NOTE: edited by @drachenstern, and I don’t mind removing my answer on account of this. The OP is Russian (I believe) Ukrainian (with my apologies) and is having an ESL issue describing his problem. Between the two HRs is his original post.
order that would make getElementsByTagName (“s”); and give value = ‘2d331be47563423424abdb7fe2eee6401c7b00417’
my string:
<html>
<head>
<meta http-equiv='content-type' content='text/html; charset=windows-1251' />
</head>
<body onload="try { document.getElementById('l').submit(); } catch(e) { document.getElementsByTagName('form')[0].submit(); }">
<form id='l' method='post' action='http://vkontakte.ru/login.php'>
<input type='hidden' name='s' value='2d331be47563423424abdb7fe2eee6401c7b00417' />
<input type='hidden' name='op' value='slogin' />
<input type='hidden' name='redirect' value='1' />
<input type='hidden' name='expire' value='0' />
<input type='hidden' name='to' value='' />
</form>
</body>
</html>
I need Convert String to DOM model order that would make parsing
I write this is my String in Java!
String mystr = "<html....</html>";
Russian – “У меня есть строка в JAVA она содержит в себе html файл(страницу сайта). Мне нужна функция которая достанет value в input. Я знаю что это можно прекрасно сделать через DOM модель, но у меня не получается это сделать.”
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
InputSource is = new InputSource( new StringReader( body ) );
Document d = builder.parse( is );
String ss = d.getElementById("s").getNodeValue(); //- null
He understands the way to parse for an element in Javascript is via something like getElementsByTagName('s'); and he wants to find the equivalent way to do this in Java. He doesn’t know what library he needs. For what it’s worth, I don’t write Java either. He can only explain one metaphor with another tho.
Google translates his Russian request as:
I have a string in JAVA it contains
the html file (page). I need a
function that would get value in the
input. I know that this can be done
well through the DOM model, but I did
not get to do it.
If your HTML string will not be any more complicated than this, then the easiest solution is just to parse with a Regular Expression, like
