PHP way of parsing HTML string
提问by ThomasReggi
I have a php string that contains the below HTML I am retrieving from an RSS feed. I am using simple pie and cant find any other way of splitting these two datasets it gets from <description>. If anyone knows of a way in simple pie to select children that would be great.
我有一个 php 字符串，其中包含我从 RSS 提要中检索的以下 HTML。我正在使用简单的馅饼，但找不到任何其他方式来拆分它从<description>. 如果有人知道用简单的馅饼来选择孩子的方法，那就太好了。
<div style="example"><div style="example"><img title="example" alt="example" src="example.jpg"/></div><div style="example">EXAMPLE TEXT</div></div>
to:
$image = '<img title="example" alt="example" src="example.jpg">';
$description = 'EXAMPLE TEXT';

$received_str = 'Your received html';
$html = str_get_html($received_str);
//Image tag
$img_tag = $html->find("img", 0)->outertext;
//Example Text
$example_text = $html->find('div[style=example]', 0)->last_child()->innertext;

// Create DOM from HTML string
$html = str_get_html('Your HTML here');
// Find all images
foreach($html->find('img') as $element)
echo $element->src . '<br>';
// Description
$description = $html->find('div[style=example]');

try using strip_tags:
尝试使用 strip_tags：
<?php
$html ='<div style="example"><div style="example"><img title="example" alt="example" src="example.jpg"/></div><div style="example">EXAMPLE TEXT</div></div>';
$html = strip_tags($html,'<img>');
// $html == '<img title="example" alt="example" src="example.jpg">'
?>
