Looking for help trimming first 10 characters off the title of RSS feed

Question

I'm trying to write some xsl to style an RSS feed. The problem I'm running into is that I need to trim the first 10 characters off the title of each item and I can't get it to work.

<?xml version="1.0" encoding="ISO-8859-1"?> 
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/rss">
<ul>
<xsl:for-each select="channel/item">
<li><strong><xsl:value-of select="title"/>
</strong>
<a href="{link}">More</a></li>
</xsl:for-each>
</ul>
</xsl:template>

<xsl:template name="trimtitle">
<xsl:param name="string" select="." />
<xsl:if test="$string">
<xsl:text>Foo</xsl:text>
<xsl:call-template name="trimtitle">
<xsl:with-param name="string" select="substring($string, 10)" />
</xsl:call-template>
</xsl:if>
</xsl:template>

<xsl:template match="title">
<xsl:call-template name="title" />
<xsl:value-of select="." />
</xsl:template>


</xsl:stylesheet>

I'm sure I'm missing something basic, so any direction or assistance would be appreciates

Answer 1

I think you should write your substring function as this:

substring($string,1, 10)

Look at here

Answer 2

What are you doing in your trimtitle template? Why are you calling trimtitle recursive..?

The easiest way to show a trimmed string is with:

<xsl:value-of select="substring(title,0,10)"/>
