Text pieces of nodes

The text nodes of each node's subtree, in tree order, as separate strings: the pieces html_text() concatenates. Boundaries between elements are kept, which matters when the markup, not whitespace, separates values (<td>1</td><td>2</td> is "1", "2", not "12"). Text inside <script>, <style> and <template> is skipped, as are comments.

Usage

html_strings(x, trim = FALSE, drop_empty = FALSE)

Arguments

x

A zuhtml_document or zuhtml_nodeset.

trim

If TRUE, remove leading and trailing whitespace from each piece.

drop_empty

If TRUE, drop pieces that are empty (after trimming, when trim = TRUE).

Value

A list as long as x of character vectors; NA_character_ for a missing node. A text node is its own single piece.

Examples

doc <- html_parse("<p>One <b>two</b>\n  <i> three </i></p>")

html_strings(p)
#> [[1]]
#> [1] "One "    "two"     "\n  "    " three "
#> 
html_strings(p, trim = TRUE, drop_empty = TRUE)
#> [[1]]
#> [1] "One"   "two"   "three"
