Method Detail

getIgnoreWhitespaceOnlyTextNodeFactory

public static NodeFactory getIgnoreWhitespaceOnlyTextNodeFactory()

Returns a node factory that removes each 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 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
