W3CHINA.ORG讨论区--xslt 不能进行减法运算，着急

贴子主题： xslt 不能进行减法运算，着急

本主题类别: 样式表技术(XSL, XSLT, XSL-FO, CSS)

我写了一个xslt，但是在里面不能进行减法运算，我贴一段代码和错误信息，麻烦帮我看看，谢谢！

    <xsl:param name="all" select="10"/>
    <xsl:param name="part" select="1"/>
    x=<xsl:value-of select="($all-$part)"/>

- 就是减号的转义

错误：““($all-$part)”中的语法错误。”
致命错误：“无法编译样式表”
