从HTML标签中提取数据[自动获取开始和结束标签] - Extract data from HTML tags [ Automatically get start and end tags ] by php

Extract data from HTML tags [ Automatically get start and end tags ] by php

想创建一个脚本，自动从html标签(开始和结束)中获取内容，并将其存储到数组中

的例子:输入:

$str = <p>This is a sample <b>text</b> </p> this is out of tags.<p>This is <p>another text</p>for same aggregate <i>tags</i>.</p>

输出:

$blocks[0] = <p>This is a sample <b>text</b> </p>
$blocks[1] = <p>This is <p>another text</p>for same aggregate <i>tags</i>.</p>
NB: the first block start with <p> so must be stop at </p>, the second block again start with <p> but it has another start and end paragraph[<p></p>] between this, and stop when find </p> . That means i want to put all of the data and inner tags between start and end tags.

我将尝试提供一个答案，虽然这个解决方案并没有给你你正在寻找什么，因为嵌套的<p>标记不是有效的HTML。使用PHP的DOMDocument，您可以像这样提取段落标记。

<?php
$test = "<p>This is a sample <b>text</b> </p> this is out of tags.<p>This is <p>another text</p>for same aggregate <i>tags</i>.</p>";
$html = new DOMDocument();
$html->loadHTML($test);
$p_tags = array();
foreach ($html->getElementsByTagName('p') as $p) {
    $p_tags[] = $html->saveHTML($p);
}
print_r($p_tags);
?>

由于无效的标记嵌套而向您抛出一些警告后，输出应该如下所示:

Array
(
    [0] => <p>This is a sample <b>text</b> </p>
    [1] => <p>This is </p>
    [2] => <p>another text</p>
)

您可以使用Simple Html Dom库来完成此操作。以下是示例。

require_once('simple_html_dom.php');    
$html = " <p>This is a sample <b>text</b> </p> this is out of tags.<p>This is <p>another text</p>for same aggregate <i>tags</i>.</p>";    
$html = str_get_html($html);    
$p = $html->find('p');
$contentArray = array();
foreach($p as $element)
    $contentArray[] = $element->innertext; //You can try $element->outertext to get the output with tag. ie. <p>content</p>
print_r($contentArray);

你的输出是这样的:

Array
(
    [0] => This is a sample <b>text</b> 
    [1] => This is 
    [2] => another text
)
