| xmlApply {XML} | R Documentation |
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.
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, ...)
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. |
The result is that obtained from calling
the apply or sapply
on xmlChildren(x).
