Question

我是XSLT的新手，我在计算表中的子节总数时遇到问题。我正在使用XSLT 1.0。我能够从XML中获得Grand Total，但是获取子部分有很多ifs / else和条件很难解释。请在下面找到示例表和XML。

因此，我要做的是将文档1与文档2进行比较。如果Recno在两个文档中都匹配，则那些记录进入＆＃34;相同＆＃34;。如果Rec1在Document1中而不在Document2中，那么它将转到＆＃34; Add＆＃34;部分。如果Rec2在Document2中而不在Document1中，那么它将转到＆＃34;删除＆＃34;部分。

我到处尝试搜索但到目前为止没有运气。赞赏任何指针

我的输出HTML表格应如下所示：

----------------------------------------------------------------
Section         RecNo         Desc          Qty         Value   
----------------------------------------------------------------
Same             111        Desc1           1           $100.00
Same             444        Desc1           1           $200.00
Same             123        Desc1           1           $300.00
---------------------------------------------------------------
                          Same Total                    $600.00
---------------------------------------------------------------
Add             555         Desc1           1           $100.00
Add             999         Desc1           1           $100.00
---------------------------------------------------------------
                           Add Total                    $200.00
---------------------------------------------------------------
Delete          777         Desc1           1           $200.00
Delete          888         Desc1           1           $200.00
---------------------------------------------------------------
                           Delete Total                 $400.00
---------------------------------------------------------------
                         Grand Total                    $1200.00

这是我的XML

Answer 1

对于单个SO问题，我担心这可能有点太多了。我决定将您的输入简化为以下内容：

<Logia>
  <DocHeader>
        <Document>
            <Downto>
                <rec_no>111</rec_no>
                <desc>Desc1</desc>
                <qty>1</qty>
                <Value>100.00</Value>
            </Downto>
            <Downto>
                <rec_no>333</rec_no>
                <desc>Desc3</desc>
                <qty>3</qty>
                <Value>300.00</Value>
            </Downto>
            <Downto>
                <rec_no>444</rec_no>
                <desc>Desc4</desc>
                <qty>4</qty>
                <Value>400.00</Value>
            </Downto>
            <Downto>
                <rec_no>555</rec_no>
                <desc>Desc5</desc>
                <qty>5</qty>
                <Value>500.00</Value>
            </Downto>
        </Document>
        <Document>
            <Downto>
                <rec_no>222</rec_no>
                <desc>Desc2</desc>
                <qty>2</qty>
                <Value>200.00</Value>
            </Downto>
            <Downto>
                <rec_no>111</rec_no>
                <desc>Desc1</desc>
                <qty>1</qty>
                <Value>100.00</Value>
            </Downto>
            <Downto>
                <rec_no>444</rec_no>
                <desc>Desc4</desc>
                <qty>4</qty>
                <Value>400.00</Value>
            </Downto>
            <Downto>
                <rec_no>777</rec_no>
                <desc>Desc7</desc>
                <qty>7</qty>
                <Value>700.00</Value>
            </Downto>
            <Downto>
                <rec_no>888</rec_no>
                <desc>Desc8</desc>
                <qty>8</qty>
                <Value>800.00</Value>
            </Downto>
         </Document>
  </DocHeader>
</Logia>

请注意删除命名空间以及将 Value 值转换为数字。

应用以下样式表：

XSLT 1.0

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" omit-xml-declaration="yes" version="1.0" encoding="utf-8" indent="yes"/>
<xsl:strip-space elements="*"/>

<xsl:key name="doc1" match="Document[1]/Downto" use="rec_no" />
<xsl:key name="doc2" match="Document[2]/Downto" use="rec_no" />

<xsl:template match="/Logia/DocHeader">
    <table border="1">
        <!-- header -->
        <tr>
            <th>Section</th>
            <th>RecNo</th>
            <th>Desc</th>
            <th>Qty</th>
            <th>Value</th>
        </tr>
        <!-- same -->
        <xsl:variable name="same" select="Document[1]/Downto[key('doc2', rec_no )]" />  
        <xsl:apply-templates select="$same">
            <xsl:with-param name="section">Same</xsl:with-param>
        </xsl:apply-templates>
        <xsl:variable name="same-total" select="sum($same/Value)" />    
        <tr>
            <td colspan="4">Same Total</td>
            <th><xsl:value-of select="$same-total"/></th>
        </tr>
        <!-- add -->
        <xsl:variable name="add" select="Document[1]/Downto[not(key('doc2', rec_no ))]" />  
        <xsl:apply-templates select="$add">
            <xsl:with-param name="section">Add</xsl:with-param>
        </xsl:apply-templates>
        <xsl:variable name="add-total" select="sum($add/Value)" />  
        <tr>
            <td colspan="4">Add Total</td>
            <th><xsl:value-of select="$add-total"/></th>
        </tr>
        <!-- delete -->
        <xsl:variable name="delete" select="Document[2]/Downto[not(key('doc1', rec_no ))]" />   
        <xsl:apply-templates select="$delete">
            <xsl:with-param name="section">Delete</xsl:with-param>
        </xsl:apply-templates>

        <xsl:variable name="delete-total" select="sum($delete/Value)" />    
        <tr>
            <td colspan="4">Delete Total</td>
            <th><xsl:value-of select="$delete-total"/></th>
        </tr>
        <!-- grand total -->
        <tr>
            <th colspan="4">Grand Total</th>
            <th><xsl:value-of select="$same-total + $add-total + $delete-total"/></th>
        </tr>
    </table>
</xsl:template>

<xsl:template match="Downto">
    <xsl:param name="section"/>
    <tr>
        <td><xsl:value-of select="$section"/></td>
        <td><xsl:value-of select="rec_no"/></td>
        <td><xsl:value-of select="desc"/></td>
        <td><xsl:value-of select="qty"/></td>
        <td><xsl:value-of select="Value"/></td>
    </tr>
</xsl:template>

</xsl:stylesheet>

以上输入将导致：

<table border="1">
   <tr>
      <th>Section</th>
      <th>RecNo</th>
      <th>Desc</th>
      <th>Qty</th>
      <th>Value</th>
   </tr>
   <tr>
      <td>Same</td>
      <td>111</td>
      <td>Desc1</td>
      <td>1</td>
      <td>100.00</td>
   </tr>
   <tr>
      <td>Same</td>
      <td>444</td>
      <td>Desc4</td>
      <td>4</td>
      <td>400.00</td>
   </tr>
   <tr>
      <td colspan="4">Same Total</td>
      <th>500</th>
   </tr>
   <tr>
      <td>Add</td>
      <td>333</td>
      <td>Desc3</td>
      <td>3</td>
      <td>300.00</td>
   </tr>
   <tr>
      <td>Add</td>
      <td>555</td>
      <td>Desc5</td>
      <td>5</td>
      <td>500.00</td>
   </tr>
   <tr>
      <td colspan="4">Add Total</td>
      <th>800</th>
   </tr>
   <tr>
      <td>Delete</td>
      <td>222</td>
      <td>Desc2</td>
      <td>2</td>
      <td>200.00</td>
   </tr>
   <tr>
      <td>Delete</td>
      <td>777</td>
      <td>Desc7</td>
      <td>7</td>
      <td>700.00</td>
   </tr>
   <tr>
      <td>Delete</td>
      <td>888</td>
      <td>Desc8</td>
      <td>8</td>
      <td>800.00</td>
   </tr>
   <tr>
      <td colspan="4">Delete Total</td>
      <th>1700</th>
   </tr>
   <tr>
      <th colspan="4">Grand Total</th>
      <th>3000</th>
   </tr>
</table>

呈现为：
