tidyHTML: Tidy HTML content

In omegahat/RTidyHTML: Tidy HTML documents

Tidy HTML content

Description

This function processes an HTML document and tidys the malformed nodes so that they are legitimate TML, i.e. with end nodes (</li>, </p>) and attributes enclosed in quotes. This also corrects the HTML in various ways.

The resulting document can then be used with a more correct structure. This, for example, makes processing it with the XML parsing facilities more straightforward.

This uses libtidy from http://tidy.sourceforge.net

Usage

tidyHTML(doc, asXHTML = FALSE, 
         asText = inherits(doc, "AsIs") ||
                    (!file.exists(doc) && length(grep("\\<", doc))),
         size = nchar(doc)*1.2, withErrors = FALSE)

Arguments

doc	the name of the file containing the HTML document or the contents of the HTML itself.
asXHTML	a logical value controlling whether the result is output as XHTML.
asText	a logical value indicating whether the value of doc is the HTML content or the name of a file.
size	an integer scalar giving a guess of the size of the resulting tidied document
withErrors	a logical value controlling whether a string giving the errors in the input document are also returned

Value

If withErrors is TRUE, a list with two elements named doc and errors, both of which are scalar strings.

If withErrors is FALSE, a character string containing the tidied document's contents.
