The spaces that you get in your output are not being copied from the
input,
they are being generated by virtue of the rule that a single space is
inserted between adjacent atomic values delivered in the result of a
content
constructor. This space isn't inserted between a string and a node,
only
between two strings.
(The reason for this rule is primarily for the case where you are
generating
list-valued simple content, e.g. ("red", "blue", "green"). It's less
satisfactory when generating complex content. It means that you need
to
understand the rather subtle distinction between a string and a text
node:
<xsl:value-of select="'a'"/> outputs a text node, while <xsl:sequence
select="'a'"/> outputs a string. <xsl:copy-of/> produces whatever it
is
given, which in this case is a string. Text nodes are output without
generating separator spaces.)
I think that if you output a text node containing a single
space either
side
of the <a> element, you will get the required effect. You can do this
with
<xsl:text> </xsl:text>

Subject: [xsl] Mistake in tokenizing under Saxon 8.2
Hello,
I presume that I have made a mistake somewhere in the stylesheet
when
using the tokenize function under Saxon 8.2 - for some reason I am
loosing the whitespace chars around the matched regular expression.
For example, the following pattern:
text text [link,alt,link_text] text
should be transformed to:
text text <a href="link" alt="alt">link text</a> text
BUT
I am loosing the whitespasce characters around the <a> as follows:
text text<a href="link" alt="alt">link text</a>text
^
^
Why is this please? All the other whitespace chars are copied OK,
even
though I am tokenising on whitespace.
If I use a in the stylesheet to compensate for the
loss, it adds
two spaces, not one, which is wierd, so this is not currently a
viable
solution.
Any input appreciated!
Many thanks,
Nic.
