I'm having some difficulty when using a Logical OR in a WFS query to get multiple postcodes. This code works fine when it's only 1 PropertyIsEqualTo filter, but when I wrap the OR around more than one PropertyIsEqualTo filter I get an exception.

POST http://intranet.nottscc.gov.uk/maps/wfs HTTP/1.1
User-Agent: Fiddler
Content-Type: text/xml
Host: intranet.nottscc.gov.uk
Content-Length: 1875
Expect: 100-continue

<wfs:GetFeature service="WFS" version="1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:wfs="http://www.opengis.net/wfs" xmlns:ogc="http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml" xmlns:ncc="http://nottinghamshire.gov.uk" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/wfs.xsd">
<wfs:Query typeName="ncc:OSCodepoint_15KM">

This is the Error message I get.

<?xml version="1.0" encoding="UTF-8"?>
<ows:ExceptionReport version="1.0.0" xsi:schemaLocation="http://www.opengis.net/ows http://intranet.nottscc.gov.uk/maps/schemas/ows/1.0.0/owsExceptionReport.xsd"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ows="http://www.opengis.net/ows">
  <ows:Exception exceptionCode="NoApplicableCode">
    <ows:ExceptionText>Error occurred getting features Invalid fid filter provides, has no fids inside Invalid fid filter provides, has no fids inside</ows:ExceptionText>

I'm using GeoServer to process the query.

Any help is much appreciated.

Use a capitalized Or instead of all-caps OR to wrap your criteria:

        <!-- Criteria -->

I can't find any definitive answers about case sensitivity in filters, but the XML schema on the OGC site uses "Or" instead of "OR".

Thanks very much, my hair is still intact. The mistake was using Mapserver for the examples mapserver.org/ogc/filter_encoding.html where they use CAPITALS and then implementing it with GeoServer where they don't. –  Tom Styles Jan 6 '12 at 8:25
XML is case sensitive and it should be Or –  iant Jan 6 '12 at 13:49
