xmlChildren

Gets the sub-nodes within an XMLNode object.

Description

These functions provide access to the children of the given XML node. The simple accessor returns a list of child XMLNode objects within an XMLNode object.

The assignment operator (xmlChildren<-) sets the children of the node to the given value and returns the updated/modified node. No checking is currently done on the type and values of the right hand side. This allows the children of the node to be arbitrary R objects. This can be useful but means that one cannot rely on any structure in a node being present..

Usage

xmlChildren(x, addNames= TRUE, ...)

Arguments

`x`	an object of class XMLNode.
`addNames`	a logical value indicating whether to add the XML names of the nodes as names of the R list. This is only relevant for XMLInternalNode objects as XMLNode objects in R already have R-level names.
`...`	additional arguments for the particular methods, e.g. `omitTypes` for an XMLInternalNode.

Value

A list whose elements are sub-nodes of the user-specified XMLNode. These are also of class XMLNode.
