Method Detail
-
getNodeType
public short getNodeType()
Description copied from interface:Node
Returns the code according to the type of node. This makes processing nodes polymorphically much easier as the switch statement can be used instead of multiple if (instanceof) statements.- Specified by:
getNodeType
in interfaceNode
- Overrides:
getNodeType
in classAbstractNode
- Returns:
- a W3C DOM complient code for the node type such as ELEMENT_NODE or ATTRIBUTE_NODE
-
getPath
public 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 interfaceNode
- 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 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 interfaceNode
- 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.
-
getStringValue
public String getStringValue()
Description copied from interface:Node
Returns the XPath string-value of this node. The behaviour of this method is defined in the XPath specification .- Specified by:
getStringValue
in interfaceNode
- Overrides:
getStringValue
in classAbstractNode
- Returns:
- the text from all the child Text and Element nodes appended together.
-
asXML
public String asXML()
Description copied from interface:Node
asXML
returns the textual XML representation of this node.
-
write
public void write(Writer writer) throws IOException
Description copied from interface:Node
write
writes this node as the default XML notation for this node. If you wish to control the XML output (such as for pretty printing, changing the indentation policy etc.) then please useXMLWriter
or its derivations.- Specified by:
write
in interfaceNode
- Overrides:
write
in classAbstractNode
- Parameters:
writer
- is theWriter
to output the XML to- Throws:
IOException
