How do I extract HTML content using Regex in PHP
I know, i know... regex is not the best way to extract HTML text. But I need to extract article text from a lot of pages, I can store regexes in the database for each website. I'm not sure how XML parsers would work with multiple websites. You'd need a separate function for each website.
In any case, I don't know much about regexes, so bear with me.
I've got an HTML page in a format similar to this
<html>
<head>...</head>
<body>
<div class=nav>...</div><p id="someshit" />
<div class=body>....</div>
<div class=footer>...</div>
</body>
I need to extract the contents of the body class container.
I tried this.
$patter开发者_Python百科n = "/<div class=\"body\">\(.*?\)<\/div>/sui"
$text = $htmlPageAsIs;
if (preg_match($pattern, $text, $matches))
echo "MATCHED!";
else
echo "Sorry gambooka, but your text is in another castle.";
What am I doing wrong? My text ends up in another castle.
*EDIT: ooohh... never mind, I found readability's code
You are matching for class="body" your document has class=body: you're missing the quotes. Use "/<div class=\"?body\"?>(.*?)<\/div>/sui".
