Extract a <node> as a new XMLDocument?

[Carlos Albert]

Hello,

Would you tell me if there is a way to extract a single node as a new
xmldocument?

Thanks.

Carlos,
You would need to :
1) Create a new XmlDocument.
2) use the ImportNode method to bring in the node from the other XmlDocument.

See MSDN Library Help or online for code samples.

Tnx, but I tried to do this and I'm doing something very wrong (cause it
doesn't work at all):

Dim big_xml As New XmlDocument

big_xml.LoadXml(xml)

Dim small_xml As New XmlDocument

Dim result As XmlNode =
small_xml.ImportNode(big_xml.GetElementsByTagName("node_tag_name").Item(0),
True)

small_xml.DocumentElement.AppendChild(result)

Break up your code into smaller pieces so it's easier to see what is happening
on each line with debugger step-through.
Also, ensure the new document has the correct processing instruction, root
element, etc. to be valid.
Also, it looks to me like you are trying to import your node from the new
document instead of the original!

Made it work, thanks! =)

Dim big_xml As New XmlDocument
big_xml.LoadXml(xml)
Dim small_xml As New XmlDocument
Dim result As XmlNode
result =
small_xml.ImportNode(big_xml.GetElementsByTagName("small_xml").Item(0),
True)
small_xml.LoadXml("<small_xml>" & result.InnerXml & "</small_xml>")
