Subject: Re: [xsl] Conditional String Substitution From: Nathan Potter <ndp@xxxxxxxxxxxxxxxxxxxx> Date: Fri, 25 Apr 2008 21:15:17 -0700 |
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...
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')
)
)

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!
