Mapserver 7 returns an error when WFS GetFeature filters contain parens

[asaunier]

Hi,

with Mapserver 7 (built on Sep, 2nd) I have noticed that WFS GetFeature requests return an error when using parens in a property value filter. Actually only the opening paren seems to be a problem, not the closing one.

For instance:

<wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs" service="WFS" version="1.1.0" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/wfs.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><wfs:Query typeName="feature:monuments" srsName="EPSG:3857" xmlns:feature="http://mapserver.gis.umn.edu/mapserver"><ogc:Filter xmlns:ogc="http://www.opengis.net/ogc"><ogc:PropertyIsEqualTo matchCase="false"><ogc:PropertyName>nom</ogc:PropertyName><ogc:Literal>foo</ogc:Literal></ogc:PropertyIsEqualTo></ogc:Filter></wfs:Query></wfs:GetFeature>

works as expected, whereas

<wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs" service="WFS" version="1.1.0" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/wfs.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><wfs:Query typeName="feature:monuments" srsName="EPSG:3857" xmlns:feature="http://mapserver.gis.umn.edu/mapserver"><ogc:Filter xmlns:ogc="http://www.opengis.net/ogc"><ogc:PropertyIsEqualTo matchCase="false"><ogc:PropertyName>nom</ogc:PropertyName><ogc:Literal>foo (bar)</ogc:Literal></ogc:PropertyIsEqualTo></ogc:Filter></wfs:Query></wfs:GetFeature>

returns

<ows:ExceptionReport xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.1.0" xmlns:ows="http://www.opengis.net/ows" language="en-US" xsi:schemaLocation="http://www.opengis.net/ows http://schemas.opengis.net/ows/1.0.0/owsExceptionReport.xsd">
  <ows:Exception locator="filter" exceptionCode="InvalidParameterValue">
    <ows:ExceptionText>msWFSGetFeature(): WFS server error. Wrong number of filter elements, one filter must be specified for each feature type listed in the TYPENAME parameter.</ows:ExceptionText>
  </ows:Exception>
</ows:ExceptionReport>

Both requests work fine with Mapserver 6.0.1.

I have the same problem with another dev version built a few months ago.

Issue seems unrelated to RFC 91 changes. --Steve

Fixed. The issue could been triggered with requests on multiple layers/filters on previous releases. WFS 2.0 work just made the bug more easily triggered
