jquery - Fast way to get specific data from HTML string using PHP

asked Jan 31, 2022 in Technique[技术] by 深蓝 (71.8m points)

I avoided a lot to come here share my problem. I have googled a lot and find some solutions but not confirmed. First I explain My Problem.

I have a CKEditor in my site to let the users post comments. Suppose a user clicks two posts to Multi quote them, the data will be like this in CKEditor

<div class="quote" user_name="david_sa" post_id="223423">
This is Quoted Text 
</div>

<div class="quote" user_name="richard12" post_id="254555">
This is Quoted Text 
</div>

<div class="original">
This is the Comment Text 
</div>

I want to get all the elements separately in php as below

user_name = david_sa
post_id = 223423;
quote_text = This is Quoted Text

user_name = david_sa
post_id = richard12;
quote_text = This is Quoted Text

original_comment = This is the Comment Text

I want to get the data in above format in PHP. I have googled and found the preg_match_all() PHP function near to my problem, that uses the REGEX to match the string patterns. But I am not confirmed that is it a legitimate and efficient solution or there is some better solution. If You have any better solution Please Suggest Me.

You can use DOMDocument and DOMXPath for this. It takes very few lines of code to parse HTML and extract just about anything from it.

$doc = new DOMDocument();
$doc->loadHTML(
'<html><body>' . '

<div class="quote" user_name="david_sa" post_id="223423">
This is Quoted Text 
</div>

<div class="quote" user_name="richard12" post_id="254555">
This is Quoted Text 
</div>

<div class="original">
This is the Comment Text 
</div>

' . '</body></html>');

$xpath = new DOMXPath($doc);

$quote = $xpath->query("//div[@class='quote']");
echo $quote->length; // 2
echo $quote->item(0)->getAttribute('user_name'); // david_sa
echo $quote->item(1)->getAttribute('post_id');   // 254555

// foreach($quote as $div) works as expected

$original = $xpath->query("//div[@class='original']");
echo $original->length;             // 1
echo $original->item(0)->nodeValue; // This is the Comment Text

If you are not familiar with XPath syntax then here are a few examples to get you started.
