I am still catching up old threads...

Ok. It would be nice if we could solve this in a way that doesn't
require to much writing for the template author. Turning on and of
whitespace skipping for all instructions for those who need formated
output isn't that attractive.
XSLT processors gives at least somewhat reasonable output compared to
what JXTG does. Anyone who knows what kind of rules XSLT-processor
uses for whitespace processing around instructions?
Yep. And for the sake of consistency and learning simplicity, it would
be good to use the same rules (see [1]).
The default behaviour is different for the XSLT program itself (i.e. the
template in JXTG) and the input document (which has no JXTG equivalent).
XSLT keeps a text node in the stylesheet if:
- the text node containes at least one non-whitespace character,
- the text node's parent element is <xsl:text>,
- the closest ancestor having an "xml:space" attribute has the value
"preserve" for this attribute (this attribute is kept in the output)
The <xsl:preserve-space> and <xsl:strip-space> instructions only apply
to the input document. I guess this difference is because the stylesheet
writer is supposed to know what it writes whereas input documents can
come from any source.
Again I don't dispute that there could be a need for explicit
whitespace skipping. But I would prefer if we could find a less
verbose way to get reasonable default whitespace processing for macros.
+1000! And IMO the XSLT way is this "reasonable default whitespace
processing" as it simply removes all whitespace nodes used for
indenting, which are mostly those that are annoying us.
And which are those? How would you like to differentiate what is a
"program" and what is "data" when they are both mixed in single
document? Example:
<jx:forEach var="elem" items="${elems}">
<elem>
<jx:formatDate value="${elem.date}"/>
</elem>
</jx:forEach>
What should the output look like?
A question though: what would be the difference between <jx:text> and
<jx:out>?
