Get content within a html tag using php and replace it after processing

esafwan - you could use a regex expression to extract the content between the div (of a certain id).

I've done this for image tags before, so the same rules apply. i'll look out the code and update the message in a bit.

[update] try this:

<?php
    function get_tag( $attr, $value, $xml ) {

        $attr = preg_quote($attr);
        $value = preg_quote($value);

        $tag_regex = '/<div[^>]*'.$attr.'="'.$value.'">(.*?)<\\/div>/si';

        preg_match($tag_regex,
        $xml,
        $matches);
        return $matches[1];
    }

    $yourentirehtml = file_get_contents("test.html");
    $extract = get_tag('id', 'content', $yourentirehtml);
    echo $extract;
?>

or more simply:

preg_match("/<div[^>]*id=\"content\">(.*?)<\\/div>/si", $text, $match);
$content = $match[1];

If this is a simple replacement that does not involve parsing of the actual HTML document, you may use a Regular Expression or even just str_replace for this. But generally, it is not a advisable to use Regex for HTML because HTML is not regular and coming up with reliable patterns can quickly become a nightmare.

The right way to parse HTML in PHP is to use a parsing library that actually knows how to make sense of HTML documents. Your best native bet would be DOM but PHP has a number of other native XML extensions you can use and there is also a number of third party libraries like phpQuery, Zend_Dom, QueryPath and FluentDom.

If you use the search function, you will see that this topic has been covered extensively and you should have no problems finding examples that show how to solve your question.

<?php

    $content=file_get_contents("sample.html");
    $comment=explode("<!--content-->",$content);
    $comment=explode("<!--content-->",$comment[1]);
    var_dump(strip_tags($comment[0]));
?>

check this ,it will work for you
