Hi all,
First time posting, so I hope I am doing ok.
I have a xml document that gets generated from a database (MySql). <?xml version="1.0"?> <tree> <tree_node id="7" depth="0" parent="0" value="Test"> <tree_node id="8" depth="1" parent="7" value="Test Sub"/> <tree_node id="9" depth="1" parent="7" value="Test Sub One"> <tree_node id="10" depth="2" parent="9" value="Test Sub Two"/> </tree_node> </tree_node> </tree>
However all xsl processing is done server side (Using PHP 4 XSLT Processor). Default view is all level (depth) 0 nodes displayed. A user clicks a html link that sends the id of the node clicked to the xsl file as a parameter and all children nodes are displayed. If depth is greater than one, all ancestor nodes will need to be displayed also.
<xsl:template match="/"> <ul class="nav"> <xsl:apply-templates/> </ul> </xsl:template>
<xsl:template match="*"> <xsl:choose> <xsl:when test="child::*"> <li class="folder"> <a href="my.php?id={@id}"> <xsl:value-of select="@value"/> </a> <ul> <xsl:apply-templates/> </ul> </li> </xsl:when> <xsl:otherwise> <li class="page"> <a href="my.php?id={@id}"> <xsl:value-of select="@value"/> </a> </li> </xsl:otherwise> </xsl:choose> </xsl:template>
best, -Rob
