XmlNodeReader
Class NodePathParser

NodePathParser is a helper class used by XmlNodeReader that converts a "nodeName.nodeName.nodeName" type string to an array of node names, and pulls out the attribute name and last node name for reference. The special rules for a "node path" are:

• node names and attribute names are separated by a period (".")
• attribute names must begin with "@" (like "@href" for the "href" attribute)
• attribute names must be the last part of the node path
• if a node name or attribute name contains a period, replace the period with two periods (so the node name "author.name" becomes "author..name" in the node path)

New

Public New(nodePath As String)

Creates a new NodePathParser from the given node path string.

getArray

Public Function getArray() As Variant

Returns a string array with one element for each node name in the node path. If the node path is empty (or only contains an attribute name) this will return an array with a single empty string element.

getAttName

Public Function getAttName() As String

Returns the attribute name in the node path, if any.

getNodeName

Public Function getNodeName() As String

Returns the last (right-most) node name in the node path, if any.

getPath

Public Function getPath() As String

Returns the node path string that was passed when this object was created, or when parseNodePath() was called, with all spaces stripped and any trailing attribute name removed.

parseNodePath

Public Function parseNodePath(np As String) As Variant

Returns a string array with one element for each node name in the node path, and also sets all the internal references in this object to reflect this node path. This method is called by the New() sub when the object is instantiated.

SplitNodePath

Private Function SplitNodePath(Byval npath As String) As Variant

Internal function used to convert a node path to an array, also changing ".." references in node names to "."
