xmlElementSummary {XML} | R Documentation

## 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))

### Arguments

`url` | the source of the XML content, e.g. a file, a URL, a compressed file, or a character string
`handlers` | the list of handler functions used to collect the information. These are passed to the function `xmlEventParse` as the value for the `handlers` parameter.

### Value

A list with two elements

`nodeCounts` | a named vector of counts where the names are the (XML namespace qualified) element names in the XML content
`attributes` | a list with as many elements as there are elements in the `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.
