I think you can use existing ExtractingRequestHandler to do the job,
i.e. add child entity to your DIH metadata

<dataSource type="JdbcDataSource" name="db" ... />
<dataSource type="URLDataSource" name="solr" />
<entity name="metadata" query="select id, title, url from metadata"
dataSource="db">
    <entity processor="PlainTextEntityProcessor" name="content"
url="http://localhost:8983/solr/update/extract?extractOnly=true&wt=xml&indent=on&stream.url=${metadata.url}"
dataSource="solr">
        <field column="plainText" name="content"/>
    </entity>
</entity>

That's not working example, just basic idea, you still need to
uri_escape ${metadata.url} reference probably using some transformer
(regexp, javascript?) and extract file content from ERH xml response
using xpath and probably do some html stripping.

HTH,
Alex
