Hi all,
Just in case someone objects to the mixing of _stylesheet_ technologies,
here's a way to
wrap a long element set into a table (row/col) structure. [BTW: - like the
CSS flow, Rob.]
<xsl:variable name="num-cols" select="4"/>
<xsl:template match="fotografie">
<table>
<xsl:call-template name="layout-fotos">
<xsl:with-param name="fotos" select="foto"/>
</xsl:call-template>
</table>
</xsl:template>
<xsl:template name="layout-fotos">
<xsl:param name="fotos"/>
<tr>
<xsl:for-each select="fotos[position()<$num-cols">
<td><img src="[EMAIL PROTECTED]"/><br/><xsl:value-of select="."/></td>
</xsl:for-each>
</tr>
<xsl:if test="count(fotos)>$num-cols">
<xsl:call-template name="layout-fotos">
<xsl:with-param name="fotos" select="fotos[position()>$num-cols">
</xsl:call-template>
</xsl:if>
</xsl:template>
XSLT is declaritive and recursive - and it helps to be wired that way :)
Of course the other advantage (to Rob's future post) is that it's parsable
with any standard(s-compliant) XML parser - therefore includes some choice
and variety, as well as inheriting other properties of well-formedness, etc.
Extensions are getting better with EXSLT.

Hmmm... You seem to be making this much more complex than it needs to be.
Why not do something like this:
XSL:
<xsl:template match="fotografie">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="foto">
<div class="thumbnail" onclick="expandImage()">
<div class="imageContainer">
<img src="[EMAIL PROTECTED]" class="img"/>
</div>
<div class="description">
<xsl:apply-templates select="."/>
</div>
</div>
</xsl:template>
CSS:
.thumbnail {
display:inline;
margin:10px;
}
.imageContainer {
padding:3px;
border:1px solid blue;
}
.img {
width:20px;
height:20px;
}
description {
font-size:80%;
padding:10px;
}
With this you can have you gallery have the columns fit the width of the
(resized) window and they will wrap when necessary. Perhaps I am missing why
you need the complexity?
Best,
-Rob
