\title{Extract or modify the text}
\usage{
xml_text(x, trim = FALSE)
xml_text(x) <- value
xml_set_text(x, value)
xml_double(x)
xml_integer(x)
}
\arguments{
\item{x}{A document, node, or node set.}
\item{trim}{If \code{TRUE} will trim leading and trailing spaces.}
\item{value}{character vector with replacement text.}
}
\value{
A character vector, the same length as x.
}
\description{
\code{xml_text} returns a character vector, \code{xml_double} returns a
numeric vector, \code{xml_integer} returns an integer vector.
}
\examples{
x <- read_xml("<p>This is some text. This is <b>bold!</b></p>")
xml_text(x)
xml_text(xml_children(x))
x <- read_xml("<x>This is some text. <x>This is some nested text.</x></x>")
xml_text(x)
xml_text(xml_find_all(x, "//x"))
x <- read_xml("<p> Some text </p>")
xml_text(x, trim = TRUE)
# xml_double() and xml_integer() are useful for extracting numeric attributes
x <- read_xml("<plot><point x='1' y='2' /><point x='2' y='1' /></plot>")
xml_integer(xml_find_all(x, "//@x"))
