Case Insensitive PropertyName Evaluation in SLD

Question

I have a table layer_styles created by QGIS and, inside this table, the column stylesld.

The problem is that the PropertyNames (column names) stored inside this column and the generated SLD that geoserver explorer creates (and sends to geoserver) are UPPERCASE too, but in postgis, the column names of tables are LOWERCASE.

Is there a way to transform the LOWERCASE/UPPERCASE in column name(PropertyName) inside SLD or use a case insensitive evaluation on column name (PropertyName) ?

For example:

<ogc:Filter xmlns:ogc=""http://www.opengis.net/ogc"">
  <ogc:PropertyIsEqualTo>
    <ogc:PropertyName>
      <CaseInsensitive>TENSAO_OPE</CaseInsensitive>
    </ogc:PropertyName>
    <ogc:Literal>138 KV</ogc:Literal>
  </ogc:PropertyIsEqualTo>
</ogc:Filter>

Note that CaseInsensitive tag is only an example to explain what I need.

Answer 1

Checking the SLD cookbook you could try the function strToUpperCase:

<ogc:Function name="strToUpperCase">
    <ogc:PropertyName>TENSAO_OPE</ogc:PropertyName>
</ogc:Function>
