[OpenLayers-Users] Read WFS Layer attributes

[vGIS]

*How *is it possible *to read attributes of a layer*?


For instance geoserver could deliver the layer structure with the URL:

http://localhost:8080/geoserver/wfs/DescribeFeatureType?version=1.1.0&typename=topp:poly


That returns the XML:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:cite="http://www.opengeospatial.net/cite"
xmlns:gml="http://www.opengis.net/gml"
xmlns:it.geosolutions="http://www.geo-solutions.it"
xmlns:nurc="http://www.nurc.nato.int" xmlns:sde="http://geoserver.sf.net"
xmlns:sf="http://www.openplans.org/spearfish"
xmlns:tiger="http://www.census.gov"
xmlns:topp="http://www.openplans.org/topp" elementFormDefault="qualified"
targetNamespace="http://www.openplans.org/topp">
  <xsd:import namespace="http://www.opengis.net/gml"
schemaLocation="http://localhost:8080/geoserver/schemas/gml/3.1.1/base/gml.xsd"/>
  <xsd:complexType name="polyType">
    <xsd:complexContent>
      <xsd:extension base="gml:AbstractFeatureType">
        <xsd:sequence>
          <xsd:element maxOccurs="1" minOccurs="0" name="objectid"
nillable="true" type="xsd:int"/>
          <xsd:element maxOccurs="1" minOccurs="0" name="shape_leng"
nillable="true" type="xsd:decimal"/>
          <xsd:element maxOccurs="1" minOccurs="0" name="shape_area"
nillable="true" type="xsd:decimal"/>
          <xsd:element maxOccurs="1" minOccurs="0" name="geom"
nillable="true" type="gml:SurfacePropertyType"/>
          <xsd:element maxOccurs="1" minOccurs="0" <b>name="typ"*
nillable="true" type="xsd:*int*"/>
          <xsd:element maxOccurs="1" minOccurs="0" <b>name="tst"*
nillable="true" type="xsd:*string*"/>
        </xsd:sequence>
      </xsd:extension>
    </xsd:complexContent>
  </xsd:complexType>
  <xsd:element name="poly" substitutionGroup="gml:_Feature"
type="topp:polyType"/>
</xsd:schema>

So the XML contains the additional defined attributes. And there might be a
way to read that XML, but there needs to be a not that difficult way.

*Has anyone an idea, how to read the existing attributes of a wfs layer?*

Kind regards,
vGIS
