<br>
Do you need to add a reference to the assembly before importing from it?<br>
<br>
In the Silverlight chapter of IronPython in Action I use 'XmlReader' for parsing XML. I have already (in an earlier chapter) provided a wrapper over this that gives it a SAX like interface. The code worked unmodified on Silverlight!<br>

Hello,<br>
<br>
It seems that XmlDocument isn't available in Silverlight. The Linq dll ("System.Xml.Linq.dll") is listed between the client libraries, but when I add them to my Silverlight manifest file<br>
and try:<br>
<br>
from System.Xml.Linq import XDocument<br>
<br>
The following error occurs: "ManagedRuntimeError, SetProperty failed"<br>
<br>
What's the recommended way to query XML documents? A good XML library is essential at the client for doing AJAX (in our case: APAX), I wonder in the first place why XmlDocument isn't in Silverlight by default.<br>
I don't want to use a SAX parser like XmlReader.<br>
<br>
Jonathan<br>
<br>
<br>
PS: When the XML parsing works, I can present a working APAX example for querying a mysql database. It returns row after row every time the client does a request for the next row. The javascript version works, and I'm porting it now to Silverlight/IronPython.<br>
