Question

I’m simply trying to merge 2 xml documents (adding nodes from one into the other). I’ve done some Google searching, and tried a few things, but I always get the same error ‘The node to be inserted is from a different document context’

I’m sure I’m missing something simple, just seems like this should not be that difficult.

Here’s my code:

    Dim xmlDoc482 As XmlDocument = New XmlDocument     Dim xmlDoc486 As XmlDocument = New XmlDocument     Dim xmlDoc490 As XmlDocument = New XmlDocument      xmlDoc482.LoadXml(strSettlement482)     xmlDoc486.LoadXml(strSettlement486)     xmlDoc490.LoadXml(strSettlement490)      Dim xmlSummarysNode490 As XmlNode = xmlDoc486('Summarys')     Dim xmlSummaryNode482 As XmlNode = xmlDoc482('Summarys').LastChild     Dim xmlSummaryNode486 As XmlNode = xmlDoc486('Summarys').LastChild      Dim nodeDest As XmlNode     nodeDest = xmlDoc490.ImportNode(xmlSummaryNode482, True)     xmlSummarysNode490.AppendChild(nodeDest)      nodeDest = xmlDoc490.ImportNode(xmlSummaryNode486, True)     xmlSummarysNode490.AppendChild(nodeDest)

This works great, other then my stupid, stupid typo

This:

Dim xmlSummarysNode490 As XmlNode = xmlDoc486('Summarys') 

Should be This:

Dim xmlSummarysNode490 As XmlNode = xmlDoc490('Summarys') 

An element/node must be added using the document you’re adding it to.
