Method Detail

getPath

public java.lang.String getPath(Element context)

Description copied from interface: Node

Returns the relative XPath expression which will return a node set containing the given node such as a/b/@c. No indexing will be used to restrict the path if multiple elements with the same name occur on the path.

Specified by:

getPath in interface Node

Parameters:

context - is the parent context from which the relative path should start. If the context is null or the context is not an ancestor of this node then the path will be absolute and start from the document and so begin with the '/' character.

Returns:

the XPath expression relative to the given context which will return a nodeset containing at least this node.

getUniquePath

public java.lang.String getUniquePath(Element context)

Description copied from interface: Node

Returns the relative unique XPath expression from the given context which will return a nodeset of one node which is the current node. This method will use the XPath index operator to restrict the path if multiple elements with the same name occur on the path.

Specified by:

getUniquePath in interface Node

Parameters:

context - is the parent context from which the path should start. If the context is null or the context is not an ancestor of this node then the path will start from the document and so begin with the '/' character.

Returns:

the XPath expression relative to the given context which will return a nodeset containing just this node.

appendText

public void appendText(java.lang.String text)

Description copied from interface: CharacterData

Appends the given text to this nodes text value. Calling this method is equivalent of the code node.setText(node.getText() + text) but allows for possible implementation optimisations (such as a text based node storing a StringBuffer internally

Specified by:

appendText in interface CharacterData

Parameters:

text - the text to append
