RE: any ideas?

[Ben Robb <Ben@xxxxxxxxxx>]

You could use a code like this (NB. Not tested, or even checked for
well-formed XML/XSL *grin*):

+++ XML +++

<SITE>
	<SECTION ID="1" LEVEL="1" TITLE="Section 1" LINK=""/>
	<SECTION ID="2" LEVEL="1" TITLE="Section 2" LINK="">
		<SECTION ID="3" LEVEL="2" TITLE="Section 2.1" LINK=""/>
		<SECTION ID="4" LEVEL="2" TITLE="Section 2.2" LINK=""/>
	</SECTION>
...
</SITE>

+++ XSL +++

<xsl:for-each select="//SITE/SECTION">
	<div onclick="JavaScript:displayChild()">
		<xsl:attribute name="id">parent<xsl:value-of
select="@ID"/></xsl:attribute>
		<img src="plus.gif"/><xsl:value-of select="@TITLE"/>
	</div>
	<div style="display:none">
		<xsl:attribute name="id">child<xsl:value-of
select="@ID"/></xsl:attribute>
		
		<xsl:for-each select="SECTION">
			<xsl:value-of select="@TITLE"/><BR/>
		</xsl:for each>
	</div>
</xsl:for-each>

The JavaScript function "displayChild()" basically sets the style of display
for the second div tag to be "" (ie. makes the child visible). I've left it
to you to add things like positioning to get the div tags to appear in the
right place.

There are a couple of problems with this method

1) This will only work if there are two levels. Does anyone know of a way to
do recursive for loops? Like "Carry on going down the tree doing the same
sort of thing as long as there are more SECTION elements beneath it" without
hard coding? I'm sure there is a way...

2) I toyed with the idea of making it a flat structure, which would mean
that the order becomes very important, but gets rid of the problem in (1).
ie:

<SITE>
	<SECTION ID="1" LEVEL="1" TITLE="Section 1" LINK=""/>
	<SECTION ID="2" LEVEL="1" TITLE="Section 2" LINK=""/>
	<SECTION ID="3" LEVEL="2" TITLE="Section 2.1" LINK=""/>
	<SECTION ID="4" LEVEL="2" TITLE="Section 2.2" LINK=""/>
	
...
</SITE>


The problem with that, though, is that it is difficult to target the correct
div tags to show and hide on the fly (since you don't know the "parent" of
the item in the index.

Anyone else have any thoughts?
