Search the text of a paper or list of paper objects. Also works on the table results of a search_text() call.
Usage
search_text(
paper,
pattern = ".*",
section = NULL,
return = c("sentence", "paragraph", "div", "section", "match", "id"),
ignore.case = TRUE,
fixed = FALSE,
perl = FALSE
)Arguments
- paper
a paper object or a list of paper objects
- pattern
the regex pattern to search for
- section
the section(s) to search in
- return
the kind of text to return, the full sentence, paragraph, div, or section that the text is in, or just the (regex) match, or all body text for a paper (id)
- ignore.case
whether to ignore case when text searching
- fixed
logical. If TRUE, pattern is a string to be matched as is. Overrides all conflicting arguments.
- perl
logical. Should Perl-compatible regexps be used?
Examples
filename <- demoxml()
paper <- read(filename)
search_text(paper, "p\\s*(=|<)\\s*[0-9\\.]+", return = "match")
#> # A tibble: 2 × 7
#> text section header div p s id
#> <chr> <chr> <chr> <dbl> <dbl> <int> <chr>
#> 1 p = 0.005. results Results 3 1 2 to_err_is_human
#> 2 p = 0.152. results Results 3 2 1 to_err_is_human
