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,
exclude = FALSE,
search_header = FALSE
)Arguments
- paper
a paper object or a list of paper objects
- pattern
the regex pattern to search for, if a vector with length > 1, the patterns will be searched separately and combined
- 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?
- exclude
should matches be included or excluded
- search_header
also search the header
Examples
filename <- demoxml()
paper <- read(filename)
search_text(paper, "p\\s*(=|<)\\s*[0-9\\.]+", return = "match")
