如何过滤模板内数组中的项目？
How can I filter items in an array inside a template?
您好，我在 XSL 和过滤数组方面遇到了问题。
这是我的 XSL 转换：
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:ns0="http://xmlns.sse.com/SSEPD/GIS/PublishChangeSetEBM" xmlns:tns="http://xmlns.sse.com/SSEPD/GIS/UpdateLocationEBM" xmlns:oraxsl="http://www.oracle.com/XSL/Transform/java" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:plnk="http://docs.oasis-open.org/wsbpel/2.0/plnktype" xmlns:ns1="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:ns3="http://iec.ch/2002/schema/CIM_difference_model#" xmlns:ns4="http://xmlns.sse.com/SSEPD/GIS/ChangeSetEBO" xmlns:ns5="http://iec.ch/TC57/2010/CIM-schema-cim15#" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:ns2="http://xmlns.sse.com/Enterprise/Common" xmlns:client="http://xmlns.oracle.com/GIS_R1_SOA/SubstationEBS/SubstationEBS" xmlns:ns7="http://www.ibm.com/maximo" xmlns:ns6="http://xmlns.oracle.com/GIS_R1_SOA/UpdateLocationProviderABCS/UpdateLocationProviderABCS" xmlns:ns8="http://xmlns.sse.com/SSEPD/GIS/UpdateLocationEBO">

这是 XML 输入：

我遇到的问题是变量 $VOLTAGE_LEVEL。由于某种原因，我在模板函数中定义变量时应用的过滤条件不起作用。使用它的标签 ns7:VOLTAGE_LEVEL 在输出中为空。
我已经用不同的工具仔细检查过，并且做了不同的测试，看起来问题出在 $CURRENT_SUB 变量上。但这很奇怪，因为标签 ns7:LOCATION 正在显示正确的信息，并且它使用的变量 $LOCATION 是通过使用与 $VOLTAGE_LEVEL.
相同的方法填充的
你能看看吗？我一头雾水
注意：我使用的是样式表 2.0 版

您可以试试这个修改后的模板和谓词值：
<xsl:template match="/">
<tns:UpdateLocationEBM>

<xsl:apply-templates

</ns7:SSENLOCATIONSSet>
</ns7:SyncSSENLOCATIONS>
</tns:DataArea>
</tns:UpdateLocationEBM>
</xsl:template>
<xsl:template
