XML Tutorial/XSLT stylesheet/attribute set
Several attributes can be grouped together and then used at once with xsl:attribute-set and xsl:use-attribute-sets
File: Data.xml
<?xml version="1.0" encoding="utf-8"?>
<data>
<TITLE>GREETING</TITLE>
<TEXT>Hello, world!</TEXT>
</data>
File: Transform.xslt
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match=" TITLE">
<H1 xsl:use-attribute-sets="titleStyle">
<xsl:value-of select="."/>
</H1>
</xsl:template>
<xsl:template match=" TEXT">
<P xsl:use-attribute-sets="textStyle">
<xsl:value-of select="."/>
</P>
</xsl:template>
<xsl:attribute-set name="titleStyle">
<xsl:attribute name="align">center</xsl:attribute>
<xsl:attribute name="style">color:red</xsl:attribute>
</xsl:attribute-set>
<xsl:attribute-set name="textStyle">
<xsl:attribute name="align">right</xsl:attribute>
<xsl:attribute name="style">color:blue</xsl:attribute>
</xsl:attribute-set>
</xsl:stylesheet>
Output:
<?xml version="1.0" encoding="UTF-8"?>
<H1 align="center" style="color:red">GREETING</H1>
<P align="right" style="color:blue">Hello, world!</P>
