Xsl:strip-space and xsl:preserve-space (XSLT 2.0)

Discussion:

In my stylesheet, I am stripping all the spaces, new line character while
using <xsl:strip-space elements="*"/> which works perfectly as desired.

But now I've come across the requirement where I need to preserve spaces
between the tags in few specific elements generally the punctuations(see
below example) I tried to use the <xsl:preserve-space> to sort out this
issue but doesn't seems to be working and "xsl:strip-space" seems to
overcoming the effect of "xsl:preserve-space" effects. Can we use both to
get their respective effects or simply they cannot be used together?

Below is how they looks in my stylesheet:

Snippet
=======

<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:fn="http://www.w3.org/2005/xpath-functions">

<xsl:strip-space elements="*"/>

<xsl:preserve-space elements="element1 element2"/>

<xsl:output encoding="UTF-8" indent="no" media-type="text/xml"
method="xml"/>

--------------
--------------
--------------
--------------
--------------

</xsl:stylesheet>

Example:

<element1><surname>Dajnoki</surname>, <givenname>K.</givenname>
(<year>2002</year>) <article-title>XXXXX YYYY</article-title>.
<journal-title>ZZZZZZ XXXX</journal-title>
<first-page>43</first-page>–<last-page>46</last-page>.</element1>

Note: Spaces between the tags with any punctuation appears correctly (like
in <surname>Dajnoki</surname>, <givenname>K.</givenname>) but fails in case
of a single space between tags > < (for instance in </journal-title>
<first-page> and results into the </journal-title><first-page> )

Below is how I have defined template for "element1"

<xsl:template match="element1">
<xsl:apply-templates/>
</xsl:template>

Any suggestion would be an immense help.

Best,

It's microsoft's xml parser that has an "optimisation" in that it
removes all white sppace nodes by default and does this at xml parse
time, before xslt or any other process sees the result, so you can not
preserve the spaces, they have already gone.

The parser has a preserveWhitespace property that you can set to true
before parsing which will make the parser conform to the xml spec and
report these spaces, but I don't know if xml spy gives you an interface
to setting that property.

I believe it's true that the AltovaXML processor always strips whitespace
nodes (or calls the MSXML parser in a way that strips them) and I'm not
aware of any way of changing this.

Pankaj,

You can force MSXML to preserve whitespace by adding
xml:space="preserve" to the root element of your document. Then your
original stylesheet should work as desired. Let me know if that works.

On second thought, your original stylesheet will have to change, because
<xsl:strip-space/> won't strip whitespace-only text nodes that have been
force-preserved using xml:space="preserve" (which will be true for all
whitespace in your document if you put that at the root element).

Instead of using <xsl:strip-space/> (and <xsl:preserve-space/>), you
could use a template rule that processes whitespace-only text nodes that
are not children of <element1> or <element2>:

<xsl:template match="*[not(self::element1 or
self::element2)]/text()[not(normalize-space())]"/>

The rule is empty and thus has the effect of "stripping" them from the
result.

Let me know if that works. :-)

I got a message off-list that suggested to me that I wasn't very clear
about this. To be clear, the template-rule approach below requires that
you have xml:space="preserve" in the source document to prevent MSXML
from stripping any whitespace. Of course, as a stylesheet writer, that
may not always be within your control. But one way or another, you need
to preserve whitespace, and I can only think of three ways to do that:

1. Use xml:space="preserve" in the source document,
2. Set the preserveWhiteSpace property to true in the MSXML API, or
3. Use a different XSLT processor.

A variation of #1 is to simply put xml:space="preserve" on all the
<element1> and <element2> elements, but that might not be as practical.

In my stylesheet, I am stripping all the spaces, new line character while
using <xsl:strip-space elements="*"/> which works perfectly as desired.

But have you confirmed that without this statement this is not
already happening?

You don't mention which processor you are using or what invocation
parameters you are using.

In XSLT 1.0 you could rely on the source document white-space-only
text nodes to be preserved (except when using Microsoft). In XSLT
2.0 you cannot rely on this, because the *invocation* of the XSLT
processor can change whether or not white-space-only text nodes in
source documents are preserved.

Note, for example, the invocation of Saxon has the following parameter:

-strip:all|none|ignorable

Here is an example where the white-space between "</journal-title>"
and "<first-page>" is shown to be stripped or preserved without
saying anything in the stylesheet about stripping:

T:\ftemp>type pankaj.xsl
<?xml version="1.0" encoding="US-ASCII"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">

<xsl:output method="text"/>

</xsl:stylesheet>
T:\ftemp>type pankaj.xml
<element1><surname>Dajnoki</surname>, <givenname>K.</givenname>

But now I've come across the requirement where I need to preserve spaces
between the tags in few specific elements generally the punctuations(see
below example) I tried to use the <xsl:preserve-space> to sort out this
issue but doesn't seems to be working

Perhaps that is because the data model for your document, as created
by your stylesheet processor, is already stripping the
white-space-only text nodes before your stylesheet is invoked.

Post by Pankaj Chaturvedi
and "xsl:strip-space" seems to
overcoming the effect of "xsl:preserve-space" effects. Can we use both to
get their respective effects or simply they cannot be used together?

They can be used together.

Consider the following examples where, in pankaj2.xsl all elements
are having their white-space-only text nodes stripped with
<xsl:strip-space/> but in pankaj3.xsl there is the override with
<xsl:preserve-space/>:

T:\ftemp>type pankaj2.xsl
<?xml version="1.0" encoding="US-ASCII"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">

<xsl:strip-space elements="*"/>

<xsl:output method="text"/>

</xsl:stylesheet>
T:\ftemp>saxon9 -strip:none pankaj.xml pankaj2.xsl
Dajnoki, K.
(2002) XXXXX YYYY.
ZZZZZZ XXXX43-46.
T:\ftemp>type pankaj3.xsl
<?xml version="1.0" encoding="US-ASCII"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">

<xsl:strip-space elements="*"/>

<xsl:preserve-space elements="element1 element2"/>

<xsl:output method="text"/>

</xsl:stylesheet>
T:\ftemp>saxon9 -strip:none pankaj.xml pankaj3.xsl
Dajnoki, K.
(2002) XXXXX YYYY.
ZZZZZZ XXXX
43-46.
T:\ftemp>

Note: Spaces between the tags with any punctuation appears correctly (like
in <surname>Dajnoki</surname>, <givenname>K.</givenname>) but fails in case
of a single space between tags > < (for instance in </journal-title>
<first-page> and results into the </journal-title><first-page> )

Stripping and preserving white-space-only text nodes do not impact
text nodes that are not white-space-only. When there is punctuation
the node is not white-space-only.

I hope this helps.

Ken> In XSLT 1.0 you could rely on the source document
Ken> white-space-only text nodes to be preserved (except when

Ken> because the *invocation* of the XSLT processor can change
Ken> whether or not white-space-only text nodes in source
Ken> documents are preserved.

Ken> Note, for example, the invocation of Saxon has the following
Ken> parameter:

Ken> -strip:all|none|ignorable

I can't see any justification for this in the XSLT 2.0 recommendation,
other than the caveat of how a source document is constructed is
outside the remit of the recommendation. That was always the case for
XSLT 1.0 too.

This switch is nothing to do with the Recommendation, which says processors
can do what they like. There are three common patterns of whitespace
handling: report all whitespace text nodes, report none, and report only
those in element-only content. People come to Saxon from other products and
complain that its default is different from the one assumed by their
stylesheet code; this switch allows you to emulate what your previous
processor did so you don't have to change your code.

And my point was that this is the same in XSLT 1.0.
