Hello List,
I am using following template to display a
<br> tag after every 25th character of the string. But
that does not seem to work.
<xsl:template name="normaliseString">
<xsl:param name="releaselevel"/>
<xsl:variable name="temp"
select="substring($releaselevel,1,25)"/>
<xsl:value-of select="$temp"/>
<xsl:text><br> </xsl:text>
<xsl:if test="string-length($releaselevel) >25">
<xsl:variable name="temp2"
select="substring($temp,26,string-length($releaselevel))"/>
<xsl:value-of select="$temp2"/>
<xsl:call-template name="normaliseString">
<xsl:with-param name="releaselevel"
select="@temp2"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
any suggestion.
Hi,
You forgot to say why your template 'didn't seem to work' so I've had to
guess ;-) I think you just want the standard tail-recursive string
processing template. This involves ensuring the recursive part of the
template is the last operation in the template, allowing the compiler to
flatten the recursion into a set of if-elses (which is more memory
efficient).
<xsl:template name="normaliseString">
<xsl:param name="releaselevel"/>
<xsl:choose>
<xsl:when test="string-length($releaselevel) < 25">
<xsl:value-of select="$releaselevel"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="substring($releaselevel, 1, 25)"/>
<br/>
<xsl:call-template name="normaliseString">
<xsl:with-param name="releaselevel"
select="substring($releaselevel, 25)"/>
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
cheers
