Re: [xsl] copy attributes modifying their values, regardless of their names

[Emmanuel Bégué <eb@xxxxxxxxxx>]

Hi,

Wouldn't this work:

<xsl:template match="*">
	<xsl:copy>
		<xsl:for-each select="@*">
			<xsl:attribute name="{name()}">
				<xsl:call-template name="modify"/>
				</xsl:attribute>
			</xsl:for-each>
		<xsl:apply-templates/>
		</xsl:copy>
	</xsl:template>

...?
Regards,
EB
