Jsoup offers ways to fetch web pages and parse them from tag soup into a proper hierarchy. With tags and bits of tags floating around all over the place, this kind of document became known as Tag Soup, hence the name “jsoup” for the Java library. Misplaced tags like a inside the of a document.Mis-nested tags like This is mis-nested.Web browsers are therefore obliged to cope with: Good for them - this lowers the barrier for contribution on the web and makes it more resilient for all of us.
The WHATWG, who design HTML, have consistently decided that compatibility with previous versions of HTML and with existing web pages is more important than making sure that all documents are valid XML. At the end there is a small app which deals with real-world HTML. You’ll see how to parse valid (and invalid) HTML, clean up malicious HTML, and modify a document’s structure too. To adopt the flexible and stylish attitude of web browsers, you really need a dedicated HTML parser, and in this post I’ll show how you can use jsoup to deal with the messy and wonderful web. Some non-XML constructs are perfectly valid HTML and admirably, browsers just cope with it. People open tags without closing them, they nest tags wrongly, and generally commit all kinds of XML faux pas. The problem with this is that an awful lot of the HTML in the world is not valid XML. The author of that now-infamous text managed to recover from their distress enough to suggest using an XML parser (before, presumably, collapsing into the void). Have you tried using regular expressions? It won’t end well. Perhaps you are extracting data from a website that doesn’t have an API, or allowing users to put arbitrary HTML into your app and you need to check that they haven’t tried to do anything nasty? If your hosting also is blocking fsockopen() you might be out of luck.So, you need to parse HTML in your Java application. I realize you didn't want a PHP proxy solution, I think you might have no other choice. $fp = fsockopen($server, 80, $errno, $errstr, 30)
I was surprised to find they did NOT block the use of sockets, here's my workaround: $server = "$path = "/path/index.html" I don't think you can since you're trying to fetch something that is not JSONP.Īlso, you say your host blocks fopen(), I used to be on a hosting where they did the same. You updated your question saying you prefer a pure javascript solution. Your browser might not allow you to do this though. Either by calling a local php script making a file_get_contents() and returning it the the page, or directly calling an external URL. Short question, short answer: You probably want to play around with some Ajax.
