XSL problem

Image via Wikipedia

A while back I wrote some XSL to manipulate the SVG files my Groovy programs were outputting.

Now either I did something fancy back then that I have forgotten or else some piece of code has broken in the last couple of months (or maybe become less tolerant of my bad XML?) – because it doesn’t work now.

The XSL reads:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" indent="yes"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:param name="colour">yellow</xsl:param>
<xsl:template match="/">
	<xsl:apply-templates select="svg"/>
</xsl:template>
<xsl:template match="svg">
	<xsl:copy>
		<xsl:for-each select="@*">
			<xsl:copy/>
		</xsl:for-each>
		<xsl:text>
</xsl:text>
		<xsl:apply-templates select="rect"/>
		<xsl:apply-templates select="line"/>
		<xsl:apply-templates select="text"/>
		<xsl:apply-templates select="circle"/>
	</xsl:copy>
</xsl:template>
<xsl:template match="line">
	<xsl:copy>
		<xsl:for-each select="@*">
			<xsl:copy/>
		</xsl:for-each>
	</xsl:copy>
<xsl:text>
</xsl:text>
</xsl:template>
<xsl:template match="rect">
	<xsl:copy>
		<xsl:for-each select="@*">
			<xsl:copy/>
		</xsl:for-each>
	</xsl:copy>
<xsl:text>
</xsl:text>
</xsl:template>
<xsl:template match="text">
	<xsl:copy>
		<xsl:for-each select="@*|node()">
			<xsl:copy/>
		</xsl:for-each>
	</xsl:copy>
<xsl:text>
</xsl:text>
</xsl:template>
<xsl:template match="circle">
	<xsl:if test="@stroke=$colour">
		<xsl:copy>
			<xsl:for-each select="@*">
				<xsl:copy/>
			</xsl:for-each>
		</xsl:copy>
		<xsl:text>
</xsl:text>
	</xsl:if>
</xsl:template>
</xsl:stylesheet>

While the SVG (rather a small fraction of it) reads:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

But using xsltproc generates an empty output…
