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

readHTMLList {XML} | R Documentation

## Read data in an HTML list or all lists in a document

### 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

    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.
