David Smiley commented on LUCENE-5734:
--------------------------------------
FYI this triggered my interest because I'm trying to highlight XML.
Technically I'm not using Lucene/Solr's highlighter as I'm doing something
custom. I'm going to insert special demarcation markup into the source text at
the offsets that I find. My current work-around is to detect that the source
text has a closing element at the end offset, and then adjust for it if found.
Not too hard for me.
> HTMLStripCharFilter end offset should be left of closing tags

> Key: LUCENE-5734
> URL: https://issues.apache.org/jira/browse/LUCENE-5734
> Project: Lucene - Core
> Issue Type: Bug
> Components: modules/analysis
> Reporter: David Smiley
> Priority: Minor
>
> Consider this simple input:
> {noformat}
> <em>hello</em>
> {noformat}
> to be analyzed by HTMLStripCharFilter and WhitespaceTokenizer.
> You get back one token for "hello". Good. The start offset of this token is
> at the position of 'h' -- good. But the end offset is surprisingly plus one
> to the adjacent </em>. I argue that it should be plus one to the last
> character of the token (following 'o').
> FYI it behaves as I expect if after hello is an XML entity such as in this
> example: {noformat}hello {noformat} The end offset immediately follows
> the 'o'.
