Match Questions by Pattern

This function takes a single HTML file or tibble and finds all questions/answers that contain a specified pattern. It returns the question IDs (from the 'id' column) for rows where the answer contains the pattern.

Usage

match_questions(x, pattern, ignore.case = TRUE)

Arguments

x

Either a file path to an HTML file or a tibble with 'id' and 'answer'/'data' columns

pattern

A character string to search for in the answers

ignore.case

Logical; should the search be case-insensitive? (default: TRUE)

Value

A character vector of question IDs where the answer contains the pattern

Examples

# Search in a tibble
path <- system.file("extdata", "answers_html", package = "tutorial.helpers")

tibble <- gather_submissions(path, title = "stop")[[1]]

result <- match_questions(tibble, "http")

if (FALSE) { # \dontrun{
# Search in an HTML file
question_ids <- match_questions("path/to/submission.html", "temperance")
# Returns: c("temperance-16", "temperance-19")
} # }
