XSLT:根据子值显示元素和子元素

问题描述 投票:0回答:1

我的 XML 代码显示员工的所有地址及其使用类型。仅当地址具有特定使用类型时才必须显示。其他的必须删除。

下面是xml。

<peci:Person_Communication>
    <peci:Address>
        <peci:Usage_Type>HOME1</peci:Usage_Type>
        <peci:Address_Line_1>Gen. Sochora</peci:Address_Line_1>
        <peci:Address_Line_3>31</peci:Address_Line_3>
        <peci:Address_Line_4>957</peci:Address_Line_4>
        <peci:City>Třebíč</peci:City>
        <peci:Postal_Code>674 01</peci:Postal_Code>
        <peci:Country>CZ</peci:Country>
        <peci:Usage>
            <peci:Usage_Behavior_ID>COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-6</peci:Usage_Behavior_ID>
        </peci:Usage>

    <peci:Address>
        <peci:Usage_Type>HOME2</peci:Usage_Type>

        <peci:Usage>
            <peci:Usage_Behavior_ID>COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-8</peci:Usage_Behavior_ID>
        </peci:Usage>
        <peci:Usage>
            <peci:Usage_Behavior_ID>COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-9</peci:Usage_Behavior_ID>

        <peci:Postal_Code>674 01</peci:Postal_Code>
        <peci:Country>CZ</peci:Country>
        <peci:Usage>
            <peci:Usage_Behavior_ID>COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-1</peci:Usage_Behavior_ID>
        </peci:Usage>
        <peci:Usage>

        <peci:Postal_Code>674 01</peci:Postal_Code>
        <peci:Country>CZ</peci:Country>
        <peci:Usage>
            <peci:Usage_Behavior_ID>COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-10</peci:Usage_Behavior_ID>
        </peci:Usage>
        <peci:Usage>
            <peci:Usage_Behavior_ID>COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-8</peci:Usage_Behavior_ID>
        </peci:Usage>
        <peci:Usage>
            <peci:Usage_Behavior_ID>COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-6</peci:Usage_Behavior_ID>
        </peci:Usage>
        <peci:Usage>
            <peci:Usage_Behavior_ID>COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-1</peci:Usage_Behavior_ID>
        </peci:Usage>
    </peci:Address>
</peci:Person_Communication>
必须显示仅包含

COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-1

COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-16
COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-6
地址以及不包含Usage 元素的地址。其余部分已被删除。

下面是我在 XSLT 代码中编写的逻辑。

<xsl:template match="peci:Person_Communication/peci:Address">
    <xsl:variable name="AddUsage1" select="peci:Usage/peci:Usage_Behavior_ID[.='COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-16' or .='COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-6' or .='COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-1']"/>
    <xsl:variable name="AddUsage2" select="peci:Usage/peci:Usage_Behavior_ID[.='COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-9' or .='COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-8' or .='COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-10' or .='COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-11' or .='COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-12' or .='COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-13']"/>
    <xsl:choose>
        <xsl:when test="$AddUsage1 and not($AddUsage2)">
            <xsl:copy-of select="."/>
        </xsl:when>
        <xsl:when test="$AddUsage1 and $AddUsage2">
            <xsl:copy-of select="peci:Usage_Type|peci:Address_Line_1|peci:Address_Line_3|peci:Address_Line_4|peci:City|peci:Postal_Code|peci:Country|peci:Country_Region"/>
            <peci:Usage>
                <xsl:copy-of select="$AddUsage1"/>
            </peci:Usage>
        </xsl:when>
        <xsl:when test="not($AddUsage1) and not($AddUsage2)">
            <xsl:copy-of select="."/>
        </xsl:when>
    </xsl:choose>
</xsl:template>`

下面是输出。

<peci:Person_Communication>
    <peci:Address>
        <peci:Usage_Type>HOME1</peci:Usage_Type>
        <peci:Address_Line_1>Gen. Sochora</peci:Address_Line_1>

                            <peci:Usage_Behavior_ID>COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-1</peci:Usage_Behavior_ID>
                        </peci:Usage>
                    </peci:Person_Communication>

对于变量 $AddUsage1 和 $AddUsage2 都存在的情况,元素 peci:Address/ 丢失,并且使用行为的所有值都放置在单个 peci:Usage 下,而不是单独的元素下。请帮我修复以下逻辑。

<xsl:when test="$AddUsage1 and $AddUsage2">
    <xsl:copy-of select="peci:Usage_Type|peci:Address_Line_1|peci:Address_Line_3|peci:Address_Line_4|peci:City|peci:Postal_Code|peci:Country|peci:Country_Region"/>
    <peci:Usage>
        <xsl:copy-of select="$AddUsage1"/>
    </peci:Usage>
</xsl:when>

首先,让我提醒您,获得及时回复的最佳方法是在提问时注意您已提供所有相关信息。

您需要包括:

  • 输入数据(您的数据无效,因为它省略了
    peci
    命名空间前缀的声明;在我的示例中,我已将
    peci
    绑定到占位符值
    not-supplied
  • 您现有的完整运行代码(您的不是完整的样式表)

参见 https://stackoverflow.com/help/minimal-reproducible-example

如果我理解正确的话,这是您问题的答案。

我知道您想要删除任何

peci:Address
,如果它包含一个
peci:Usage/peci:Usage_Behavior_ID
,其值不是这三个可接受值之一:

  • COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-1
  • COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-16
  • COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-6

我的示例解决方案使用“身份模板”来复制文档,并定义另一个模板来匹配不可接受的

peci:Address
元素,该模板会覆盖这些元素的身份模板。
peci:Address
匹配模板为空,因此匹配的结果是忽略该元素,因此不会将其复制到输出中。

请参阅 XSLT 2.0 规范中有关“身份转换”的部分,其中给出了复制文档并忽略特定

note
元素的示例。 https://www.w3.org/TR/xslt20/#d5e17568

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:peci="not-supplied">
  
  <xsl:output method="xml" indent="true"/>

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

<!--
Match, and ignore, any Address which contains
   a Usage/Usage_Behaviour_ID for which
      it's not the case that the ID appears in the list of acceptable IDs
-->

  <xsl:template match="
    peci:Address[
      peci:Usage/peci:Usage_Behavior_ID[
        not ( . = 
          (
            'COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-1',
            'COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-16',
            'COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-6'
          )
        )
      ]
    ]
  "/>

</xsl:stylesheet>

顺便说一句,如果您想知道,布尔表达式

        not ( . = 
          (
            'COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-1',
            'COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-16',
            'COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-6'
          )
        )

不等于

        . != (
            'COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-1',
            'COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-16',
            'COMMUNICATION_USAGE_BEHAVIOR_TENANTED-3-6'
          )

在第一个表达式中,如果序列中的

any
项等于上下文项,则
=
运算符返回 true

在第二个表达式中,如果序列中的

any
项与上下文项不同,则
!=
运算符返回 true

一般来说,

not($A = $B)
$A != $B
不同。有关详细信息,请参阅 XPath 规范中有关 “常规比较” 的部分。
