\name{xmlElementSummary}
\alias{xmlElementSummary}
\title{Frequency table of names of elements and attributes in XML content}
\description{
This function is used to get an understanding of the use
of element and attribute names in an XML document.
It uses a collection of handler functions to gather
the information via a SAX-style parser.
The distribution of attribute names is done within each
"type" of element (i.e. element name)
}
\usage{
xmlElementSummary(url, handlers = xmlElementSummaryHandlers(url))
}
%- maybe also 'usage' for other objects documented here.
\arguments{
\item{url}{the source of the XML content, e.g. a file, a URL, a
compressed file, or a character string}
\item{handlers}{the list of handler functions used to collect the
information. These are passed to the function
\code{\link{xmlEventParse}}
as the value for the \code{handlers} parameter.
}
}
\value{
A list with two elements
\item{nodeCounts}{a named vector of counts where the names are the
(XML namespace qualified) element names in the XML content}
\item{attributes}{a list with as many elements as there are elements
in the \code{nodeCounts} element of the result. Each element of this
sub-list gives the frequency counts for the different attributes seen within
the XML elements with that name.}
