Steve Rowe updated SOLR-6856:
-----------------------------
Attachment: SOLR-6856.patch
I noticed when using {{DefaultHtmlMapper}} that the {{<br/>}} tag causes the
string "none\n" to show up in the catch-all {{content}} field Tika produces,
e.g. for
{code:xml}
<p>distinct<br/>words</p>
{code}
the following is extracted in the catch-all field:
{noformat}
distinctnone
words
{noformat}
I suspect this is a Tika bug, but I didn't track down why this happens.
I addressed this problem by copy/pasting {{IdentityHtmlMapper}} into a nested
class of {{ExtractingDocumentLoader}} and overriding {{mapSafeElement(String
name)}} to return {{null}} when {{name}} is {{br}} - this causes Tika to not
output the "none\n" string in the catch-all field.
I noticed that {{DefaultHtmlMapper}} excludes {{<SCRIPT>}} and {{<STYLE>}} tags
and their content, while {{IdentityHtmlMapper}} does not. I thought I would
need to also address this, because a general-purpose HTML extraction facility
should not include that {{<SCRIPT>}} or {{<STYLE>}} content. But apparently
Tika handles exclusion of these tags and their content at some location other
than the {{HtmlMapper}} - even when using {{IdentityHtmlMapper}}, no
start-element events are created for these tags. Nevertheless, I added a test
to make sure that {{<SCRIPT>}} and {{<STYLE>}} content is not extracted.
I added a new test to more fully demonstrate that {{xpath}} handling works
properly.
I think it's ready to go. I'm running all Solr tests now.
