Jukka Zitting resolved TIKA-730.
--------------------------------
Resolution: Won't Fix
Resolving as Won't Fix since in this case the WriteOutContentHandler class
works exactly as designed and documented.
Have you looked at the [Tika facade
class|http://tika.apache.org/0.10/api/org/apache/tika/Tika.html] that provides
a simplified API for extracting just the text content of a document as a String
or a Reader? That should be a better match for your use case than
WriteOutContentHandler.
> WriteOutContentHandler concatenates title tag and body text.

> Key: TIKA-730
> URL: https://issues.apache.org/jira/browse/TIKA-730
> Project: Tika
> Issue Type: Bug
> Components: general, parser
> Affects Versions: 0.9
> Reporter: Raimund Merkert
>
> I just noticed that the WriteOutContentHandler concatenates strings that it
> should not concatenate. I noticed this in case of a title tag which was
> combined with the first text in a body, e.g.:
> <head><title>a</title><head><body>b</body>
> results in "ab" and not "a b" (or something else with a break).
> Interestingly, "<p>a</p><p>b</p>" does get broken into separate words.
> I'm not aware of a better way to extract text only with an out-of-the-box
> tika.
> I've added a small unit test here:
> {code}
> package tika;
> import java.io.ByteArrayInputStream;
> import java.io.InputStream;
> import java.io.StringWriter;
> import java.nio.charset.Charset;
> import junit.framework.Assert;
> import org.apache.tika.parser.AutoDetectParser;
> import org.apache.tika.parser.ParseContext;
> import org.apache.tika.sax.WriteOutContentHandler;
> import org.junit.Test;
> public class WriteOutContentHandler_JUnit {
> private static final String HTML = "<!DOCTYPE html PUBLIC \"-//W3C//DTD
> XHTML 1.0 Transitional//EN\"
> \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\";>"
> + "<html
> xmlns=\"http://www.w3.org/1999/xhtml\";><head><title>title</title></head>
> <body>a</body></html>";
> public static String processStream(String str) throws Exception {
> InputStream in = new ByteArrayInputStream(str.getBytes(Charset
> .forName("UTF-8")));
> AutoDetectParser parser = new AutoDetectParser();
> ParseContext context = new ParseContext();
> org.apache.tika.metadata.Metadata m = new
> org.apache.tika.metadata.Metadata();
> StringWriter out = new StringWriter();
> WriteOutContentHandler ctHandler = new
> WriteOutContentHandler(out);
> try {
> parser.parse(in, ctHandler, m, context);
> return out.toString();
> } finally {
> out.flush();
> }
> }
> @Test
> public void testParse() throws Exception {
> String data = processStream(HTML);
> data = data.trim();
> System.err.println("Extracted:\n" + data);
> Assert.assertFalse(data.equals("titlea"));
> }
> }
> {code}
