xmlApply {XML}R Documentation

Applies a function to each of the children of an XMLNode

Description

These methods are simple wrappers for the lapply and sapply functions. They operate on the sub-nodes of the XML node, and not on the fields of the node object itself.

Usage

xmlApply(X, FUN, ...)
xmlApply.XMLNode(X, FUN, ...)
xmlApply.XMLDocument(X, FUN, ...)
xmlApply.XMLDocumentContent(X, FUN, ...)
xmlSApply(X, FUN, ...)
xmlSApply.XMLNode(X, FUN, ...)
xmlSApply.XMLDocument(X, FUN, ...)

Arguments

X the XMLNode on whose children the regular apply or sapply is to be performed
FUN the function to apply to each child node. This is passed directly to the relevant apply function.
... additional arguments to be given to each invocation of FUN. This is passed directly to the relevant apply function.

Value

The result is that obtained from calling the apply or sapply on xmlChildren(x).
