It's a case for a recursive template:
<xsl:call-template name="trim">
<xsl:param name="in"/>
<xsl:choose>
<xsl:when test="substring($in, string-length($in), 1)=' ')">
<xsl:value-of select="$in"/>
</xsl:when>
<xsl:otherwise>
<xsl:call-template name="trim">
<xsl:with-param name="in"
select="substring($in, 1, string-length($in)-1)"/>
</
</

Subject: [xsl] Splitting a string on word boundaries
Hello all, I've got what I think is a simple problem but I
can't find a solution.
I am generating a RSS file and summarising the first 200
characters for the output.
The XML source <content> element contains only text (xs:string).
The XSL is:
<xsl:value-of
select="normalize-space(substring(content[not(@private)],1,200))"/>
This can often cause words to become truncated at the end. I
would much rather have a way to output say the first 30
words, rather than the first 200 characters.
The full xsl is available at
http://journal.the-i.org/xsl/rss091.xsl and > rss-imports.xsl
and the output is http://journal.the-i.org/rss091.xml
Thanks for any help :)
