Steve Rowe updated SOLR-6856:
-----------------------------
Attachment: SOLR-6856.patch
The {{<div>}} capture issue (also a mapping issue since there's nothing to map)
is that in Tika 0.6 (Solr 3.1 upgraded Tika from 0.4 to 0.8), a
{{DefaultHtmlMapper}} was introduced that only creates events for a subset of
HTML tags - when
http://tika.apache.org/1.7/api/org/apache/tika/parser/html/HtmlMapper.html#mapSafeElement(java.lang.String)
returns null (as it does for any non-mapped tags), its child content is
processed, but no event is created for the tag. {{HtmlParser}} uses
{{DefaultHtmlMapper}} if no {{HtmlMapper.class}} mapping is supplied with
{{ParseContext}}. Here's the 1.7 {{DefaultHtmlMapper.SAFE_ELEMENTS}}
definition, where the mappings are initialized:
[http://svn.apache.org/viewvc/tika/tags/1.7/tika-parsers/src/main/java/org/apache/tika/parser/html/DefaultHtmlMapper.java?view=markup#l33]
- no {{<div>}} in there.
The attached patch maps the {{HtmlMapper.class}} in {{ParseContext}} to
[{{IdentityHtmlMapper}}|http://tika.apache.org/1.7/api/org/apache/tika/parser/html/IdentityHtmlMapper.html],
which creates events for every HTML element. A new test is added to check
that elements including {{<div>}} are captured and mapped properly.
