how to find all the child nodes inside the matched elements (including text nodes)?
in jquery its quite simple
for instance
$("br").parent().contents().each(function() {
but for nokogiri, xpath,
its not w开发者_如何学Corking out quite well
var = doc.xpath('//br/following-sibling::text()|//br/preceding-sibling::text()').map do |fruit| fruit.to_s.strip end
require 'rubygems'
require 'nokogiri'
doc = Nokogiri::HTML(DATA.read)
fruits = doc.xpath('//br/../text()').map { |text| text.content.strip }
p fruits
__END__
<html>
<body>
<div>
apple<br>
banana<br>
cherry<br>
orange<br>
</div>
</body>
I'm not familiar with nokogiri, but are you trying to find all the children of any element that contains a <br/>? If so, then try:
//*[br]/node()
In any case, using text() will only match text nodes, and not any sibling elements, which may or may not be what you want. If you actually only want text nodes, then
//*[br]/text()
should do the trick.
