Hello Mr. Kay,
Please pardon me, because my opinion is different
from yours. You have refered an Erratum section (E30).
Its not provided in the spec
URL(http://www.w3.org/TR/xslt). I cannot find it. Can
you please provide the URL?
Every W3C specification provides a link to the errata in the introduction to
the spec: see the "Status of this Document" section. For XSLT 1.0 it's at
http://www.w3.org/1999/11/REC-xslt-19991116-errata/
As I said, you only really need the erratum to understand the rules in cases
when both strip-space and preserve-space are present. In simple cases you
get the same result from the original text:
For source documents, the set of whitespace-preserving element names is
specified by xsl:strip-space and xsl:preserve-space top-level elements.
These elements each have an elements attribute whose value is a
whitespace-separated list of NameTests. Initially, the set of
whitespace-preserving element names contains all element names. If an
element name matches a NameTest in an xsl:strip-space element, then it is
removed from the set of whitespace-preserving element names. If an element
name matches a NameTest in an xsl:preserve-space element, then it is added
to the set of whitespace-preserving element names.
You are saying, for the example XML -
<pre>
<b>bold</b>
<i>italic</i>
</pre>
The first condition is true (i.e. The element name of
the parent of the text node is in the set of
*whitespace-preserving element names*).
Whereas, whitespace-preserving element names *is
specified by* xsl:strip-space and xsl:preserve-space
elements (given in Erratum E30).
Is'nt my understanding therefore right?
I don't know what your understanding is, but in the absence of
xsl:strip-space, all these elements are whitespace-preserving and the <pre>
element therefore has 5 children.
