require 'ronin/support/web'
include Ronin::Support::Web
html_parse "<html>...</html>"
# => #<Nokogiri::HTML::Document:...>
Parse an HTML string:
doc = html_parse("<html>\n <body>\n <p>Hello world</p>\n </body>\n</html>\n")
# =>
# #(Document:0x6ab8 {
# name = "document",
# children = [
# #(DTD:0x6be4 { name = "html" }),
# #(Element:0x6cd4 {
# name = "html",
# children = [
# #(Text "\n "),
# #(Element:0x6e64 {
# name = "body",
# children = [
# #(Text "\n "),

Parse a HTML file:
doc = html_open("index.html")
# => #<Nokogiri::HTML::Document:...>
Searching an HTML document using XPath or CSS-path:
nodes = doc.search('//div/p')
nodes = doc.search('div p.class')
# => [#<Nokogiri::HTML::Element:...>, ...]
node = doc.at('#id')
# => #<Nokogiri::HTML::Element:...>
Build a HTML document:
doc = html_build do
html {
head {
script(type: 'text/javascript', src: 'redirect.js')
}
}
end
puts doc.to_html
# <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
# <html><head><script src="redirect.js" type="text/javascript"></script></head></html>

xml_parse("<?xml version=\"1.0\"?>\n<users>\n <user>\n <name>admin</name>\n <password>0mni</password>\n <user>\n</users>\n")
# =>
# #(Document:0xdebc {
# name = "document",
# children = [
# #(Element:0xdfe8 {
# name = "users",
# children = [
# #(Text "\n "),
# #(Element:0xe178 {
# name = "user",
# children = [
# #(Text "\n "),
# #(Element:0xe308 { name = "name", children = [ #(Text "admin")] }),
# #(Text "\n "),
# #(Element:0xe538 { name = "password", children = [ #(Text "0mni")] }),
# #(Text "\n "),
# #(Element:0xe768 { name = "user", children = [ #(Text "\n")] }),
# #(Text "\n")]
# })]
# })]
# })
Parse a XML file:
doc = html_open("data.xml")
# => #<Nokogiri:XML:::Document:...>
Searching an XML document using XPath:
users = doc.search('//user')
# => [#<Nokogiri::XML::Element:...>, ...]
admin = doc.at('//user[@name="admin"]')
# => #<Nokogiri::XML::Element:...>
Build a XML document:
doc = xml_build do
playlist {
mp3 {
file { text('02 THE WAIT.mp3') }
artist { text('Evil Nine') }
track { text('The Wait feat David Autokratz') }
duration { text('1000000000') }
}
}
