        XSLTExtension

Base class of an XSLT extension element.
Instance Methods [hide private]
a new object with type S, a subtype of T
__new__(T, S, ...)
 
apply_templates(self, context, node, output_parent=None)
Call this method to retrieve the result of applying templates to an element.
 
execute(self, context, self_node, input_node, output_parent)
Execute this extension element.
 
process_children(self, context, output_parent=None)
Call this method to process the XSLT content of the extension element itself.

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, output_parent=None)

 

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 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.

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.

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).

process_children(self, context, output_parent=None)

 

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

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

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.
