xml2 (version 1.3.6)

as_list: Coerce xml nodes to a list.

Description

This turns an XML document (or node or nodeset) into the equivalent R list. Note that this is as_list(), not as.list(): lapply() automatically calls as.list() on its inputs, so we can't override the default.

Usage

as_list(x, ns = character(), ...)

Arguments

x

A document, node, or node set.

ns

Optionally, a named vector giving prefix-url pairs, as produced by xml_ns(). If provided, all names will be explicitly qualified with the ns prefix, i.e. if the element bar is defined in namespace foo, it will be called foo:bar. (And similarly for attributes). Default namespaces must be given an explicit name. The ns is ignored when using xml_name<-() and xml_set_name().

...

Needed for compatibility with generic. Unused.

Details

as_list currently only handles the four most common types of children that an element might have:

• Other elements, converted to lists.

• Attributes, stored as R attributes. Attributes that have special meanings in R (class(), comment(), dim(), dimnames(), names(), row.names() and tsp()) are escaped with '.'

• Text, stored as a character vector.

Examples

as_list(read_xml(" a "))
as_list(read_xml("  "))
as_list(read_xml(""))
as_list(read_xml(""))
