Re: empty attribute tags rendering in HTML

Hi Bonnie,

Try this out:

<?xml version='1.0'?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">
	<xsl:apply-templates/>
</xsl:template>

<xsl:template match="a|td|img">
	<xsl:element name="{name()}">
	<xsl:for-each select="@*">
		<xsl:if test="not(normalize-space(.) = '')">
			<xsl:attribute name="{name()}"><xsl:value-of select="."/></xsl:attribute>
		</xsl:if>
	</xsl:for-each>
	<xsl:apply-templates/>
	</xsl:element>
</xsl:template>

</xsl:stylesheet>
