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> I am seeking to create a similar control to the one seen here: http://www.15seconds.com/issue/010921.htm 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. Here is the beginning of my stylesheet. <?xml version="1.0" encoding="iso-8859-1"?> <xsl:stylesheet version="1.1" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:param name="css"/> <xsl:param name="c_node"/> <xsl:param name="url"/> <xsl:output method="html" indent="yes"/> <xsl:template match="tree"> <table class="{$css}" align="center"> <xsl:apply-templates /> </table> </xsl:template> <xsl:template match="//tree_node"> <tr> <td width="{(@depth + 1) * 20}" align="right"> <a href="{$url}&node={@id}">+</a> </td> <td> <xsl:value-of select="@value"/> </td> </tr> <xsl:apply-templates select="*[descendant-or-self::*/@id=$c_node]"/> </xsl:template> </xsl:stylesheet> I am only acquainted with xsl, so I would sure appreciate any suggestions on how to do this. I cant get past displaying the level (depth) 0 nodes, even when I click the appropriate link. Cheers, Adam
