Method Details

[hide private]

flatten(self)

source code

returns a string representation of the text content of the tree.

This default implementation will only work if you returned all parsed elements as children. This, in turn, is something you only want to do if you are sure that the node is question will not be morphed.

Otherwise, override it to create an SQL fragment out of the parsed attributes.
