Problems with XmlNode.InsertA fter

[The Kiddie]

Hi,
I am having major headaches with XmlNode.InsertA fter. This is the
format of my XML document

<?xml version="1.0" encoding="utf-8"?>
<Team name="Team">
<Players>
<Player>
<name> GK</name>
<age> 28 </age>
<position> GK</position>
</Player>
<Player>
<name> P1</name>
<age> 22 </age>
<position> GK</position>
</Player>
<Player>
<name> P2</name>
<age> 32 </age>
<position> D</position>
</Player>
<Player>
<name> P3</name>
<age> 27 </age>
<position> D</position>
</Player>
</Players>
<Staff>
<Manager>
<name> Manager </name>
</Manager>
<Assistant-Manager>
<name> Assistant Manager </name>
</Assistant-Manager>
<Physio>
<name> Physio </name>
</Physio>
</Staff>
</Team>

I can locate a node but when I try to do an insert after on that node
I get "The reference node is not a child of this node". This is the
code

XmlNode root2 = doc2.DocumentEl ement;

//Create a new Element.
XmlElement newPlayer = doc2.CreateElem ent ("Player");

//doc2.DocumentEl ement.FirstChil d.AppendChild (newPlayer); - this
works but I want to be able to control where exactly the new Player
goes
doc2.InsertAfte r (newPlayer, doc2.DocumentEl ement.FirstChil d);

// I have tried finding a Player Node and calling insertafter using
that node as a reference but that fails as well. I'd appreciate any
help.

Also If anyone knows where I can find the Syntax for XPathExpression s
please reply.

All the best,

JD

That should be
doc2.DocumentEl ement.InsertAft er(newPlayer,
doc2.DocumentEl ement.FirstChil d);

Thanks for that but it doesn't solve my problem. Ha, I just figured it
out. Here is the code that will work

doc2.DocumentEl ement.FirstChil d.InsertAfter(n ewPlayer,
doc2.DocumentEl ement.FirstChil d.ChildNodes[6]);

i'm still not exactly sure about the relationship between the node that
comes before the ".insertaft er" and the reference node (2nd parameter).

Also can anyone tell me the difference between an XMLNode and an
XMLElement

Cheers,

JD

It has to be the parent node.

XmlElement inherits from the more abstract XmlNode base type. A document is
composed of a bunch of nodes, nodes can be contained in other nodes, and this
simple structure is what creates the hierarchical (tree-like) form of an XML doc.

Here's the skinny on Node from the source,

http://www.w3.org/TR/2004/REC-DOM-Le...#ID-1950641247

you'll notice that as it's defined by the W3C, Node is an interface. This means
a node is never created directly. Instead, a specialized implementation of a Node
is what's created, and there's are several of these concrete nodes (comments,
processing instructions, CDATA sections, entity references, text, attributes,
etc.)

An element is a special kind of node, and it normally has a string representation
involving angle brackets, like this <name></name> or <name />. Elements can
contain attribute nodes, text nodes, other subordinate element nodes, comment
nodes, CDATA section nodes, entity references, processing instructions ...

The official definition is here,

http://www.w3.org/TR/2004/REC-DOM-Le...l#ID-745549614

In summary, everything is a node. Only tags are elements.
