Getting no text content from html

Hi all,

I'm just starting with tika and try to extract the text content of some
html. Unfortunately, I get no content at all.

This is my test method (in scala):

  def testHtml() {
    val html = "<html><body>my content</body></html>"
    val input = new ByteArrayInputStream(html.getBytes)
    val metadata = new Metadata
    val textHandler = new BodyContentHandler
    val parser = new HtmlParser
    parser.parse(input, textHandler, metadata);
    input.close();
    println("HTML Input: " + html)
    println("Title: " + metadata.get("title"))
    println("Author: " + metadata.get("Author"))
    println("content: " + textHandler.toString)
  }

Is there anything wrong here?

Thanx && cheers,
Martin

If the above was not explicit enough: textHandler.toString was empty.

Any help?

Thx && cheers,
Martin

Ok, probably it's enough just to depend on tika-parsers... :)

Great, with 0.4 it works, now I get the html content!

Just to mention it: I had to depend on
  org.apache.tika:tika-core
and
  org.apache.tika:tika-parsers
and was no longer able to just depend on org.apache.tika:tika to get
everything that's needed.

Thanx && cheers,
Martin

You're most likely hitting issue TIKA-210 [1] that's fixed in the 0.4 release.
