duplicate w:bookmarkStart names cause duplicate fo ids

[jeromyevans]

Hi,
I've encountered a situation where a human-generated Word Document contains multiple bookmarks with the same name. This causes a duplicate ID error in the generated FO when attempting to transform it to PDF.

The extracted fragment of flat opc xml may look like this:

Code: Select all

<w:bookmarkStart w:id="1" w:name="d0e124"/>
<w:bookmarkEnd w:id="1"/>
...
<w:bookmarkStart w:id="0" w:name="d0e124"/>
<w:bookmarkEnd w:id="0"/>

When this document is transformed to FO for PDF the XSLT generates two fo:inline's with the same id:

Code: Select all

<fo:inline id="d0e124"/>

because the XSTL uses the name attribute as id:

Code: Select all

<xsl:template match="w:bookmarkStart" >
...
<fo:inline id="{@w:name}/>
...

I've worked-around this by overriding the XSTL in the classpath, but is this:
- an error in the word document? (i.e. should not allow duplicate names)
- an error in generation of the ID of the inline element? (i.e. not considering duplicate names)

In the sample document the two empty bookmarks are descendants of the same table.
(<w:tbl><w:tr><w:tc><w:p><w:bookmarkStart>)
