Question

我有这样的XML - （简化）

<OrderBundle>
    <BundleDetail>
        <BundleId>12312</BundleId>
        <BundleUnit>
            <Idset>
                <PartNo>807651</PartNo>
            </Idset>
        </BundleUnit>
    </BundleDetail>
    <BundleDetail>
        <BundleId>12112</BundleId>
        <BundleUnit>
            <Idset>
                <PartNo>807650</PartNo>
            </Idset>
        </BundleUnit>
    </BundleDetail>
    <BundleDetail>
        <BundleId>12412</BundleId>
        <BundleUnit>
            <Idset>
                <PartNo>807651</PartNo>
            </Idset>
        </BundleUnit>
    </BundleDetail>
    <BundleDetail>
        <BundleId>12612</BundleId>
        <BundleUnit>
            <Idset>
                <PartNo>807651</PartNo>
            </Idset>
        </BundleUnit>
    </BundleDetail>
</OrderBundle>

我正在使用此XSL来查找循环中类似节点的先前值。我在这里简化了xsl，我需要在更大的集合中使用这个逻辑..

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">

<xsl:template match="/">

  <html>
  <body>

    <table border="1">
        <tr>
            <th>Bundle Id</th>
            <th>PartNo</th>
            <th>PreviousValue</th>
        </tr>
      <xsl:for-each select="/OrderBundle/BundleDetail">
      <tr>
        <td> <xsl:value-of select="BundleId"/></td>
        <td><xsl:value-of select=" BundleUnit/Idset/PartNo" /> </td>
        <td> ?? <xsl:value-of select="ancestor::BundleUnit/Idset/PartNo"/>   </td>
      </tr>
      </xsl:for-each>
    </table>


  </body>
  </html>
</xsl:template>

我尝试过祖先和前兄弟，对我不起作用.. 我期待以下结果

B.Id  PartNo PreviousValue 
12312 807651 ??             --
12112 807650 ??             -- 807651 
12412 807651 ??             -- 807650 etc
12612 807651 ??

请问任何想法？

使用：

preceding-sibling::BundleDetail[1]/BundleUnit/Idset/PartNo

完整转化：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format"> <xsl:template match="/"> <html> <body> <table border="1"> <tr> <th>Bundle Id</th> <th>PartNo</th> <th>PreviousValue</th> </tr> <xsl:for-each select="/OrderBundle/BundleDetail"> <tr> <td> <xsl:value-of select="BundleId"/></td> <td><xsl:value-of select=" BundleUnit/Idset/PartNo" /> </td> <td><xsl:value-of select="preceding-sibling::BundleDetail[1]/BundleUnit/Idset/PartNo"/> </td> </tr> </xsl:for-each> </table> </body> </html> </xsl:template> </xsl:stylesheet>

并生成了想要的正确结果：

<html xmlns:fo="http://www.w3.org/1999/XSL/Format"> <body> <table border="1"> <tr> <th>Bundle Id</th> <th>PartNo</th> <th>PreviousValue</th> </tr> <tr> <td>12312</td> <td>807651</td> <td></td> </tr> <tr> <td>12112</td> <td>807650</td> <td>807651</td> </tr> <tr> <td>12412</td> <td>807651</td> <td>807650</td> </tr> <tr> <td>12612</td> <td>807651</td> <td>807651</td> </tr> </table> </body> </html>

XSL - 循环中的上一个节点值
