[Geoserver-users] Xml query help

All,

I have a Geoserver request that works via the url, and looks like this:

http://web1.cei.psu.edu:8080/geoserver/wfs?request=GetFeature&typeName=cei:s
sa_48&PropertyName=areasymbol,areaname,the_geom&Filter=<Filter><Or><Property
IsEqualTo><PropertyName>areasymbol</PropertyName><Literal>CA011</Literal></P
ropertyIsEqualTo></Or></Filter>

This is to get a few attributes for one feature, which has areasymbol=CA011.
My problem is that I would like to do this for many (300?) features, but it
seems to break at about 50 features....I guess the url string is too long?

So I tried doing the same request via xml, which looks like this (again, for
one feature):

<GetFeature service="WFS" version="1.0.0" outputFormat="GML2">
  <Query typeName="cei:ssa_48">
    <PropertyName>areasymbol</PropertyName>
    <PropertyName>areaname</PropertyName>
    <PropertyName>the_geom</PropertyName>
    <Filter>
      <Or>
        <PropertyIsEqualTo>
          <PropertyName>areasymbol</PropertyName>
          <Literal>CA011</Literal>
        </PropertyIsEqualTo>
      </Or>
     </Filter>
   </Query>
</GetFeature>

But with this I get the error:

<ServiceExceptionReport version="1.2.0"
xsi:schemaLocation="http://www.opengis.net/ogc
http://web1.cei.psu.edu:8080/geoserver/schemas//wfs/1.0.0/OGC-exception.xsd&quot;

<ServiceException>
    No request recognized. The REQUEST parameter must be one of GetFeature,
GetFeatureWithLock, DescribeFeatureType, LockFeature, or Transaction.
</ServiceException>
</ServiceExceptionReport>

Is the format correct for my xml? How does it know that request= this xml?
Do I need all the namespaces and schemas and such in the xml (which I always
see in the examples from the spec, but usually don't seem necessary in most
of my queries/filters)? And is there a more elegant way to do this request?
I have the client doing some agraggating of the attributes of some features,
and then going back to get the_geom (which is the point of this query).

Thanks,
Steve

Hi Stephen,

  Perhaps you could try adding the namespaces like this and see if you
get results:

I be able just to tack this xml onto the end of ..../geoserver/wfs? And

Steve,

How, exactly, are you sending this "all-xml" request?

If you're trying to send it by creating a url like this:

http://my-server:8080/geoserver/wfs?&lt;XML REQUEST HERE...>

then that won't work.

urls in the browser address-bar are fetched via "GET", while an all-xml request must be sent via POST.

If you have a unix box (or cygwin) around, you can try the following command-line-based method.

1) Save your XML query to a file (perhaps called "query.xml")
2) use the following command-line with a recent version of 'wget', all on one line:

$ wget -O result_file_name.xml --post-file=query.xml http://server:8080/geoserver/wfs

This will open a TCP connection to port 8080 on your geoserver server machine, and then use HTTP-POST to deposit the body of the XML request into the HTTP request, and should get you what you're looking for.

Let me know if that works for you!

--saul

Hi Steve,

  Another way to test this is to use the GeoServer "Demo Request".
Paste in your url into the 'url:' text box for example:
http://localhost:80/geoserver/wfs
Then paste a copy of the xml into the 'body:' text box. Then hit submit to
send a Post and examine the resulting GML.

Randy et al,

Thanks for all your help. I'm using Flashas my client, and the sendXML
method is supposed to use POST, but in the fine print they say that in test
mode it only uses GET! So that was one of the problems; I later found
through the error logs that the xerces jar was not present, so even when the
xml request was good it wasn't being parsed....so I loaded that and
everything is working great.

Thanks,
Steve

   </wfs:Query>
</wfs:GetFeature>

Yet I still get this error:

<ServiceExceptionReport version="1.2.0"
xsi:schemaLocation="http://www.opengis.net/ogc
http://web1.cei.psu.edu:8080/geoserver/schemas//wfs/1.0.0/OGC-exception.xsd&quot;

<ServiceException>
    No request recognized. The REQUEST parameter must be one of GetFeature,
GetFeatureWithLock, DescribeFeatureType, LockFeature, or Transaction.
</ServiceException>
</ServiceExceptionReport>

Any thoughts? Am I correct that the url for the service is the same as it
is for sending values thru the url string: ...../geoserver/wfs? ? Should
I be able just to tack this xml onto the end of ..../geoserver/wfs? And
have it work. It seems like there should be something in there saying
"request=" and then the xml.

Thanks again,
Steve

Hi Stephen,

  Perhaps you could try adding the namespaces like this and see if you
get results:
<?xml version='1.0' encoding='UTF-16' standalone='yes'?> <wfs:GetFeature
service="WFS" version="1.0.0"
  outputFormat="GML2"
  xmlns:wfs="http://www.opengis.net/wfs&quot;
  xmlns:ogc="http://www.opengis.net/ogc&quot;
  xmlns:gml="http://www.opengis.net/gml&quot;
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance&quot;
  xsi:schemaLocation="http://www.opengis.net/wfs
                      http://schemas.opengis.net/wfs/1.0.0/WFS-basic.xsd&quot;&gt;

  <wfs:Query typeName="cei:ssa_48">
    <ogc:PropertyName>areasymbol</ogc:PropertyName>
    <ogc:PropertyName>areaname</ogc:PropertyName>
    <ogc:PropertyName>the_geom</ogc:PropertyName>
    <ogc:Filter>
      <ogc:Or>
        <ogc:PropertyIsEqualTo>
          <ogc:PropertyName>areasymbol</ogc:PropertyName>
          <ogc:Literal>CA011</ogc:Literal>
        </ogc:PropertyIsEqualTo>
      </ogc:Or>
     </ogc:Filter>
   </wfs:Query>
</wfs:GetFeature>

All,

I have a Geoserver request that works via the url, and looks like this:

http://web1.cei.psu.edu:8080/geoserver/wfs?request=GetFeature&typeName=cei:s
sa_48&PropertyName=areasymbol,areaname,the_geom&Filter=<Filter><Or><Property
IsEqualTo><PropertyName>areasymbol</PropertyName><Literal>CA011</Literal
IsEqualTo>></P
ropertyIsEqualTo></Or></Filter>

This is to get a few attributes for one feature, which has areasymbol=CA011.
My problem is that I would like to do this for many (300?) features, but it
seems to break at about 50 features....I guess the url string is too long?

So I tried doing the same request via xml, which looks like this (again, for
one feature):

<GetFeature service="WFS" version="1.0.0" outputFormat="GML2">
  <Query typeName="cei:ssa_48">
    <PropertyName>areasymbol</PropertyName>
    <PropertyName>areaname</PropertyName>
    <PropertyName>the_geom</PropertyName>
    <Filter>
      <Or>
        <PropertyIsEqualTo>
          <PropertyName>areasymbol</PropertyName>
          <Literal>CA011</Literal>
        </PropertyIsEqualTo>
      </Or>
     </Filter>
   </Query>
</GetFeature>

But with this I get the error:

<ServiceExceptionReport version="1.2.0"
xsi:schemaLocation="http://www.opengis.net/ogc
http://web1.cei.psu.edu:8080/geoserver/schemas//wfs/1.0.0/OGC-exception.xsd&quot;

<ServiceException>
    No request recognized. The REQUEST parameter must be one of GetFeature,
GetFeatureWithLock, DescribeFeatureType, LockFeature, or Transaction.
</ServiceException>
</ServiceExceptionReport>

Is the format correct for my xml? How does it know that request= this xml?
Do I need all the namespaces and schemas and such in the xml (which I always
see in the examples from the spec, but usually don't seem necessary in most
of my queries/filters)? And is there a more elegant way to do this request?
I have the client doing some agraggating of the attributes of some features,
and then going back to get the_geom (which is the point of this query).

Thanks,
Steve
