XSL - NewLine
Hello all,
I need to put manually new line in a pdf document and it has to be for
the @value field.
I know, to put a new line I should use a new block, but Is it possible
to put some kind of "\r\n" string into the value to format it?
<fo:block hyphenate="true" font-size="10pt" font-weight="bold">
<xsl:value-of select="@value"/>
</fo:block>
This XSL document is used to convert an XML document to PDF with either
FOP 0.20.5 or 0.93 used embedded in a java 5.0 code.
Thank you for your help.
Kind regards,
Miroslav Gregan

Hi Miroslav,
I used:
<xsl:value-of select="codepoints-to-string(13)" /><xsl:value-of
select="codepoints-to-string(10)" />
for generating csv files.

FWIW: I've always considered the insertion of empty blocks more like
a FO-hack, a way to trick the processor. Very useful trick, in some
cases though. I've seen especially creative use of it in combination
with conditional negative space-before or space-after (a Norman Walsh/
Docbook idea, IIRC)
OTOH, if you /can/ do without them --i.e. there are no properties
specified on the block, so it's only used to emulate HTML's <br />--
then it's always better not to use them. Reason is that the Java
object corresponding to a fo:block is fairly large, even for empty
blocks. The less of them, the better for the memory footprint.
On top of that, the XSL transform should become much, much simpler,
as it becomes only a matter of adding an attribute.
Cheers,
Andreas

Depends, maybe that isn't semantically correct for their data (it isn't
for ours either.)
For example, take something like an email body. It has multiple lines
so line breaks should be formatted as linebreaks in the output, but each
line shouldn't really be treated as a separate element since they occur
in the same chunk of content.
(We do our own breaking by substituting <fo:block/> elements into the
appropriate places before running through FOP, although it sounds like
this attribute to make linebreaks significant may be cleaner.)

Why would you store data with line breaks in an XML element attribute that
way in the first place?
Sounds like instead of havin <tag attribute="values with line breaks" /> you
should reformat your data to be more flexible such as something like:
<tag>
<attr_tag>value1</attr_tag>
<attr_tag>value2</attr_tag>
<attr_tag>value3</attr_tag>
</tag>
Just my $.02

Interesting. I use xsl-fo too little to be aware of that. Nice tip for
me as well, may save a lot of work ;)

As mentioned in previous responses you need to add the linefeed
characters to the value. However, in addition you need to set the
property linefeed-treatment="preserve" on the enclosing fo:block
otherwise the linefeeds in the text will be treated like / converted to
spaces and don't generate a line break.

Your question seemed to be about how to insert line breaks in XML. If
you want to introduce newlines in the rendered PDF, there is no use
whatsoever to use line breaks the way we explained to you, because this
is treated as whitespace and handled accordingly by FOP (or any xsl-fo
processor for that matter).
Most likely you just want to use <fo:block>...
I do not understand why you want an attribute to contain \r\n as it
whitespace has no influence on the rendering process. Perhaps you mean
it the other way around: your source document contains some attribute
with newlines in it and you want these newlines to be turned into
<fo:block />. This is then an XSLT question and the answer depends on
what version you use. In XSLT 2 you can do the following:
<xsl:for-each select="tokenize(@your-attribute, '\n')">
<fo:block><xsl:value-of select="." />
....etc
</xsl:for-each>
Your best bet for this kind of questions is the XSLT list at mulberry
tech's: http://www.mulberrytech.com/xsl/xsl-list/index.html.

Thanks you for your answers
Actually I afraid I did not ask my question clearly enough.
The @value which is the content of an XML File's element which contains
a String.
This String has to be formatted (a little bit if possible :-) ) with new
lines.
So that the text:
Mister T"NewLineChar"Hannibal Smith"NewLineChar"Looping
Where "NewLineChar" should be the expected character
After rendering FOP will look like in PDF format to:
Mister T
Hannibal Smith
Looping
Is it possible? Or should I find a way to use multiple blocks?
Thank you.
Miroslav

Just use:
<xsl:text> </xsl:text>
or
<xsl:text>
</xsl:text>
You can also add an entity to your doctype if you tend to use this kind
of newlines more often:
<!ENTITY newline "&#x0D;&#x0A;" >
and use it as follows:
<xsl:text>&newline;</xsl:text>
which will be rendered as a \r\n by the serializer. Of course, you could
also use an xsl:variable to do the same.
Why do you want a \r *and* a \n? Because if you output XML (which you
do: XSL-FO) the serializer will make sure that all \r\n will become \n.
Which means that
<xsl:text>
</xsl:text>
is semantically equivalent with:
<xsl:text>
</xsl:text>
which means that the newline entity definition will do exactly the same
when defined thus:
<!ENTITY newline "&#x0A;" >
(not so when you output as text, but that is another story)
If you *have* to have both the \r and the \n in the serialized output (I
have no idea why, I think you don't) then your only bet is XSLT 2.0
which allows you to put in late-serialization replacements with
xsl:character-map.
