How can I use the HTML parser with Apache Tika in Java to extract all HTML tags?

Question

I download the tika-core and tika-parser libraries, but I could not find code examples for parsing HTML documents. I have to get rid of all the html tags of the webpage source. What can I do? How can I use Apache Tika code?

Answer 1

Do you need a text version of the html file? If so, all you need is something like:

InputStream input = new FileInputStream("myfile.html"); ContentHandler handler = new BodyContentHandler(); Metadata metadata = new Metadata(); new HtmlParser().parse(input, handler, metadata, new ParseContext()); String plainText = handler.toString(); 

A BodyContentHandler created without constructor arguments or with a character limit will capture the text (only) of the html body and return it to you.

You can also use Tika AutoDetectParser to parse any type of file, such as HTML. Here is a simple example:

  try { InputStream input = new FileInputStream(new File(path)); ContentHandler textHandler = new BodyContentHandler(); Metadata metadata = new Metadata(); AutoDetectParser parser = new AutoDetectParser(); ParseContext context = new ParseContext(); parser.parse(input, textHandler, metadata, context); System.out.println("Title: " + metadata.get(metadata.TITLE)); System.out.println("Body: " + textHandler.toString()); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (SAXException e) { e.printStackTrace(); } catch (TikaException e) { e.printStackTrace(); }
