<p class=MsoNormal>Hi, for regular expression you need to set the parameters
FILTERITEM and FILTER. <br>
>From the documentation (<a
href="http://mapserver.org/mapfile/expressions.html#regular-expression-comparison)">http://mapserver.org/mapfile/expressions.html#regular-expression-comparison</a>)<br>
<br>
LAYER<br>
NAME "regexp-example"<br>
FILTERITEM "placename"<br>
FILTER /hotel/ <o:p></o:p></p>
<pre><o:p> </o:p></pre><pre> ...<o:p></o:p></pre><pre>END<o:p></o:p></pre>
<p class=MsoNormal><br>
I think, the parameter EXPRESSION does not allow regular expression comparison.<br>
<br>
Cheers,<br>
