[jira] [Commented] (TIKA-914) Invalid self-closing title tag when
parsing an RTF file
[ https://issues.apache.org/jira/browse/TIKA-914?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13270142#comment-13270142 ]
Ken Krugler commented on TIKA-914:
----------------------------------
I generated XHTML 1.0 (Strict) and XHTML 1.1 documents with <title/> tags, and they both passed validation (with BBEdit's built-in validator, and xmllint).
So it's possible that there's stricter validation I should be doing, but on the surface this looks like the case of valid-but-uncommon XHTML that causes a problem for Chrome.
If so, then this means that Tika should be changed to avoid generating <title/> tags, but it's more of an enhancement than a bug fix.

> Key: TIKA-914
> URL: https://issues.apache.org/jira/browse/TIKA-914
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 1.1
> Environment: Reproduced on Linux and Windows
> Reporter: Nicolas Guillaumin
> Priority: Minor
> Labels: rtf
> Attachments: test.rtf
>
>
> When parsing an RTF file with an empty TITLE metadata, the resulting HTML contains an self-closing title tag:
> {code}
> $ java -jar tika-app-1.1.jar -h test.rtf
> <html xmlns="http://www.w3.org/1999/xhtml">
> <head>
> <meta name="Content-Length" content="830468"/>
> <meta name="Content-Type" content="application/rtf"/>
> <meta name="resourceName" content="test.rtf"/>
> <title/>
> </head>
> [...]
> {code}
> I believe self-closing tags are not valid in XHTML, according to http://www.w3.org/TR/xhtml1/#C_3 (However there's no XHTML doctype generated here, just a namespace...). Anyway this causes some browsers like Chrome to fail parsing the HTML, resulting in a blank page displayed.
> The expected output would be a non self-closing empty tag: {{<title></title>}}
