  • Method Details

    • printRaw

      void printRaw(String s) throws IOException
      Send raw data to the stream. Mainly useful for things like DOCTYPE declarations. Use with care!
      Parameters:
      s - a string of data to include verbatim in the XML stream
      Throws:
      IOException

    • openTag

      void openTag(String nsURI, String localName) throws IOException
      Open a new namespace-qualified XML tag.
      Parameters:
      nsURI - A URI for the namespace to use
      localName - The name of the tag
      Throws:
      IOException

    • openTag

      void openTag(String name) throws IOException
      Open a new unqualified XML tag. This may also be used if you want to do namespace management yourself, independantly of the XMLWriter
      Parameters:
      name - The name of the tag.
      Throws:
      IOException

    • attribute

      void attribute(String nsURI, String localName, String value) throws IOException
      Add an attribute to an element. This will throw an exception if it's not called immediately after an openTag command.
      Parameters:
      nsURI - A URI for the namespace to use
      localName - The name of the attribute
      value - The textual value of the attribute
      Throws:
      IOException

    • attribute

      void attribute(String qName, String value) throws IOException
      Add an un-qualified attribute to an element. This will throw an exception if it's not called immediately after an openTag command.
      Parameters:
      qName - The name of the attribute to set
      value - The textual value of the attribute
      Throws:
      IOException

    • print

      void print(String data) throws IOException
      Prints some textual content in an element.
      Throws:
      IOException

    • println

      void println(String data) throws IOException
      Prints some textual content, terminated with a newline character.
      Throws:
      IOException

    • closeTag

      void closeTag(String nsURI, String qName) throws IOException
      Closes an element
      Parameters:
      nsURI - A URI for the namespace to use
      qName - The name of the tag
      Throws:
      IOException

    • closeTag

      void closeTag(String name) throws IOException
      Closes an un-qualified element.
      Parameters:
      name - The tag name
      Throws:
      IOException

    • declareNamespace

      void declareNamespace(String nsURI, String prefixHint) throws IOException
      Hints that a namespace is going to be used in a sub-tree. Use this method to avoid namespaces that are used only in leaf-nodes of a tree being re-defined every time they are used. The XMLWriter will generally try to use the suggested prefix for this namespace, but there is no guarentee of this. In particular, if the namespace is already in use, the current prefix will still be used. Similarly if the suggested prefix has already been used for another namespace, a new one will be auto-generated.
      Parameters:
      nsURI - The namespace to declare
      prefixHint - A suggested prefix-string for this namespace.
      Throws:
      IOException

    • close

      void close() throws IOException
      Close this XMLWriter, and it's underlying stream.
      Throws:
      IOException
