This is different from xmlValue applied to the node.
That concatenates all of the text in the child nodes (and their descendants)
This is a faster version of xmlSApply(node, xmlValue)
the parent node whose child nodes we want to process
encoding
the encoding to use for the text. This should come
from the document itself. However, it can be useful to specify it if
the encoding has not been set for the document (e.g. if we are
constructing it node-by-node).
asVector
a logical value that controls whether the result is
returned as a character vector or as a list (FALSE).
len
an integer giving the number of elements we expect
returned. This is best left unspecified but can be provided if the
caller already knows the number of child nodes. This avoids
recomputing this and so provides a marginal speedup.
addNames
a logical value that controls whether we add the
element names to each element of the resulting vector. This makes it
easier to identify from which element each string came.
doc = xmlParse("a string some text another")
getChildrenStrings(xmlRoot(doc))
doc = xmlParse("a string some text anotherabcxyz")
getChildrenStrings(xmlRoot(doc))
