[OpenLayers-Users] SLD_BODY with 'like' filter

[Andreas Hocevar]

Hi,

you could do something like the following:

var filter = new OpenLayers.Filter.Comparison({
    type: OpenLayers.Filter.Comparison.LIKE,
    property: "my_field",
    value: "*my?ext*" // * string wildcard, ? char wildcard
});

var rule = new OpenLayers.Rule({
    filter: filter
});

rule.symbolizer["Point" /* or "Line" or "Polygon" */] = {
    strokeColor: "#FF0000",
    fillColor: "#00FF00",
    /* other symbolizer properties here */
};

var style = new OpenLayers.Style("", {rules: [rule]});

var sld_body = new OpenLayers.Format.SLD().write({
    namedLayers: [{
        name: "your_layer_name",
        userStyles: [style]
    }]
});

Regards,
Andreas.
