您好我一直在尝试用连续数字替换某个标签中的值，我使用了位置功能，但它不起作用。 输入xml：

<?xml version="1.0" encoding="UTF-8"?>

            </DamagePosition>
         </Claim>
      </ClaimContext>
   </Content>
</Envelope>

在PartPosition / SeqNumber标签中的这个xml中，我想在SeqNumber标签中替换或生成数字序列。

我在xslt：

下面尝试过 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="utf-8" indent="no"/>
<xsl:key name="Damage_Group" match="/Envelope/Content/ClaimContext/Claim/DamagePosition" use="DamageCode" />
<xsl:template match="Claim">
<xsl:copy>
<xsl:apply-templates select="@*|node()" />
<xsl:for-each select="DamagePosition[count(. | key('Damage_Group', DamageCode)[1]) = 1]">
 <xsl:sort select="DamageCode" />
<DamagePosition>
<DamageSeqNumber>
<xsl:value-of select="position()" />
</DamageSeqNumber>
<DamageCode>
<xsl:value-of select="DamageCode" />
</DamageCode>
<WarrantyType><xsl:value-of select="WarrantyType" /></WarrantyType>
<xsl:for-each select="key('Damage_Group', DamageCode)">
<xsl:copy-of select="current()/PartPosition"/>
<xsl:copy-of select="current()/OperationPosition"/>
<xsl:copy-of select="current()/SubletPosition"/>
</xsl:for-each>
</DamagePosition>
</xsl:for-each>
</xsl:copy>
</xsl:template>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="DamagePosition">
</xsl:template>
</xsl:stylesheet>

但它没有给我如下所需的输出。

非常感谢任何帮助。

1 个答案:

答案 0 :(得分：0)

首先，不要这样做，而是复制元素而不对其进行进一步的更改（或其后代）

<xsl:copy-of select="current()/PartPosition"/>
<xsl:copy-of select="current()/OperationPosition"/>
<xsl:copy-of select="current()/SubletPosition"/>

您应该进行模板匹配，以便稍后编写模板以更改序列号

<xsl:apply-templates select="PartPosition"/>
<xsl:apply-templates select="OperationPosition"/>
<xsl:apply-templates select="SubletPosition"/>

现在，您可以做的是编写一个匹配各种Sequence数字的模板，并计算同一DamageCode的前一个兄弟姐妹。像这样的东西

<xsl:template match="PartPosition/SeqNumber">
  <SeqNumber>
    <xsl:variable name="DamageCode" select="../../DamageCode" />
    <xsl:value-of select="count(../../preceding-sibling::*[PartPosition][DamageCode = $DamageCode]) + 1" />
  </SeqNumber>
</xsl:template>

您也可以重复OperationPosition和SubletPosition的模板，尽管这会非常重复。或者，使用一个通用模板来匹配所有三个：

<xsl:template match="SeqNumber">
  <SeqNumber>
    <xsl:variable name="DamageCode" select="../../DamageCode" />
    <xsl:variable name="Parent" select="name(..)" />
    <xsl:value-of select="count(../../preceding-sibling::*[*[name() = $Parent]][DamageCode = $DamageCode]) + 1" />
  </SeqNumber>
</xsl:template>

然而，这并不一定有效，因为它没有使用密钥，因此必须通过所有前面的兄弟姐妹检查以找到匹配。

另一个解决方案是在参数中传递当前DamagePosition的位置，然后在检查密钥时使用它。

试试这个XSLT 

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
   <xsl:output method="xml" encoding="utf-8" indent="yes"/>
   <xsl:key name="Damage_Group"
            match="/Envelope/Content/ClaimContext/Claim/DamagePosition"
            use="DamageCode"/>

   <xsl:template match="Claim">
      <xsl:copy>
         <xsl:apply-templates select="@*|node()"/>
         <xsl:for-each select="DamagePosition[count(. | key('Damage_Group', DamageCode)[1]) = 1]">
            <xsl:sort select="DamageCode"/>
            <DamagePosition>
               <DamageSeqNumber>
                  <xsl:value-of select="position()"/>
               </DamageSeqNumber>
               <DamageCode>
                  <xsl:value-of select="DamageCode"/>
               </DamageCode>
               <WarrantyType>
                  <xsl:value-of select="WarrantyType"/>
               </WarrantyType>
               <xsl:for-each select="key('Damage_Group', DamageCode)">
                  <xsl:apply-templates select="PartPosition">
                      <xsl:with-param name="Position" select="position()" />
                  </xsl:apply-templates>
                  <xsl:apply-templates select="OperationPosition">
                      <xsl:with-param name="Position" select="position()" />
                  </xsl:apply-templates>
                  <xsl:apply-templates select="SubletPosition">
                      <xsl:with-param name="Position" select="position()" />
                  </xsl:apply-templates>
               </xsl:for-each>
            </DamagePosition>
         </xsl:for-each>
      </xsl:copy>
   </xsl:template>

    <xsl:template match="DamagePosition/*">
     <xsl:param name="Position" />
      <xsl:copy>
         <xsl:apply-templates select="@*|node()">
                <xsl:with-param name="Position" select="$Position" />
          </xsl:apply-templates>
      </xsl:copy>
   </xsl:template>

   <xsl:template match="SeqNumber">
      <xsl:param name="Position" />
      <SeqNumber>
        <xsl:value-of select="count(key('Damage_Group', ../../DamageCode)[position() &lt;= $Position][*[name() = name(current()/..)]])" />
      </SeqNumber>
   </xsl:template>

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

   <xsl:template match="DamagePosition" />
</xsl:stylesheet>
