init(self, sld_file=None)
(Constructor)

source code

Create a new SLD document. If an sld file is provided, this constructor will fetch the SLD schema from the internet and validate the file against that schema.

Parameters:

sld_file (string) - The name of a pre-existing SLD file.

Overrides: object.__init__

deepcopy(self, memo)

source code

Perform a deep copy. Instead of copying references to the schema object, create a new SLD, and deepcopy the SLD node.

normalize(self)

source code

Normalize this node and all child nodes prior to validation. The SLD is modified in place.

validate(self)

source code

Validate the current file against the SLD schema. This first normalizes the SLD document, then validates it. Any schema validation error messages are logged at the INFO level.
