Description: python-sld
        ==========

        A python library for reading, writing, and manipulating SLD files.

        Requirements
        ============

        The lxml library is required for XML parsing and XML Schema validation. This
        requirement is listed in requirements.txt, and may be installed using pip with
        this command:

            > sudo pip install -r requirements.txt

        Installation
        ============

            > easy_install python-sld

            OR

            > pip install python-sld

        Usage
        =====

        Using python-sld to create SLD documents is as easy as instantiating a
        StyledLayerDescriptor class object.

            from sld import StyledLayerDescriptor
            mysld = StyledLayerDescriptor()

        You may also read an existing SLD document in by passing it as a parameter:

            from sld import StyledLayerDescriptor
            mysld = StyledLayerDescriptor('mysld.sld')

        Addition of most elements are performed on the parent element, since they are
        related to parent nodes in order to preserve compliance:

            nl = mysld.create_namedlayer()
            ustyle = nl.create_style()

        A couple class objects represent collections of nodes, such as Rules and
        CssParameters. They are properties of their parent classes (FeatureTypeStyle
        and Fill/Stroke/Font respectively). They behave as python lists, and you
        can access any of their items using a python list pattern:

            fts = ustyle.create_featuretypestyle()
            rule1 = fts.Rules[0]
            print len(fts.Rules)
            fts.Rules[0] = rule1

        Filter objects are pythonic, and when combined with the '+' operator, they
        become ogc:And filters.  When combined with the '|' operator, they become
        ogc:Or filters.

            from sld import Filter

            filter_1 = Filter(rule)
            # set filter 1 properties

            filter_2 = Filter(rule)
            # set filter 2 properties

            rule.Filter = filter_1 + filter_2

        You may also construct a filter from an expression when using the create_filter
        method on the Rule object:

            filter = rule.create_filter('population', '>', '100')


        Implementation
        ==============

        At the current time, python-sld does ''not'' support the full SLD
        specification. The current implementation supports the following SLD elements:

          - StyledLayerDescriptor
          - NamedLayer
          - Name (of NamedLayer)
          - UserStyle
          - Title (of UserStyle and Rule)
          - Abstract
          - FeatureTypeStyle
          - Rule
          - ogc:Filter
          - ogc:And
          - ogc:Or
          - ogc:PropertyIsNotEqualTo
          - ogc:PropertyIsLessThan
          - ogc:PropertyIsLessThanOrEqualTo
          - ogc:PropertyIsEqualTo
          - ogc:PropertyIsGreaterThanOrEqualTo
          - ogc:PropertyIsGreaterThan
          - ogc:PropertyIsLike
          - ogc:PropertyName
          - ogc:Literal
          - MinScaleDenominator
          - MaxScaleDenominator
          - PointSymbolizer
          - LineSymbolizer
          - PolygonSymbolizer
          - TextSymbolizer
          - Mark
          - Graphic
          - Fill
          - Stroke
          - Font
          - CssParameter
