Re: xpath - check for no content

I have to transform this into xsl:fo !
so, i do really NEED the additional break here!
background is- i am tranforming a Lotus Notes XML Export into a PDF
Dokument.
Some linbreaks and Paragraphs don't "get through" my templates at the
moment.
I am trying to figure out what's wrong or try to find a workaround, so that
the output looks like the Notes document.

I will try to see if your hints get me any further.
Thanks,
Sascha

Meaning that there is no output text or so inbetween.

In your example below, you do have text in between ... you have text nodes
comprised only of white-space characters.

example:
<run>
<font size="17pt" style="bold" name="Arial" color="red"/>
<break/>
</run>

I tried...

If the white-space *is* significant, just check the value of the current

node:

<xsl:if test=". = ''">

If the white-space *isn't* significant, trim leading and trailing just in
case the input was "lazily" empty:

<xsl:if test="normalize-space(.)=''">

Note this is a common problem where users *think* an element is empty, but
they've inserted a new-line to make the indentation look nice, not
realizing they no longer have an empty element.

I hope this helps.
