-----------------------------------
Summary: Less than sign within tag boundaries considered as start
of a new tag.
Key: TIKA-2928
URL: https://issues.apache.org/jira/browse/TIKA-2928
Project: Tika
Issue Type: Bug
Components: parser, server
Affects Versions: 1.22
Reporter: Desmond David
So I have been attempting to parse some (somewhat non-standard) HTML documents
using Tika and I have observed that if the document contains a less-than sign
(<) as part of a tag's body, Tika parses it as the start of a new tag and
eventually omits the rest of the text in the final document, up to the point
when the next newline is to be entered.
For example, consider the following HTML snippet:
{code:html}
<tr ><td > GFR<60 = Chronic Kidney Disease, GFR<15 = Kidney Failure
</td></tr><tr ><td ></td></tr><tr ><td > ENZYMES & BILIRUBIN</td></tr>{code}
The result is:
{code:java}
GFR
ENZYMES & BILIRUBIN
{code}
Here, the rest of the content after the first `GFR` gets omitted. Based on this
observation I think this means that the `<60` and it's subsequent characters
are getting interpreted as part of a tag, and since are getting ignored. Then
at some point, `</tr></td>` is encountered which short-circuits the execution
and starts processing the next line.
This behaviour was observed using both, the Tika App and the Tika Server.
I think expected behaviour should be that all text within data tags (p, td,
etc.) should be considered as raw text. Or at least Tika's behaviour should be
configurable to be allowed to do so.
