Re: [Mapbuilder-devel] IE7/msxml5 issues

The problem I was seeing is definitely because the Sarissa DOMParser is
now schema validating XML documents.  This can be turned off in Sarissa
(as in the 3rd bullet below) however it's a change to Sarissa code.  We
should either suggest they include that change or just remember to add
that to our version of Sarissa.  Feedback on how to proceed here is
welcome.

Having said that however, I traced this to another problem in
ModelBase.js at line 191 or so:
if( (xmlHttp.responseXML !=3D null) && (xmlHttp.responseXML.root !=3D =
null)
&& (xmlHttp.responseXML.root.children.length>0) ) {

If this is changed back to just:=20
if (xmlHttp.responseXML !=3D null) {

The problem also goes away because the reponse doesn't get routed
through the DOMParser in this case. =20

Vincent: can you test that change to see if solves your issue?

I can't find any references to a responseXML.root property anywhere.
responseXML is supposed to be a DOM Document object and there is no root
property on that either.  So I'm sugesting that the extra tests in that
if statement are removed.  However, someone (Linda?) added those for a
reason so before I do that I'll hold off to hear objections.
