   • What are the pros and cons of the leading Java HTML parsers?

     Top Answer

     Answered Jun 20, 2020 · 232 votes

     General

     Almost all known HTML parsers implements the W3C DOM API (part of the JAXP API, Java API for XML processing) and gives you a org.w3c.dom.Document

     back which is ready for direct use by JAXP API. The major differences are usually to be found in the features of the parser in question. Most parsers are to a certain degree forgiving and lenient with non-wellformed HTML ("tagsoup"), like JTidy, NekoHTML, TagSoup and HtmlCleaner. You usually use this kind of HTML parsers to "tidy" the HTML source (e.g. replacing the HTML-valid <br> by a XML-valid <br />), so that you can traverse it "the usual way" using the W3C DOM and JAXP API.

     The only ones which jumps out are HtmlUnit and Jsoup.

     HtmlUnit

     HtmlUnit provides a completely own API which gives you the possibility to act like a webbrowser programmatically. I.e. enter form values, click elements, invoke JavaScript, etcetera. It's much more than alone a HTML parser. It's a real "GUI-less webbrowser" and HTML unit testing tool.

     Jsoup

     Jsoup also provides a completely own API. It gives you the possibility to select elements using jQuery-like CSS selectors and provides a slick API to traverse the HTML DOM tree to get the elements of interest.

     Particularly the traversing of the HTML DOM tree is the major strength of Jsoup. Ones who have worked with org.w3c.dom.Document know what a hell of pain it is to traverse the DOM using the verbose NodeList

     and Node

     APIs. True, XPath

     makes the life easier, but still, it's another learning curve and it can end up to be still verbose.

     Here's an example which uses a "plain" W3C DOM parser like JTidy in combination with XPath to extract the first paragraph of your question and the names of all answerers (I am using XPath since without it, the code needed to gather the information of interest would otherwise grow up 10 times as big, without writing utility/helper methods).

     String url = "http://stackoverflow.com/questions/3152138";Document document = new Tidy().parseDOM(new URL(url).openStream(), null);XPath xpath = XPathFactory.newInstance().newXPath(); Node question = (Node) xpath.compile("//*[@id='question']//*[contains(@class,'post-text')]//p[1]").evaluate(document, XPathConstants.NODE);System.out.println("Question: " + question.getFirstChild().getNodeValue());-NodeList answerers = (NodeList) xpath.compile("//*[@id='answers']//*[contains(@class,'user-details')]//a[1]").evaluate(document, XPathConstants.NODESET);for (int i = 0; i < answerers.getLength(); i++) { System.out.println("Answerer: " + answerers.item(i).getFirstChild().getNodeValue());}-

     And here's an example how to do exactly the same with Jsoup:

     String url = "http://stackoverflow.com/questions/3152138";Document document = Jsoup.connect(url).get();-Element question = document.select("#question .post-text p").first();System.out.println("Question: " + question.text());-Elements answerers = document.select("#answers .user-details a");for (Element answerer : answerers) { System.out.println("Answerer: " + answerer.text());}-

     Do you see the difference? It's not only less code, but Jsoup is also relatively easy to grasp if you already have moderate experience with CSS selectors (by e.g. developing websites and/or using jQuery).

     Summary

     The pros and cons of each should be clear enough now. If you just want to use the standard JAXP API to traverse it, then go for the first mentioned group of parsers. There are pretty a lot of them. Which one to choose depends on the features it provides (how is HTML cleaning made easy for you? are there some listeners/interceptors and tag-specific cleaners?) and the robustness of the library (how often is it updated/maintained/fixed?). If you like to unit test the HTML, then HtmlUnit is the way to go. If you like to extract specific data from the HTML (which is more than often the real world requirement), then Jsoup is the way to go.

   • what is the use of "response.setContentType("text/html")" in servlet

     Top Answer

     Answered Jan 12, 2013 · 22 votes

     Content types are included in HTTP responses because the same, byte for byte sequence of values in the content could be interpreted in more than one way.(*)

     Remember that http can transport more than just HTML (js, css and images are obvious examples), and in some cases, the receiver will not know what type of object it's going to receive.

     (*) the obvious one here is XHTML - which is XML. If it's served with a content type of application/xml, the receiver ought to just treat it as XML. If it's served up as application/xhtml+xml, then it ought to be treated as XHTML.

     StringEscapeUtils from Apache Commons Lang:

     import static org.apache.commons.lang.StringEscapeUtils.escapeHtml;// ...String source = "The less than sign (<) and ampersand (&) must be escaped before using them in HTML";String escaped = escapeHtml(source);-

     For version 3:

     import static org.apache.commons.lang3.StringEscapeUtils.escapeHtml4;// ...String escaped = escapeHtml4(source);-

     An alternative to Apache Commons: Use Spring's HtmlUtils.htmlEscape(String input) method.

     Nice short method:

     public static String escapeHTML(String s) { StringBuilder out = new StringBuilder(Math.max(16, s.length())); for (int i = 0; i < s.length(); i++) { char c = s.charAt(i); if (c > 127 || c == '"' || c == '\'' || c == '<' || c == '>' || c == '&') { out.append("&#"); out.append((int) c); out.append(';'); } else { out.append(c); } } return out.toString();}

     Based on https://stackoverflow.com/a/8838023/1199155 (the amp is missing there). The four characters checked in the if clause are the only ones below 128, according to http://www.w3.org/TR/html4/sgml/entities.html

   • In Java how can I use html tags on System.out.println()

     Top Answer

     Answered Jul 13, 2014 · 1 votes

     Yes,you can do that!You will have to embed necessary formatting: For eg: In order to get your output to be bold, you need to do the following:

     System.out.println((char)27 +"[1m testing bold");

     The (char) 27 is an escape sequence, the [ is followed by a set of ; separated values for different formatting types (see below), followed by an m. You will need to play around with this.

     Some attributes:

     0 Normal (clear all) 1 bold 2 dim 4 underline 5 blink 7 reverse 8 blank 9 overstrike 22 normal intensity (cancel bold and blank) 24 underline off 25 blink off 27 reverse off 28 blank off 29 overstrike off 30 black 31 red 32 green 33 yellow 34 blue 35 magenta 36 cyan 37 white 40 black background 41 red background 42 green background

   • How to get the XPath of an element in HTML in java?

     Top Answer

     Answered Oct 13, 2018 · 0 votes

     SOLVED:

     I managed to get all things to work this way:

     String html = getTheHTMLSomeWay();-Document doc = Jsoup.parse(Jsoup.clean(html, "http://base.uri", Whitelist.relaxed().preserveRelativeLinks(true)));doc.outputSettings().escapeMode(EscapeMode.xhtml).syntax(Syntax.xml).charset(StandardCharsets.UTF_8);org.w3c.dom.Document document = $(doc.html()).document();System.out.println($(document).find("a[href='/your/relative/url']"));

     With Jsoup i can clean the HTML against all that boring unclosed tags, not allowed tags etc. Then i can escape all the unescaped characters (according to xhtml) and set the syntax to xml.

     That can give you a clean html code, usable with jOOX library.
