[jira] Issue Comment Edited: (TIKA-286) HtmlParser calls
characters() with post-body data before processing the terminating body
element.
[ https://issues.apache.org/jira/browse/TIKA-286?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12760026#action_12760026 ]

-------------------------------------------------------------
I think this is a known "bug" (or feature?) in nekohtml which does the HTML parsing!
This caused by nekohtml to "fix" wrong html documents (e.g. the nekohtml parser also adds missing element end tags and so on). I think, it does this because the html element is not allowed to contain text data. Because of this it tries to fix by adding the text to the body element. This is exactly the way, also browsers fix bad html (e.g. html without body at all and so on). Please not that nekohtml also adds e.g. missing body elements or html elements (e.g. if the html only contains block tags normally only allowed inside the body element).
If you do not want this, post a bug report at nekohtml.

> Key: TIKA-286
> URL: https://issues.apache.org/jira/browse/TIKA-286
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 0.4
> Reporter: Ken Krugler
> Priority: Minor
>
> Using this example data:
> {noformat}
> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
> "http://www.w3.org/TR/html4/strict.dtd">
> <html lang="en">
> <head>
> <meta http-equiv="content-type" content="text/html; charset=utf-8">
> <title>Untitled</title>
> <base href="http://newdomain.com">
> </head>
> <body>
> <a href="link" target="_blank">link1</a>
> <a href="http://domain.com/link" target="_blank">link2</a>
> </body>
> </html>
> {noformat}
> The handler's characters() method gets called with the following text
> Untitled
> \n\n
> link1
> \n
> link2
> \n\n
> \n
> \n
> The first six calls make sense to me.
> The last two calls (with a single \n) happen just before endElement("body") is called, and this is unexpected.
> From the offset in the buffer, passed to characters(), these are the return _after_ the </body> tag. If I put any number of returns in between the </body> and </html>, they all get passed to characters() before the endElement("body") call.
