Labview 7.1 integrating XML

Question

Hello,
We are currently trying to call standard XML documets / processes with Labview 7.1.  We are trying to call the XML document directly without additoinal middleware, but continue to receive the error messages below?
Could you provide some advsie or documentation on how we should proceeed with this integation?
** Note: If we upgraded to Labview version 8.2** we are able to directly connect to external XML sources with ease.  But since we have extensive amount of processes already in Labview Version 7.1 --> We would like to integrate them to realize the integration process enhansemnts sooner before we deploy Labview 8.2 world wide.
We keep getting the below error when trying to use the wsdl.  From what I understand so far, Labview has a .Net Web Services import wizard that automatically creates a dll based on the wsdl xml that I can then use in my code.  But the wizard gives the below error?
Create C# Code .vi

Where did you see that?
Are the VIs refered to there yours or NI's?
I know that 8.2 can work with web services, but not 7.1. In 7.x, you have two requirements for using a .NET DLL - you need to place it in the same directory as the top level VI and you need to register it in Tools>>Advanced>>.NET Assembly References. The registering does nothing other than tell LV where it should take DLLs it knows about from. It can work even if you don't register.
P.S. 7.1 has a problem with .NET where you drop a constructor and it hangs. There should be a patch for that.
P.P.S. What do you mean by

To me, this implies that you're trying to manipulate the string yourself or using LV's XML primitives (which won't work), but this is clearly not the case, since you're using .NET.
If you're trying to use MSXML, you can find some implementations around, like LabXML or by searching the LAVA forums.
