identify_elements

table.Node

a vector that contains information for the identification of the header row(s). A numeric vector can be specified where each element corresponds to the table rows. A character vector may be specified that describes an XPath for the header rows. If left unspecified, htmltable tries to use semantic information from the HTML code

header

a vector that specifies which table rows should be used as body information. A numeric vector can be specified where each element corresponds to a table row. A character vector may be specified that describes an XPath for the body rows. If left unspecified, htmltable tries to use semantic information from the HTML code

body

logical, should htmltab ensure complementarity of header, inbody header and
body elements (default TRUE)?

Assemble XPath expressions for header and body

HTML tables are a valuable data source but extracting and recasting
these data into a useful format can be tedious. This package allows to collect
structured information from HTML tables. It is similar to `readHTMLTable()`
of the XML package but provides three major advantages. First, the function
automatically expands row and column spans in the header and body cells.
Second, users are given more control over the identification of header and body
rows which will end up in the R table, including semantic header information
that appear throughout the body. Third, the function preprocesses table code,
corrects common types of malformations, removes unneeded parts and so helps to
alleviate the need for tedious post-processing.
