RE: for-each sort of thing in {} ?

[Ben Robb <Ben@xxxxxxxxxx>]

If you put it in a variable, you should be able to do it... try:

<xsl:template match="foo">

<xsl:variable name="qstring">
	<xsl:for-each select="bar">
		<xsl:if test="postition() != 1">
			&amp;
		</xsl:if>
		id<xsl:value-of select="position()"/>=<xsl:value-of
select="@id"/>
	</xsl:for-each>
</xsl:variable>

<a href="foo.php3?{$qstring}">Link here!</a>

</xsl:template>

Not tested for well-formedness etc, but it should work.
