    • getIgnoreWhitespaceOnlyTextNodeFactory

      public static NodeFactory getIgnoreWhitespaceOnlyTextNodeFactory()
      Returns a node factory that removes each
      invalid reference 
      nu.xom.Text
      node that is empty or consists of whitespace characters only (boundary whitespace). This method fully preserves narrative Text containing whitespace along with other characters.

      Otherwise this factory behaves just like the standard

      invalid reference 
      NodeFactory
      .

      Ignoring whitespace-only nodes reduces memory footprint for documents that are heavily pretty printed and indented, i.e. human-readable. Remember that without such a factory, every whitespace sequence occurring between element tags generates a mostly useless Text node.

      Finally, note that this method's whitespace pruning is appropriate for many, but not all XML use cases (round-tripping). For example, the blank between <p><strong>Hello</strong> <em>World!</em></p> will be removed, which might not be what you want. This is because this method does not look across multiple Text nodes.

      Returns:
      a node factory
