Subject [jira] [Commented] (LUCENE-5734) HTMLStripCharFilter end offset should be left of closing tags
Date Thu, 05 Jun 2014 22:28:01 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-5734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14019355#comment-14019355

Steve Rowe commented on LUCENE-5734:
------------------------------------

bq. FYI it behaves as I expect if after hello is an XML entity such as in this example: {{hello&amp;nbsp;}}

I should point out that HTMLStripCharFilter only accepts the named character entities defined
in [the HTML 4.0 spec|http://www.w3.org/TR/REC-html40/sgml/entities.html], which happens to
include the predefined XML entities ({{&amp;gt;}}, {{&amp;lt;}}, {{&amp;quot;}},
{{&amp;apos;}}, and {{&amp;amp;}}).  {{&amp;nbsp;}} is specifically *not* an XML
entity, at least not as understood by HTMLStripCharFilter.  I mention this only to point out
that HTMLStripCharFilter doesn't parse XML for entity declarations, and will not honor them
if they appear.

>             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&nbsp;{noformat}
The end offset immediately follows the 'o'.
