Method Details | [hide private]

### __new__(T, S, ...)

Returns: a new object with type S, a subtype of T
Overrides: object.__new__

### apply_templates(self, context, node)

Call this method to retrieve the result of applying templates to an element.

The return value is a list of elements or text strings that were generated by the XSLT processor.

### execute(self, context, self_node, input_node, output_parent)

Execute this extension element.

Subclasses must override this method. They may append elements to the `output_parent` element here, or set its text content. To this end, the `input_node` provides read-only access to the current node in the input document, and the `self_node` points to the extension element in the stylesheet.
