This can be accomplished with a single XPath 1.0 expression:
concat(substring(@x,
1,
string-length(@x)
-4
*
(substring(@x, string-length(@x)-3) = '.xml')
),
substring('.html',
1
div
(substring(@x, string-length(@x)-3) =
'.xml')
)
)
I picked the first parameter of the concat apart and I understand how
it works.
When I try to isolate the second parameter:
substring('.html',1 div(substring(@href, string-length(@href)-3)
= '.xml'))
My transformer won't parse it. Oddly, it works fine when imbedded in
your example.
Can you explain how it works?
Thanks,

Greetings,
I need to do some string manipulation of an attribute value using
XSLT.

Is there a more straight forward way of accomplishing this?
Example(s):
<xsl:template match="thredds:catalogRef">
<xsl:variable name="href" select="./@xlink:href" />
<xsl:variable name="linkSuffix"
select="substring($href,string-length($href) - 3)" />
<xsl:variable name="linkBody"
select="substring($href,1,string-length($href) - 4)" />
<xsl:if test="$linkSuffix='.xml'">
<xsl:value-of select="$indent"/><a
href="{concat($linkBody,'.html')}" ><xsl:value-of select="./
@xlink:title"/>
/</a>
</xsl:if>
<xsl:if test="not($linkSuffix='.xml')">
<xsl:value-of select="$indent"/><a href="{$href}"
><xsl:value-of
select="./@xlink:title"/> /</a>
</xsl:if>
</xsl:template>
I used a bunch of variables in the example simply to make it more
readable,
the example could be condensed to:
<xsl:template match="thredds:catalogRef">
<xsl:if test="substring(./@xlink:href,string-length(./
@xlink:href) -
3)='.xml'">
<a
href="{concat(substring(./@xlink:href,1,string-length(./
@xlink:href) -
4),'.html')}" ><xsl:value-of select="./@xlink:title"/> /</a>
</xsl:if>
<xsl:if
test="not(substring(./@xlink:href,string-length(./@xlink:href) -
3))">
<a href="{./@xlink:href}" ><xsl:value-of
select="./@xlink:title"/> /</a>
</xsl:if>
<br/>
</xsl:template>
Thanks!
Nathan
