[mapguide-users] Search accross multiple layers

[Jamo181]

So say I add features to the selection set then convert it into a feature
reader ? firstly is this possible...?

And another little feature I've been working on is being able to select all
features found when the search finishes and zoom the selection.....

I've been trying to accomplish this by doing the following to the
search.aspx
steps are as follows.
1.create another MgFeatureReader with all features.
2.Convert to selection.
3.convert to string.
4.add XML Selection to vals so it can be read by the initdocument()
function.
5.add new String xmlSel = %s; to end of declares
6.add ZoomSelection(); to InitDocument()
7.add functoin ZoomSelection()....

the xml seems to come accross correctly however...

i'm having trouble now getting it to convert back to a string ready to be
used in the SetSelectionXML
how do I get it to come across correctly?

<?xml version="1.0" encoding="UTF-8"?><FeatureSet
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="FeatureSet-1.0.0.xsd"> <Layer
id="f5e21168-ffff-ffff-8000-005056853938">  <Class id="Default:cadFREE">  
<ID>IwAAAA==</ID>   <ID>KQAAAA==</ID>   <ID>MQAAAA==</ID>  </Class>
</Layer></FeatureSet>


//search.aspx
            MgFeatureReader features1 = featureSrvc.SelectFeatures(srcId,
featureClassName, opts);

            MgSelection mySel = new MgSelection(map);
            mySel.AddFeatures(layer, features1, 0);
            String xmlSel = EscapeForHtml(mySel.ToXml());

//vals to be sent to search.templ

                String[] vals = {
                           
colCount.ToString(NumberFormatInfo.InvariantInfo),
                            target.ToString(NumberFormatInfo.InvariantInfo),
                            popup.ToString(NumberFormatInfo.InvariantInfo),
                            xmlSel
                                };

//search.templ

String xmlSel = %s;

function InitDocument()
{
    document.onmousedown = OnMouseDown;
    ZoomSelection();
}

function ZoomSelection()
{
    GetParent().SetSelectionXML(xmlSel);
}
