Re: FW: Recursion over a tree

Hello Geoff,

it's much easier you think. You only must process the nodes in document
order and for each ancestor a node has you must add a indent string:

<xsl:template match="*">
    <xsl:for-each select="ancestor::*">
        <xsl:text>    </xsl:text>
    </xsl:for-each>
    <xsl:value-of select="name()"/>
    <xsl:text>&#10;</xsl:text>
    <xsl:apply-templates select="*"/>
</xsl:template>

Or in HTML:

<xsl:template match="*">
    <div style="padding-left: 10px;">
        <xsl:value-of select="name()"/>
        <xsl:apply-templates select="*"/>
    </div>
</xsl:template>

Regards,

Joerg
