xsl:copy 元素可以带一个 use-attribute-sets 属性。这样就可以同时复制节点的属性集。 XSLT stylesheet 2 并不像想象的那样工作( 在 name 函数中使用了 use-attribute-sets)。这是因为属性中的表达式还没有被求值。

XSLT stylesheet 1

XML源码

<source>

<h1>GREETING</h1>
<p>Hello, world!</p>

</source>

输出

<h1 align="center" style="color:red">GREETING</h1>
<p align="left" style="color:blue">Hello, world!</p>

用HTML察看

GREETING

Hello, world!

XSLT stylesheet

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

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

<xsl:template match="h1">
     <xsl:copy use-attribute-sets="H1">
          <xsl:value-of select="."/>
     </xsl:copy>
</xsl:template>

<xsl:template match="p">
     <xsl:copy use-attribute-sets="P ">
          <xsl:value-of select="."/>
     </xsl:copy>
</xsl:template>

<xsl:attribute-set name="H1">
     <xsl:attribute name="align">center</xsl:attribute>
     <xsl:attribute name="style">color:red</xsl:attribute>
</xsl:attribute-set>
<xsl:attribute-set name="P">
