Re: [mvp-xml-help] XPathIteratorReader and ReadInnerXml method

[Oleg T. <ol...@tk...>]

Yeah, that sounds a bit weird. I believe you shouldn't call to 
iteratorReader.MoveToContent(); here. What it should perform in a 
nodeslit with virtual root node? I believe what it does - it moves to 
the first node. But why iteratorReader.Name is still gods - god knows 
why :) Might be a bug. Take sources and figure out what's going on there.
