如何通过Array获取所有文本 [英] How to get all text by Array

问题描述

数组可获取所有文字

 < p ng-if =！me.adminclass =sv ng-binding ng-scopeng-repeat =x in user.groups | orderBy > NASS InfoPass计划程序< / p> 
 
< p ng-if =！me.adminclass =sv ng-binding ng-scopeng-repeat =x in user.groups | orderBy> NASS Adjudications Scheduler< ; / p> 
  

如何使用 class =sv ng-binding ng-scope

使用 .nokogiri.org /rel =nofollow> Nokogiri 您可以将文本解压缩为

  require'nokogiri '
 
＃假设您将HTML文本存储在变量html中
 html =<< EOF 
< p ng-if =！me.admin类=sv ng-binding ng-scopeng-repeat =x in user.groups | orderBy> NASS InfoPass Scheduler< / p> 
< p ng-if =！me.adminclass =sv ng-binding ng-scopeng-repeat =x in user.groups | orderBy> NASS Adjudications Scheduler< / p& r< / p> 
 EOF 
 
 doc = Nokogiri :: HTML（html）
p doc.css（'。sv.ng-binding.ng-scope'）。map（&; text ）
＃=> [NASS InfoPass Scheduler，NASS Adjudications Scheduler] 
  




Array to get all text

<p ng-if="!me.admin" class="sv ng-binding ng-scope" ng-repeat="x in user.groups | orderBy">NASS InfoPass Scheduler</p>

<p ng-if="!me.admin" class="sv ng-binding ng-scope" ng-repeat="x in user.groups | orderBy">NASS Adjudications Scheduler</p>

How can I use class="sv ng-binding ng-scope" as a Array to get text?

解决方案

With Nokogiri you can extract the text as

require 'nokogiri'

# suppose you store your HTML text in variable `html'
html = <<EOF
  <p ng-if="!me.admin" class="sv ng-binding ng-scope" ng-repeat="x in user.groups | orderBy">NASS InfoPass Scheduler</p>
  <p ng-if="!me.admin" class="sv ng-binding ng-scope" ng-repeat="x in user.groups | orderBy">NASS Adjudications Scheduler</p>r</p>
EOF

doc = Nokogiri::HTML(html)
p doc.css('.sv.ng-binding.ng-scope').map(&:text)
#=> ["NASS InfoPass Scheduler", "NASS Adjudications Scheduler"]
