title: JXLS - How to filter result of jx:each command by string occurence
body: <p>I'm trying to generate a spreadsheet document using a template with jxls commands. I want to filter the elements of a collection that does not contain a specific text.</p>
  
  <p>I attempted to do that using following jxls command:</p>
  
  <pre><code>jx:each(items="Quote.CostList" var="Cost" lastCell="B18" select="${Cost.Type != 'EXCLUDED_TYPE_1' and Cost.Type != 'EXCLUDED_TYPE_2'}")
  </code></pre>
  
  <p>When I execute the application to generate the spreadsheet I get the following error.</p>
  
  <pre><code>org.apache.commons.jexl2.JexlException$Parsing: org.jxls.expression.JexlExpressionEvaluator.&lt;init&gt;@1:82 parsing error near '... PE_2' ...'
  </code></pre>
