我有以下XML：

</STEP-ProductInformation>

和规则如果属性'atr_ext_var_list_max_until'中的日期＆lt; =当前日期比：

  • 'atr_storage_num'必须为空

  • 'atr_shelf_num'必须为空

  • 'atr_renewable_goods_quantity'设为0

我的XSL转换（没有规则'atr_ext_var_list_max_until'＆lt; =当前日期）：

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:java="http://xml.apache.org/xslt/java" exclude-result-prefixes="java" version="1.0">

    <xsl:output method="xml" indent="yes"/>

    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>


    <xsl:variable name="currdate" select="java:format(java:java.text.SimpleDateFormat.new('yyyy-MM-dd'), java:java.util.Date.new())" /> 
    <xsl:variable name="date" select="/STEP-ProductInformation/Products/Product/Values/Value[@AttributeID = 'atr_ext_var_list_max_until']" />
    <xsl:variable name="bool" select="$date = $currdate" /> 


    <xsl:template match="node()[@AttributeID = 'atr_storage_num']">
            <xsl:variable name="vAttribs" select="@AttributeID | @Derived"/>
            <xsl:variable name="date" select="/STEP-ProductInformation/Products/Product/Values/Value[@AttributeID = 'atr_ext_var_list_max_until']" />
            <Value><xsl:copy-of select="$vAttribs"/><xsl:text>CONST1</xsl:text><xsl:comment><xsl:value-of select="$date" /></xsl:comment></Value>
    </xsl:template>


    <xsl:template match="node()[@AttributeID = 'atr_shelf_num']">       
            <xsl:variable name="vAttribs" select="@AttributeID | @Derived"/>
            <Value><xsl:copy-of select="$vAttribs"/><xsl:text>CONST2</xsl:text></Value>     
    </xsl:template>

    <xsl:template match="node()[@AttributeID = 'atr_renewable_goods_quantity']">
            <xsl:variable name="vAttribs" select="@AttributeID | @Derived"/>
            <Value><xsl:copy-of select="$vAttribs"/><xsl:text>CONST3</xsl:text></Value>         
    </xsl:template> 

</xsl:stylesheet>

<!-- <xsl:comment><xsl:value-of select="$bool" /></xsl:comment> -->

不起作用。 使用这个XSL后我得到：

 <?xml version="1.0" encoding="UTF-8"?>
<STEP-ProductInformation ExportTime="2016-08-08 18:21:16" ExportContext="en-EN" ContextID="en-EN" WorkspaceID="Main" UseContextLocale="false">

    </Classifications>
       <Products>
          <Product ID="prd_119481004" UserTypeID="obj_product" ParentID="prd_eng_10000807">
             <Name>product name1</Name>
            ...
                <Value AttributeID="atr_renewable_goods_quantity">CONST3</Value>
                <Value AttributeID="atr_ext_var_list_max_until">2017-09-08</Value>              
                <Value AttributeID="atr_shelf_num" Derived="true">CONST2</Value>
                <Value AttributeID="atr_storage_num" Derived="false">CONST1<!--2017-09-08--></Value>
            ...
             </Values>
          </Product>
          <Product ID="prd_119478004" UserTypeID="obj_product" ParentID="prd_eng_10000807">
             <Name>product name2</Name>             
            ...
                <Value AttributeID="atr_ext_var_list_max_until">2015-12-31</Value>             
                <Value AttributeID="atr_shelf_num" Derived="true">CONST2</Value>
                <Value AttributeID="atr_storage_num" Derived="true">CONST1<!--2017-09-08--></Value>
            ...
             </Values>
          </Product>
       </Products>
    </STEP-ProductInformation>

对于调试，我使用<comment>并在结果的第二个上下文中获取来自源的第一个上下文的值。 谁知道我必须如何改变我的XSL转换以获得正确的上下文值： 在源<Value AttributeID="atr_ext_var_list_max_until">2017-09-08</Value>的第一个到结果<Value AttributeID="atr_storage_num" Derived="false">CONST1<!--2017-09-08--></Value>和<Value AttributeID="atr_ext_var_list_max_until">2015-12-31</Value>到<Value AttributeID="atr_storage_num" Derived="true">CONST1<!--2015-12-31--></Value>的第一个，而不是第一个上下文的值2017-09-08 ？ 谢谢！

答案 0 :(得分：0)

假设我正确理解您的问题而您只关心CONST1日期，则需要更改

<xsl:variable name="date" select="/STEP-ProductInformation/Products/Product/Values/Value[@AttributeID = 'atr_ext_var_list_max_until']" />

到

<xsl:variable name="date" select="../Value[@AttributeID = 'atr_ext_var_list_max_until']" />

您当前的XSL将从根目录中查找与该路径匹配的节点。 “..”表示从您正在查看的当前节点的父节点开始搜索。
