readHTMLList: Read data in an HTML list or all lists in a document

Description Usage Arguments Value Author(s) See Also Examples

Description

This function and its methods are somewhat similar to readHTMLTable but read the contents of lists in an HTML document. We can specify the URL of the document or an already parsed document or an individual node within the document.

Usage

1
readHTMLList(doc, trim = TRUE, elFun = xmlValue, which = integer(), ...)

Arguments

doc

the URL of the document or the parsed HTML document or an individual node.

trim

a logical value indicating whether we should remove leading and trailing white space in each list item when returning it

elFun

a function that is used to process each list item node (li). This provides an opportunity to customize how each node is processed, for example accessing attributes on the list item or on its contents such as links in the items.

which

an index or name which or vector of same which identifies which list nodes to process in the overall document. This is for subsetting particular lists rather than processing them all.

...

additional arguments passed to htmlParse and for the specific methods.

Value

A list of character vectors or lists, with one element for each list in the document. If only one list is being read (by specifying which as a single identifier), that is returned as is.
