cell_line_lists: Template function for extracting lists of items related to...
In jimvine/rcellosaurus: Cellosaurus for R

Internal function, used by functions that gather things that are stored in the XML as lists. Each of these has a particular list container element, e.g. name-list, and an object element name.

1 2	cell_line_lists(cell_line, attrib = NULL, list_element, item_element, attrib_name, contents = TRUE)

`cell_line`	A node or nodeset referring to a cell-line or multiple cell-lines.
`attrib`	A character vector specifying which Types to output. If `NULL`, the function returns all values (i.e., unfiltered).
`list_element`	The XML element name for the list item
`item_element`	The XML element name for the objects within the list
`attrib_name`	The XML attribute name for the categorisation of list items
`contents`	Whether to report the contents of the list items rather than returning the whole of each XML node. See Details.

Some (but not all) of the objects support categorisation, e.g. names can be of type "identifier" or type "synonym". Where that is the case, this function takes both an argument with the category(ies) being filtered on (attrib) and the name of the categorisation (attrib_name), which is used to form the XPath search term.

The parameter contents defines whether to return the contents of the nodes found (using the XPath code /text()). In cases where the relevant information is stored as an attribute of the node rather than as text within it (e.g. references), we need to return the whole of the nodes, so specify contents = FALSE.
