Constructor Detail

DomCharacterData

public DomCharacterData(SgmlPage page,
                        java.lang.String data)

Creates an instance of DomCharacterData.

Parameters:

page - the Page that contains this element

data - the data string wrapped by this node

Method Detail

getData

public java.lang.String getData()

Gets the data character string for this character data node.

Specified by:

getData in interface org.w3c.dom.CharacterData

Returns:

the data character string

setData

public void setData(java.lang.String data)

Sets the data character string for this character data node.

Specified by:

setData in interface org.w3c.dom.CharacterData

Parameters:

data - the new data character string

setNodeValue

public void setNodeValue(java.lang.String newValue)

Sets the data character string to the new string.

Specified by:

setNodeValue in interface org.w3c.dom.Node

Parameters:

newValue - the new string of data

setTextContent

public void setTextContent(java.lang.String textContent)

Specified by:

setTextContent in interface org.w3c.dom.Node

Overrides:

setTextContent in class DomNode

getLength

public int getLength()

Returns the number of characters in the character data.

Specified by:

getLength in interface org.w3c.dom.CharacterData

Returns:

the number of characters

appendData

public void appendData(java.lang.String newData)

Appends a string to character data.

Specified by:

appendData in interface org.w3c.dom.CharacterData

Parameters:

newData - the string to be appended to the character data

deleteData

public void deleteData(int offset,
                       int count)

Deletes characters from character data.

Specified by:

deleteData in interface org.w3c.dom.CharacterData

Parameters:

offset - the position of the first character to be deleted (can't be less than zero)

count - the number of characters to be deleted, if less than zero leaves the first offset chars

insertData

public void insertData(int offset,
                       java.lang.String arg)

Inserts a string into character data.

Specified by:

insertData in interface org.w3c.dom.CharacterData

Parameters:

offset - the position within the first character at which the string is to be inserted

arg - the string to insert

replaceData

public void replaceData(int offset,
                        int count,
                        java.lang.String arg)

Replaces characters of character data with a string.

Specified by:

replaceData in interface org.w3c.dom.CharacterData

Parameters:

offset - the position within the first character at which the string is to be replaced

count - the number of characters to be replaced

arg - the string that replaces the count characters beginning at the character at offset

substringData

public java.lang.String substringData(int offset,
                                      int count)

Extracts a substring from character data.

Specified by:

substringData in interface org.w3c.dom.CharacterData

Parameters:

offset - the position of the first character to be extracted

count - the number of characters to be extracted

Returns:

a string that consists of the count characters of the character data starting from the character at position offset

getNodeValue

public java.lang.String getNodeValue()

Specified by:

getNodeValue in interface org.w3c.dom.Node

Overrides:

getNodeValue in class DomNode

Returns:

the string data held by this node

getCanonicalXPath

public java.lang.String getCanonicalXPath()

Returns the canonical XPath expression which identifies this node, for instance "/html/body/table[3]/tbody/tr[5]/td[2]/span/a[3]".

WARNING: This sort of automated XPath expression is often quite bad at identifying a node, as it is highly sensitive to changes in the DOM tree.

Overrides:

getCanonicalXPath in class DomNode

Returns:

the canonical XPath expression which identifies this node
