Pascal Sancho commented on FOP-2520:
------------------------------------
All text nodes are processed by FOP, this is the correct behaviour.
If you want to discard spaces, you have to 1st do it at XSLT stage:
- avoid indentation
- do not add unwanted extra white spaces (including linefeed)
- etc.
At FOP stage, you may interact on white spaces using following FO properties:
- linefeed-treatment (http://www.w3.org/TR/xsl/#linefeed-treatment)
- white-space-treatment (http://www.w3.org/TR/xsl/#white-space-treatment)
- white-space-collapse (http://www.w3.org/TR/xsl/#white-space-treatment)
That said, Jira is not the right place to discuss about this.
either fop-users mailing list, or better XSLT/XSL-FO mailing lists, are more
appropriate.
Audience on such lists is larger.

> Project: FOP
> Issue Type: Bug
> Affects Versions: 2.0
> Reporter: Björn Kautler
> Attachments: empty space that should not be there.png
>
>
> If you use {{indexterm}} tags in DocBook, the DocBook XSL stylesheets
> generate empty {{fo:wrapper}} or {{fo:block}} elements with an {{id}}
> attribute. These elements take up visible space if processed with FOP. Using
> XEP, those empty tags do not consume any space.
> Here an example excerpt from a FO file in question and [attached|^empty space
> that should not be there.png] the result.
> {code:xml}
> <fo:block space-before.optimum="0.6em" space-before.minimum="0.4em"
> space-before.maximum="0.8em">
> <fo:wrapper id="N1004F"><!--table, customize columns--></fo:wrapper>
> <fo:wrapper id="N10056"><!--customize, table--></fo:wrapper>
> <fo:wrapper id="N1005D"><!--filter, table--></fo:wrapper>
> <fo:wrapper id="N10064"><!--table, filter--></fo:wrapper>You can customize
> most tables in the product. The configured table view is saved in your user
> profile and will be restored when you start the prouct the next time.
