RE: context-independent counter

Wow Ben,

it works!
(in instant saxon 6.0.2)

A context-independent counter in XSLT:

[in:]

<?xml version="1.0" encoding="UTF-8"?>
<list>
	<li>text</li>
	<li>text</li>
	<li>text</li>
	<li>text</li>
	<li>text</li>
	<li>text</li>
	<li>text</li>
	<li>text</li>
	<li>text</li>
	<li>text</li>
	<li>text</li>
	<li>text</li>
</list>

[through:]

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	<xsl:output method="xml" version="1.0"
encoding="UTF-8" indent="yes"/>
	<!--
	If you just want a counter, try something like this:
-->
	<xsl:template match="/">
		<svg>

		<xsl:call-template name="counter">
			<xsl:with-param name="i">1</xsl:with-param>
		</xsl:call-template>
		</svg>

	</xsl:template>
	<xsl:template name="counter">
		<xsl:param name="i"/>
		<!-- do something -->			<rect x="{$i * 10}" y="10"
width="6" height="4"/>		<xsl:if test="not($i > 10)">
			<xsl:call-template name="counter">
				<xsl:with-param name="i">
					<xsl:value-of select="$i +1"/>
				</xsl:with-param>
			</xsl:call-template>
		</xsl:if>
	</xsl:template>
	<!--
Basically, you are recursively calling a named
template with a 
parameter;
i.e. you can do a "for i = 1 to x" loop.

Hopefully this should be enough to get you going...-->
</xsl:stylesheet>

[out:]

<?xml version="1.0" encoding="UTF-8"?>
<svg>
	<rect x="10" y="10" width="6" height="4"/>
	<rect x="20" y="10" width="6" height="4"/>
	<rect x="30" y="10" width="6" height="4"/>
	<rect x="40" y="10" width="6" height="4"/>
	<rect x="50" y="10" width="6" height="4"/>
	<rect x="60" y="10" width="6" height="4"/>
	<rect x="70" y="10" width="6" height="4"/>
	<rect x="80" y="10" width="6" height="4"/>
	<rect x="90" y="10" width="6" height="4"/>
	<rect x="100" y="10" width="6" height="4"/>
	<rect x="110" y="10" width="6" height="4"/>
</svg>

again: wow!

Tobi
