[mapguide-users] Modify mapdefinition in a layout

[euskalmap]

Hi,
In fact, before modification, i have 
MgResourceIdentifier webLayoutId = new MgResourceIdentifier(pst_weblayout) 
with pst_weblayout = "Library://Ag Base/MyLayout.WebLayout" 
I search the xml node for modify Mapdefinition resource and 
after modification i have in instruction 
webLayoutId = new MgResourceIdentifier(str_NewMapDefinition) 
with str_NewMapDefinition=Session:xxxxxxxxx//MyMap.MapDefinition
So, i set the resource and i have the message 'An exception occurred in the
XML parser.'
I say it is simply to migrate vb to c#, but before i want to understand.
I have use same sample who use this method on the forum; but i do not
explain where is my bug?
thanks a lot for your help
