<div class="moz-cite-prefix">Thanks for your replies. Unfortunately
white space does not make a difference. <br>
<br>
I also tried following the same tests as outlined at:
<a class="moz-txt-link-freetext" href="http://mapserver.org/ogc/filter_encoding.html#tests">http://mapserver.org/ogc/filter_encoding.html#tests</a><br>
<br>
I used the following URL:<br>
<br>
<a class="moz-txt-link-freetext" href="http://demo.mapserver.org/cgi-bin/wfs?&VERSION=1.0.0&SERVICE=WFS&REQUEST=GetFeature&TYPENAME=cities&Filter=">http://demo.mapserver.org/cgi-bin/wfs?&VERSION=1.0.0&SERVICE=WFS&REQUEST=GetFeature&TYPENAME=cities&Filter=</a><Filter><PropertyIsNull><PropertyName>NAME</PropertyName></PropertyIsNull></Filter><br>
<br>
With the filter encoded this is as follows (this can be tested
directly):<br>
<br>
<a
href="http://demo.mapserver.org/cgi-bin/wfs?&VERSION=1.0.0&SERVICE=WFS&REQUEST=GetFeature&TYPENAME=cities&Filter=%3CFilter%3E%3CPropertyIsNull%3E%3CPropertyName%3ENAME%3C%2FPropertyName%3E%3C%2FPropertyIsNull%3E%3C%2FFilter%3E">http://demo.mapserver.org/cgi-bin/wfs?&VERSION=1.0.0&SERVICE=WFS&REQUEST=GetFeature&TYPENAME=cities&Filter=%3CFilter%3E%3CPropertyIsNull%3E%3CPropertyName%3ENAME%3C%2FPropertyName%3E%3C%2FPropertyIsNull%3E%3C%2FFilter%3E</a><br>
<br>
However I still get the following error:<br>
<br>
<span style="color: rgb(0, 0, 0); font-family: monospace;
font-size: 13px; font-style: normal; font-variant: normal;

error. Invalid or Unsupported FILTER in GetFeature :
<Filter><PropertyIsNull><PropertyName>NAME</PropertyName></PropertyIsNull><br>
<br>
</span><br>
I get the same when using VERSION=1.1.0.<br>

OpenLayers has a OpenLayers.Filter.Comparison.IS_NULL filter that produces
