I am just trying to spit out some information through the GML Parser example
so that I can use the bounding boxes in a search query. I have followed the
example located here -
http://dev.openlayers.org/releases/OpenLayers-2.10/examples/GMLParser.html
and I am using my own XML file which seems to be working ok. Unfortunately
my XML file has a bit different information when it comes to Geometry
coordinates, for each Feature of mine (I am trying to get Neighbourhood
features and basically it has neighourhood name, geometry etc) it spits out
what seems like the correct info from the lines html += "Feature:
Geometry: "+ features[feat].geometry+",";
Except I am having an issue. See each one of my geometries has the correct
bounding box above it which goes like -
<gml:boundedBy>
<gml:Box srsName="EPSG:4326">
<gml:coordinates>5786792.2831552,6983.36579454902
5799746.97353866,17582.612872094</gml:coordinates>
</gml:Box>
</gml:boundedBy>
<gml:featureMember>
<gmgml:Neighbourhoods fid="Neighbourhoods.18">
<gmgml:NEIGHBOURHOODID>18</gmgml:NEIGHBOURHOODID>
<gmgml:NEIGHBOURHOOD_NAME>Fairview</gmgml:NEIGHBOURHOOD_NAME>
<gmgml:LABEL_LINE1>Fairview</gmgml:LABEL_LINE1>
<gmgml:LABEL_LINE3> </gmgml:LABEL_LINE3>
<gmgml:YearBuilt>1973.82763980659</gmgml:YearBuilt>
<gmgml:Geometry>
<gml:Polygon srsName="EPSG:4326">
<gml:outerBoundaryIs>
<gml:LinearRing>
<gml:coordinates> There is a whole bunch of coordinates
here</gml:coordinates>
</gml:LinearRing>
</gml:outerBoundaryIs>
</gml:Polygon>
</gmgml:Geometry>
</gmgml:Neighbourhoods>
</gml:featureMember>
Sorry for the big mess there but basically what I am trying to do is get the
first <gml:boundedBy> value instead of the whole
<gml:LinearRing><gml:coordinates> (which is a whole bunch of coordinates
which I am guessing is just the area around my feature) because when I zoom
into these first bounded by coordinates it is indeed in the correct area for
the neighbourhood. Well I cannot get the GML parser to ignore my other
geometry and just spit out this bounding box stuff. I tried going like -
html += "Feature: Geometry: "+ features[feat].boundedBy+",";
But now instead of displaying the neighbourhood stuff with the huge list of
LinearRing coordinates it goes -
Feature: Geometry: undefined,
NEIGHBOURHOODID:18
NEIGHBOURHOOD_NAME:Fairview
LABEL_LINE1:Fairview
LABEL_LINE3:null
YearBuilt:1973.82763980659
etc. So I'm just wondering can I modify the code so that it spits out the
geometry inside the BoundedBy instead? Appreciate any advice hope this makes
somewhat sense as I am very confused about this topic.
