动态获取父节点及其值

问题描述 投票：0回答：2

我有一个 xml，可以在其中获取节点中节点的名称，例如值、宽度、高度、重量…… 示例：

我想要的是动态获取对应父节点的hte值。我可以获得如下节点名称：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="/">
    <table>
        <xsl:for-each select="/Data/ProductID/*">
            <xsl:variable name="myVariable" select="name(.)"/>
            <xsl:variable name="HasValue" select="count(/Data/ProductID/*)" />
            <tr>
                <td><xsl:value-of select="name(.)" /></td>
                <td><xsl:value-of select="local-name()" /></td>
                <td><xsl:value-of select="name()" /></td>
                <td><xsl:value-of select="/Data/node($myVariable)/@unit" /></td>
            </tr>
        </xsl:for-each>
    </table>
    </xsl:template>
</xsl:stylesheet>

但是我不知道如何获取相应的父节点及其值，例如单位元素。

我已经尝试过

<xsl:value-of select="/Data/$myVariable/@unit" /></td>
，但不起作用。我会不断收到错误：
Unexpected token '$myVariable' during parsing of '<AnyKindTest>'
。

我想你想声明一把钥匙

<xsl:key name="element-key" match="Data/Features" use="name()"/>

然后你想使用例如

key('element-key', name())/@unit
。

你写道：

<xsl:value-of select="/Data/$myVariable/@unit" />

我认为你的问题可能是重复的

使用 2 个参数进行 xslt 测试

您正在尝试使用 

$myVariable
，就好像它所保存的字符串可以以文本方式替换到您的 XPath 表达式中一样。您可能想要的是

/Data/*[name()=$myVariable]/@unit

很多人都犯过这个错误，但我不知道为什么。我不认为人们会将变量 

$op
设置为“+”或“-”，然后期望 
@x $op @y
执行适当的加法或减法。除非他们以前的编程经验完全是用宏语言。
