Yes. Thanks for the answer. This is an extract of the code.
puntigml = new OpenLayers.Layer.GML("Specimens",
"/gis/GeoLayer.gml",{projection: new OpenLayers.Projection("EPSG:4326")});
map.addLayer(puntigml);
select_feature_control =new OpenLayers.Control.SelectFeature(
puntigml,
{
multiple: false,
toggle: true,
multipleKey: 'shiftKey',
toggleKey: 'ctrlKey',
box: true
}
);
map.addControl(select_feature_control);
function selezione_elemento(event) {
//info record
var tipo=event.feature.attributes.type;// comment#1
var collect=event.feature.attributes.place.name; //comment#2
var famiglia=event.feature.attributes.family;
var specie=event.feature.attributes.species;
document.getElementById('tipo').innerHTML=tipo;
document.getElementById('collection').innerHTML=collect;
}
puntigml.events.register('featureselected', this, selezione_elemento);
This is an example of my gml file
<gml:featureMember>
<gml:Specimens>
<type>herbaria</type> // comment#1
<species>Quercus cerris L.</species>
<place>
<name>Valle di Copogna-Monte Lago</name> //comment #2
<town>Serravalle di Chienti</town>
<province>Macerata</province>
<region>Marche</region>
<country>Italia</country>
</place>
<ogr:geometryProperty>
<gml:Polygon srsName="EPSG:4326">
<gml:outerBoundaryIs>
<gml:LinearRing>
<gml:coordinates>12.916666749999999,43.100000000000001 13,43.100000000000001
13,43.149999999999999 12.916666749999999,43.149999999999999
12.916666749999999,43.100000000000001</gml:coordinates></gml:LinearRing>
</gml:outerBoundaryIs>
</gml:Polygon>
</ogr:geometryProperty>
</gml:Specimens>
</gml:featureMember>
When I try to access to a first order node like <type> or <species> the
selection function works (look comment #1) but when I try to access to a subtag
doesn't extract any information and the firebug result is
event.feature.place is undefined - var collect=event.feature.place.name;
Thanks again,
Francesco

Oggetto: Re: [OpenLayers-Users] gml and attributes
Hello,
"event.feature.field1.field2" is normally the right way to access to
attribute "field2".
1. Check if "field2" is correctly written.
2. It can be other thing
Can you give us the real lines (not with <field1><field2>...</field1>)?
It can help more.
