xml – XSLT：属性中的’xsl：value-of’

<xsl:for-each select="refsect1[@id = 'seealso']/para/citerefentry">
  /// <seealso cref=""/>
  <xsl:value-of select="refentrytitle" />
</xsl:for-each>

如何将refentrytitle的值放在模板中seealso标记的cref属性中？

I don’t understand how place the value of refentrytitle in the cref
attribute of the seealso tag in the template.

只需将表达式放在大括号内(这称为Attribute Value Templates或简称为AVT语法),如下所示：

<seealso cref="{refentrytitle}"/>
