Class XSLTExtension

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

Overrides: object.__new__

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. If you pass elements_only=True, strings will be discarded from the result list. The option remove_blank_text=True will only discard strings that consist entirely of whitespace (e.g. formatting). These options do not apply to Elements, only to bare string results.

If you pass an Element as output_parent parameter, the result will instead be appended to the element (including attributes etc.) and the return value will be None. This is a safe way to generate content into the output document directly, without having to take care of special values like text or attributes. Note that the string discarding options will be ignored in this case.

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.

Note that the output_parent parameter may be None if there is no parent element in the current context (e.g. no content was added to the output tree yet).

Call this method to process the XSLT content of the extension element itself.
