Subject [jira] [Commented] (TIKA-956) Embedded docs in Word doc are not inlined (text is always added to the end)
Date Sun, 05 Aug 2012 13:50:03 GMT

    [ https://issues.apache.org/jira/browse/TIKA-956?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13428851#comment-13428851

Jukka Zitting commented on TIKA-956:

Instead of the non-standard {{embedded}} attribute, it would be better to use a construct
like {{<div class="embedded" id="_NNNNNN">}} for this.  A code snipped like the following
should do the trick:

String id = "_" + field.getMarkSeparatorCharacterRun(r).getPicOffset();
AttributesImpl attributes = new AttributesImpl();
attributes.addAttribute("", "class", "class", "CDATA", "embedded");
attributes.addAttribute("", "id", "id", "CDATA", id);
handler.startElement(XHTML, "div", "div", attributes);

An even better approach would be to use something like {{<img src="embedded:..." alt="...">}}
or {{<object data="embedded:..." type="...">...</object>}}. See the {{XWPFWordExtractorDecorator}}
class for an example of how embedded images are handled in OOXML Word documents.

> You can see this with the recently added testWORD_embedded_pdf.doc
> (for TIKA-948): the "Bye Bye" text comes before the "Wer
> wjelrwoierj..." text from the embedded PDF, opposite of what you see
> when you open the doc with Word.
> Yet, the thumbnail images do seem to be extracted at the right place
> (inlined).
> This is because WordExtractor.java has a separate pass at the end to
> visit the embedded docs.
> Would it be possible to recurse into an embedded doc at the point when
> it's first encountered instead...?  Or maybe somehow correlate the
> images with their corresponding attachment (right now they are just
> named image1, image2, ...)?
