Hi There,
wfs post request should look like this:
<?xml version="1.0" ?>
<wfs:GetFeature service="WFS" version="1.1.0" outputFormat="text/xml;
subtype=gml/3.1.1" xmlns:wfs="http://www.opengis.net/wfs";
xmlns:ogc="http://www.opengis.net/ogc";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.opengis.net/wfs ../wfs/1.1.0/WFS.xsd">
<wfs:Query typeName="my_name">
<ogc:Filter>
...
</ogc:Filter>
</wfs:Query>
<wfs:Query typeName="my_layer2">
<ogc:Filter>
....
</ogc:Filter>
</wfs:Query>
</wfs:GetFeature>
You can check the xsds for more details at http://schemas.opengis.net/wfs/

Hi,
Thank you for your response, I'm able to request data from both layers
(typenames) this way, however I'd like to achieve this in OpenLayers.
So I've created a small demo application which uses XMLHttp to request
data from Mapserver.
http://webgis.fmt.bme.hu/gfi/xml.html
The requests are hard coded, please take a look at the source.
How could I achieve the below described functionality with XML request(s)?
Thanks in advance,
BR,
Attila

The following URL on your server gives the output for the 2 typenames
I believe:

Thank you guys, I've tried with comma and brackets as well, no
success so far :(

Hi,
you need to repeat your filter (comma-separated) IIRC.
I believe it should be brackets instead of comma: something like
...&FILTER=(<Filter>...</Filter>)(<Filter>...</Filter>)

Dear All,
I've two layers (elteresek and elteresek2), and I'd like to get
features
from both of them using WFS GetFeature request.
If I apply one typename at a time, it works correct, but if I
include
two typenames in the request only the first is processed and
included in
the response.
This works correct (note TYPENAME=elteresek):
http://webgis.fmt.bme.hu/cgi-bin/mvmNew?SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&TYPENAME=elteresek&Filter=<ogc:Filter
xmlns:ogc="http://www.opengis.net/ogc";><ogc:BBOX><ogc:PropertyName>msGeometry</ogc:PropertyName><gml:Envelope
xmlns:gml="http://www.opengis.net/gml";
srsName="EPSG:23700"><gml:lowerCorner>649971.6696
236508.4728</gml:lowerCorner><gml:upperCorner>651559.1688
237919.5832</gml:upperCorner></gml:Envelope></ogc:BBOX></ogc:Filter>
This works correct (note TYPENAME=elteresek2) as well:
http://webgis.fmt.bme.hu/cgi-bin/mvmNew?SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&TYPENAME=elteresek2&Filter=<ogc:Filter
xmlns:ogc="http://www.opengis.net/ogc";><ogc:BBOX><ogc:PropertyName>msGeometry</ogc:PropertyName><gml:Envelope
xmlns:gml="http://www.opengis.net/gml";
srsName="EPSG:23700"><gml:lowerCorner>649971.6696
236508.4728</gml:lowerCorner><gml:upperCorner>651559.1688
237919.5832</gml:upperCorner></gml:Envelope></ogc:BBOX></ogc:Filter>
But the reply for this link includes only the first typename (in
this
case elteresek):
http://webgis.fmt.bme.hu/cgi-bin/mvmNew?SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&TYPENAME=elteresek,elteresek2&Filter=<ogc:Filter
xmlns:ogc="http://www.opengis.net/ogc";><ogc:BBOX><ogc:PropertyName>msGeometry</ogc:PropertyName><gml:Envelope
xmlns:gml="http://www.opengis.net/gml";
srsName="EPSG:23700"><gml:lowerCorner>649971.6696
236508.4728</gml:lowerCorner><gml:upperCorner>651559.1688
237919.5832</gml:upperCorner></gml:Envelope></ogc:BBOX></ogc:Filter>
What am I doing wrong?
Thanks,
Attila
