Is there any particular reason you have to use XSLT 1.0? This kind of thing
is much easier in 2.0. It more-or-less reduces to
replace(@xlink:href, '\.xml$', '.html')

Subject: [xsl] Conditional String Substitution
Greetings,
I need to do some string manipulation of an attribute value
using XSLT.
I need to look at the value of the attribute "href" and
determine if it ends in the suffix ".xml"
If so then I need to replace the ".xml" suffix with a ".html" suffix.
I got it to work using a pretty convoluted set of XPath
expressions in conjunction with xsl:if but I think that I am
missing something...
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
