XSLT:处理忽略大小写和循环

Question

我有一个问题，而忽略大小写获取值。发生的情况是，当用户输入他们使用的设备数据时，他们可能会输入38e135作为设备编号，但稍后在表单中他们可能会输入38e135。当我循环遍历设备id时，我需要将它们视为一个。

当我尝试这样做时，我得到它们作为两个不同的设备编号。

<xsl:key name="distinctEquipNum" match="//EquipmentNumber" use="."/>

当我尝试使用翻译函数时，我只得到其中一个。

<xsl:key name="distinctEquipNum" match="//EquipmentNumber" use="translate(., 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz')"/>

这是我用来获取数据

的循环

<xsl:for-each select=".//EquipmentNumber[generate-id() = generate-id(key('distinctEquipNum', .)[1])]">
        <xsl:variable name="equipNum" select="."></xsl:variable>
        <td><xsl:value-of select="$equipNum"/></td>

是否有一种方法可以让我循环遍历设备编号并忽略大小写?

这是我正在使用的XML示例，

<Timesheet>
    <Equipment>
      <EquipmentWorkOrder>
         <EquipmentWorkOrderNumber>220923134</EquipmentWorkOrderNumber>

Answer 1

您需要对用于从键检索的值应用与定义时使用的相同的转换，即，如果键是

<xsl:key name="distinctEquipNum" match="EquipmentNumber"
 use="translate(., 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz')"/>

则Muenchian分组表达式需要做相同的translate

<xsl:for-each select=".//EquipmentNumber[generate-id() =
    generate-id(key('distinctEquipNum',
      translate(., 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz')
    )[1])]">

(注意在键的match表达式中不需要//，只需使用match="EquipmentNumber")
