wp14:sizeRelH within wp:anchor - supported in 2.7.1?

[rkamke]

Hello,

I have a XML part of a DOCX which in fact is a w:hdr. It contains a w:drawing with a wp:anchor. Nested in this anchor element I have several subelements: wp:simplePo, wp:positionH, wp:positionV, wp:extent, wp:effectExtent, wp:wrapTight, wp:docPr, wp:cNvGraphicFramePr, a:graphic (so far everything is fine), wp14:sizeRelH and wp14:sizeRelV.
The "Office Drawing Extensions to Office Open XML Structure Sepcification" - I found a version dated June 8, 2011 - suggests this structure being valid. Older sources (http://www.schemacentral.com/sc/ooxml/e-wp_anchor.html) suggest an error here.

docx4j 2.7.1 complains when parsing the XML part (text reformatted):
WARN (JaxbValidationEventHandler.java:80) - [ERROR] : unexpected element (uri:"http://schemas.microsoft.com/office/word/2010/wordprocessingDrawing", local:"sizeRelH").
Expected elements are
<{http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing}wrapTopAndBottom>,
<{http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing}docPr>,
<{http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing}wrapNone>,
<{http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing}wrapTight>,
<{http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing}simplePos>,
<{http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing}wrapThrough>,
<{http://schemas.openxmlformats.org/drawingml/2006/main}graphic>,
<{http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing}wrapSquare>,
<{http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing}extent>,
<{http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing}effectExtent>,
<{http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing}positionH>,
<{http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing}positionV>,
<{http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing}cNvGraphicFramePr>

I wonder whether docx4j 2.7.1 supports wp14:sizeRelH and wp14:sizeRelV after a:graphic within a wp:anchor. Can you give me some piece of advice how to cope with this situation?

Thank you,
Roland

Parsed in 0.020 seconds, using GeSHi 1.0.8.4

which traps UnmarshalException, and then preprocesses, effectively choosing the 2007 mc:AlternateContent presumed to be present (and dropping the wp14 stuff).

Perhaps you could include the relevant XML so we can see whether it ought to be handled by this logic.

Is the JaxbValidationEventHandler message you are seeing arising when you open the docx, or in the course of some other processing?
