Michael McCandless commented on TIKA-712:
-----------------------------------------
OK I committed four new failing (disabled) test cases, showing that we
don't extract text elements inherited from master/layout slide.
I played around some more with the master layout/slides and I think I
know what we need to do for XSLF (but I have no idea for HSLF;
hopefully it's somehow "parallel"):
* We'll have to look at the inheritence from slide -> layout ->
master, so that a slide's text is the union of its actual text,
plus text from its slide layout, plus text from the master. The
files in the _rels dir link a slide to its slideLayout, and a
slideLayout to its slideMaster.
* For each text element on slideLayout and slideMaster, we must
check for the presence of the p:sp -> p:nvSpPr -> p:nvPr -> p:ph
element. For example, {{<p:ph type="body" idx="1"/>}}. The ph
stands for "place holder", and it seems to mean it's not really
rendered. When I manually edited the XML in my doc to insert a
p:ph on text I had added, and viewed that in PowerPoint, it indeed
stopped rendering it. So if p:ph is present we should skip that text.
I think that should work! But I don't know where/how to do this;
likely we need to do this first in POI? Should I open an issue there?
