  • Method Details

    • getNameCode

      public int getNameCode()
      Get the nameCode of the node. This is used to locate the name in the NamePool
      Specified by:
      getNameCode in interface NodeInfo
      Overrides:
      getNameCode in class NodeImpl
      See Also:
    • getStringValue

      public String getStringValue()
      Description copied from interface: NodeInfo
      Return the string value of the node. The interpretation of this depends on the type of node. For an element it is the accumulated character content of the element, including descendant elements.
      Specified by:
      getStringValue in interface NodeInfo
      Returns:
      the string value of the node
    • getNodeType

      public final short getNodeType()
      Description copied from interface: NodeInfo
      Return the type of node.
      Specified by:
      getNodeType in interface Node
      Specified by:
      getNodeType in interface NodeInfo
      Returns:
      one of the values Node.ELEMENT, Node.TEXT, Node.ATTRIBUTE, etc.
    • setLocation

      public void setLocation(String uri, int lineNumber)
      Set the system ID and line number
    • getSystemId

      public String getSystemId()
      Get the system ID for the entity containing this node.
      Specified by:
      getSystemId in interface NodeInfo
      Specified by:
      getSystemId in interface Source
      Specified by:
      getSystemId in interface SourceLocator
      Overrides:
      getSystemId in class NodeImpl
      Returns:
      the System Identifier of the entity in the source document containing the node, or null if not known. Note this is not the same as the base URI: the base URI can be modified by xml:base, but the system ID cannot.
    • getLineNumber

      public int getLineNumber()
      Get the line number of the node within its source entity
      Specified by:
      getLineNumber in interface NodeInfo
      Specified by:
      getLineNumber in interface SourceLocator
      Overrides:
      getLineNumber in class NodeImpl
      Returns:
      the line number of the node in its original source document; or -1 if not available
    • copy

      public void copy(Outputter out) throws TransformerException
      Copy this node to a given outputter
      Specified by:
      copy in interface NodeInfo
      Throws:
      TransformerException
    • getTarget

      public String getTarget()
      The target of this processing instruction. XML defines this as being the first token following the markup that begins the processing instruction.
      Specified by:
      getTarget in interface ProcessingInstruction
    • getData

      public String getData()
      The content of this processing instruction. This is from the first non white space character after the target to the character immediately preceding the ?> .
      Specified by:
      getData in interface ProcessingInstruction
      Overrides:
      getData in class AbstractNode
    • setData

      public void setData(String data) throws DOMException
      Set the content of this PI. Always fails.
      Specified by:
      setData in interface ProcessingInstruction
      Overrides:
      setData in class AbstractNode
      Throws:
      DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
