Question

我是XSLT的新手，你能帮我解决我的xslt代码问题。我试图遍历每个xml记录，并根据每个Record xml条目的多个bu和主元数据生成li链接。我试图用HTML输出如下，文档和市场bu /主要行是超链接。

必需输出：

            Title 1 - Document BU and Primary sample links
              Document primary title one
              Document bu title one
              Document bu title two
              Document bu title three
              Document bu title four

            Title 2 - Market BU and Primary sample links
              Market primary title one
              Market bu title one
              Market bu title two
              Market bu title three
              Market bu title four

XSLT代码：

        <xsl:template match="R">
            <tr>
              <td>
                <xsl:choose>

                            <xsl:value-of select="count(meta[@name='primary' or @name='bu'])"/>

Answer 1

使用xslt时需要注意的一点是变量是不可变的。 XSLT是一种声明性的函数式编程语言，对于任何函数式语言，变量都是不可变的。

允许传入参数并且可以正常工作，但如果依靠该值来改变迭代，则在第一个模板中设置计数变量将不起作用。

下面的代码示例提供下面的输出，可以使用CSS格式化以满足您的需要。

Title 1 - Document BU and Primary sample links
    primary : asdwer12332334234123
    bu : werou2309weir23940293
    bu : xvxddc2309wei345weeffw
    bu : jljwerwoi798872334oweor
    bu : nnm23334hweiuroweir2
    S : ...Document Provide details. Share your research ...
    LANG : en

Title 2 - Market BU and Primary sample links
    primary : wwasdwer12332334234123
    bu : ddwerou2309weir23940293
    bu : ggxvxddc2309wei345weeffw
    bu : bbjljwerwoi798872334oweor
    bu : ssnnm23334hweiuroweir2
    S : ... Market Provide details. Share your research ...
