Re: [Hypercontent-users] BreadCrumbs

[Alex V. <av...@co...>]

Hi Carl,
	I was able to duplicate the problem, and I was able to resolve it by  
replacing the use of the "//" axis with "descendant-or-self::".

e.g.

<xsl:template name = "breadcrumb">
    <xsl:param name = "item" select =  
"$navigation/nav-item[descendant-or-self::nav- 
item[@location=$sourceLoc]]"/>

    <xsl:call-template name = "breadcrumblink">
        <xsl:with-param name = "item" select = "$item"/>
    </xsl:call-template>

    <xsl:if test = "not($item/@location=$sourceLoc)">
        <xsl:text>
            >
        </xsl:text>

        <xsl:call-template name = "breadcrumb">
            <xsl:with-param name = "item" select =  
"$item/nav-item[descendant-or-self::nav-item[@location=$sourceLoc]]"/>
        </xsl:call-template>
    </xsl:if>
</xsl:template>
