Since you need to match content without including it in the result (must match name=” but it’s not part of the desired result) some form of zero-width matching or group capturing is required. This can be done easily with the following tools: Perl With Perl you could use the n option to loop line by … Read more
Native XML Extensions I prefer using one of the native XML extensions since they come bundled with PHP, are usually faster than all the 3rd party libs and give me all the control I need over the markup. DOM The DOM extension allows you to operate on XML documents through the DOM API with PHP … Read more
$url=”http://example.com”; $html = file_get_contents($url); $doc = new DOMDocument(); @$doc->loadHTML($html); $tags = $doc->getElementsByTagName(‘img’); foreach ($tags as $tag) { echo $tag->getAttribute(‘src’); }
You can use “<pre>(.*?)</pre>”, (replacing pre with whatever text you want) and extract the first group (for more specific instructions specify a language) but this assumes the simplistic notion that you have very simple and valid HTML. As other commenters have suggested, if you’re doing something complex, use a HTML parser.
Self plug: I have just released a new Java HTML parser: jsoup. I mention it here because I think it will do what you are after. Its party trick is a CSS selector syntax to find elements, e.g.: String html = “<html><head><title>First parse</title></head>” + “<body><p>Parsed HTML into a doc.</p></body></html>”; Document doc = Jsoup.parse(html); Elements links … Read more
Entire HTML parsing is not possible with regular expressions, since it depends on matching the opening and the closing tag which is not possible with regexps. Regular expressions can only match regular languages but HTML is a context-free language and not a regular language (As @StefanPochmann pointed out, regular languages are also context-free, so context-free … Read more
So that I can ask it to get me the content/text in the div tag with class=”container” contained within the body tag, Or something similar. try: from BeautifulSoup import BeautifulSoup except ImportError: from bs4 import BeautifulSoup html = #the HTML code you’ve written above parsed_html = BeautifulSoup(html) print(parsed_html.body.find(‘div’, attrs={‘class’:’container’}).text) You don’t need performance descriptions I … Read more
cleanText = strInputCode.replace(/<\/?[^>]+(>|$)/g, “”); Distilled from this website (web.achive). This regex looks for <, an optional slash /, one or more characters that are not >, then either > or $ (the end of the line) Examples: ‘<div>Hello</div>’ ==> ‘Hello’ ^^^^^ ^^^^^^ ‘Unterminated Tag <b’ ==> ‘Unterminated Tag ‘ ^^ But it is not bulletproof: … Read more
Create a dummy DOM element and add the string to it. Then, you can manipulate it like any DOM element. var el = document.createElement( ‘html’ ); el.innerHTML = “<html><head><title>titleTest</title></head><body><a href=”https://stackoverflow.com/questions/10585029/test0″>test01</a><a href=”test1″>test02</a><a href=”test2″>test03</a></body></html>”; el.getElementsByTagName( ‘a’ ); // Live NodeList of your anchor elements Edit: adding a jQuery answer to please the fans! var el = $( … Read more
