Error: The node to be inserted is from a different document context

[schnell]

I'm getting an error that I'm very confused about. I'm trying to
generate an XML file completely from scratch in code. Here is the code
fragment that is causing me headaches:

Dim mBOEDOC as xml.xmldocument

dim inode as xml.xmlnode
dim iNode2 as xml.Xmlnode

mboedoc=new xml.xmldocument

inode2=mboedoc. createnode(xml. XmlNodeType.Doc ument, "BOETask", "")

iNode = mBOEDoc.createn ode(xml.xmlnode type.Element, "Program"," ")
inode2.appendch ild(inode)

Inode.innertext =mprogramname

The error is showing up on the appendchild procedure. I'm generating
both nodes from the same document. Why am I getting this error?

Thanks,

Michael Schnell

Here you seem to try to create a second document.
iNode = mBOEDoc.createn ode(xml.xmlnode type.Element, "Program"," ")
inode2.appendch ild(inode)

Inode.innertext =mprogramname

You need to use ImportNode if you want to copy a node from one owner
document to another:
inode2.AppendCh ild(inode2.Impo rtNode(inode, true))

Is iNode2 considered a different document from mBOEDoc when inode2 is a
node created inside mBOEDOc, the original xmldocument? I guess this is
what is really confusing me.

I create mBOEDoc with no nodes at all.

I then create inode2 (BOETask)

I then want to create a subnode to inode2, but since XMLNode doesn't
have a createNode function, i use the CreateNode function on the
document (mBOEDoc) to create iNode (Program). But iNode2 doesn't want
to accept iNode when I try to append it.

This is what is happening. Is this supposed to be happening?

I would use
new XmlDocument()
to create a new XML DOM document in .NET and then the factory methods
CreateElement
CreateAttribute
CreateComment
etc. to create new nodes for that document.

As for dealing with two document, yes, in that case you need to use the
ImportNode method of one document passing in a node from the other document.

I'm not trying to be difficult, but I'm still confused.

you say:

CreateElement
CreateAttribute
CreateComment
etc. to create new nodes for that document.

Isn't that what I say I'm doing earlier, when I say I create a
XMLDocument, create a base node and then try to create subnodes. I'm
not dealing with 2 documents, I'm only dealing with one (mBOEDoc) but
with several nodes within it.

Thank you,

Why do you use
mboedoc.createn ode(xml.XmlNode Type.Document, "BOETask", "")
^^^^^^^^^^^^^^^ ^^^^^^^^^
then, that looks to me like creating a second document and that is why
you get the error later.
