[mapguide-users] GetSelectionXML() how to read <Class id='Default:xxx'> in PHP.

[Alain Lebatard]

Hi Maciej,

Have you looked at the MgSelection class? It can parse the XML text
representing the selection and give you the list of layers that are part
of this selection.

The following code output the name of the selected layers

  $sel = new MgSelection($map, $xmlSelText);
  $layers = $sel->GetLayers();
  for($i = 0; $i < $layers->GetCount(); $i++)
  {
     $layer = $layers->GetItem($i);
     echo $layer->GetName() . "\n";
  }

hi good people!



i work on 2 layer, all are selectable and visible on map, all object on 
any of this 2 layer have a data (name,id, etc).

when user click on object it is selected , so i can get xml of this 
selection...so i get it.

First selected  object on  layer "test" ganerate this XML

<?xml version="1.0" encoding="UTF-8"?>
<FeatureSet>
<Layer id="376274-234-234-234-23-4234">
<Class id="Default:test">
<ID>BQAAAA==</ID>
</Layer>
</FeatureSet>



First selected  object on  layer "test2" ganerate this XML

<?xml version="1.0" encoding="UTF-8"?>
<FeatureSet>
<Layer id="376274-234-234-234-23-4234">
<Class id="Default:test2">
<ID>BQAAAA==</ID>
</Layer>
</FeatureSet>


question is how can i get form this 2 xml , name of cliked layer
<Class id="Default:test"> --> layer: test

..i second
<Class id="Default:test2"> --> layer: test2

if  have name of layer i can read (id,name , etc.)of selected 
object.that is what i want.

is there any MG API solution? or i must use ex. SimpleXML to work whit 
this xml.

...the best way mayby in future

$layer_name=$object->GetLayerName($xml_of_selected_object);
