问题描述

这是我的代码:

<?php
    include('simple_html_dom.php');
    $html = file_get_html('http://www.google.com/search?q=BA236',false);
    $title=$html->find('div#ires', 0)->innertext;
    echo $title;
?>

它输出搜索BA236下的Google搜索页面的所有结果。

It outputs all result of the Google Search Page under the Search "BA236".

问题是我不需要所有这些信息,我需要的信息是在没有id或类或其他任何内容的div中。

The problem is I dont need all of them and the Information I need is inside a div that has no id or class or anything else.

我需要的div在第一个

The div I need is inside the first

<div class="g">

在页面上,所以也许我应该试试这样的内容:

on the Page, so maybe I should try something like this:

<?php
    include('simple_html_dom.php');
    $html = file_get_html('http://www.google.com/search?q=BA236',false);
    $title=$html->find('div[class=g], 0')->innertext;
    echo $title;
?>

但问题是,如果我加载页面, p>

But the Problem of that is, if I load the page it shows me nothing except this:

    $title=$html->find('div[class=g]')[0]->innertext;

推荐答案

我对您的代码进行了更改对于这个类:

I made a change to your code where I am searching for the class:

<?php
    include('simple_html_dom.php');
    $html = file_get_html('http://www.google.com/search?q=BA236',false);
    $e = $html->find("div[class=g]");
echo $e[0]->innertext;
?>

结果:

result:

British Airways Flight 236

Scheduled   departs in 13 hours 13 mins

Departure   DME 5:40 AM     —

Moscow  Dec 15

Arrival LHR 6:55 AM     Terminal 5

Departure   DME 5:40 AM     —

我用g类寻找div元素,然后打印出第一个元素'0'的计数

I looked for the div elements with class g then I printed the count of the first element '0'

$e = $html-> find ("div [class = g]");
echo $e [0]->innertext;

您的代码:

Your code:

<?php
    include('simple_html_dom.php');
    $html = file_get_html('http://www.google.com/search?q=BA236',false);
    $title=$html->find('div[class=g]')[0]->innertext;
    echo $title;
?>

不是('div [class = g],0') code>

('div [class = g]')[0]
