Re: [xsl] recursive loop in XSL stylesheet is failing

There is one tiny little bit that I want to change. On the output the 
categories start with a colon:
    02/10/2010;:George:Illness expenses:Pharmacy;Test Pharmacy, 
Oakland;-19.1;
How can I remove this leading colon from the list of categories?

I tried the following code without luck:

        <xsl:template match="Category">
                <xsl:variable name="pid" select="@ParentID"/>
                <xsl:for-each select="$c">
                        <xsl:apply-templates select="key('c', $pid)"/>
                </xsl:for-each>
                <xsl:variable name="parent" select="en"/>
                <xsl:if test="string($parent)">
                        <xsl:value-of select="$parent"/>
                        <xsl:text>:</xsl:text>
                </xsl:if>
        </xsl:template>

Thanks in advance,
George
