNormalize

public String getTextNormalize()

This returns the textual content with all surrounding whitespace removed and internal whitespace normalized to a single space. If only whitespace exists, the empty string is returned.

Returns:

normalized text content or empty string

normalizeString

public static String normalizeString(String str)

This returns a new string with all surrounding whitespace removed and internal whitespace normalized to a single space. If only whitespace exists, the empty string is returned.

Per XML 1.0 Production 3 whitespace includes: #x20, #x9, #xD, #xA

Parameters:

str - string to be normalized.

Returns:

normalized string or empty string

setText

public Text setText(String str)

This will set the value of this Text node.

Parameters:

str - value for node's content.

Returns:

the object on which the method was invoked

Throws:

IllegalDataException - if str contains an illegal character such as a vertical tab (as determined by Verifier.checkCharacterData(java.lang.String))

append

public void append(String str)

This will append character content to whatever content already exists within this Text node.

Parameters:

str - character content to append.

Throws:

IllegalDataException - if str contains an illegal character such as a vertical tab (as determined by Verifier.checkCharacterData(java.lang.String))

append

public void append(Text text)

This will append the content of another Text node to this node.

Parameters:

text - Text node to append.

getValue

public String getValue()

Returns the XPath 1.0 string value of this element, which is the text itself.

Specified by:

getValue in class Content

Returns:

the text

toString

public String toString()

This returns a String representation of the Text node, suitable for debugging. If the XML representation of the Text node is desired, either getText() or XMLOutputter.outputString(Text) should be used.

Overrides:

toString in class Object

Returns:

String - information about this node.

clone

public Object clone()

This will return a clone of this Text node, with the same character content, but no parent.

Overrides:

clone in class Content

Returns:

Text - cloned node.
