XSLT for-每个循环表输出

Question

我想用XSLT创建一个表，其中流程阶段是头，processNo是值。

  <PV_Batch masterBatchNo="KH8944">
    <tempTable processStage="Blending" processNo="KF0285" />
    <tempTable processStage="Coating" processNo="KF0282" />
    <tempTable processStage="Compression" processNo="KF0283" />
    <tempTable processStage="Granulation" processNo="12345" />
    <tempTable processStage="Granulation" processhNo="KF0284" />
    <tempTable processStage="Mixing" processNo="KF0286" />
    <tempTable processStage="mixing" processNo="K12035" />
  </PV_Batch>

Blending | Coating | Compression | Granulation | Mixing
KF0285   | KF0282  | KF0283      | 12345       | KF0286
         |         |             | Kf0284      | K12035

我有问题重复的价值观，每当我有重复，他们只是越界，像这样。

Blending | Coating | Compression | Granulation | Mixing
KF0285   | KF0282  | KF0283      | 12345       | Kf0284  | KF0268  | K12035

下面是我的表xslt样式表中的代码片段。

          <xsl:for-each select="//tempTable[generate-id() = generate-id(key('keyComponent', @processStage)[1])]">

              <th width="" align="Left" class="tableHeaderRow">
                  <xsl:value-of select="@processStage" />
                </th>

          </xsl:for-each>

          <tr>
            <xsl:for-each select="tempTable">
              <td align="Left" class="tableNormalRow">
                <xsl:value-of select="@processNo"/>
              </td>
            </xsl:for-each>
          </tr>

Answer 1

所显示的代码段中的第二个循环必须执行与头循环相同的分组：

<xsl:for-each select="//tempTable[generate-id() = generate-id(key('keyComponent', @processStage)[1])]">
      <!-- get current processStage -->
      <xsl:variable name="processStage" select="@processStage"/>
      <td align="Left" class="tableNormalRow">
      <!-- loop over all tempTable belonging to current processStage -->
      <xsl:for-each select="//tempTable[@processStage=$processStage]">
          <p>                  
              <xsl:value-of select="@processNo"/>
          </p>
      </xsl:for-each>
      </td>
</xsl:for-each>

如果一个processStage有多个值，这将把每个值放在同一个td中的p中，所以这个表：

Blending | Coating | Compression | Granulation | Mixing
KF0285   | KF0282  | KF0283      | 12345       | KF0286
         |         |             | Kf0284      | K12035

将仅由2行组成。

但是，如果这应该生成一个3行的表，那么解决方案就会稍微复杂一些。

XSLT2.0解决方案：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">

<xsl:output indent="yes"/>

<xsl:variable name="processStages" select="distinct-values(//tempTable/@processStage)"/>

<xsl:variable name="maxRows"
    select="max(for $i in $processStages return count(//tempTable[@processStage=$i]))"/>

<xsl:template match="PV_Batch">
    <table>
        <tr>
            <xsl:for-each-group select="tempTable" group-by="@processStage">
                <th width="" align="Left" class="tableHeaderRow">
                    <xsl:value-of select="@processStage"/>
                </th>
            </xsl:for-each-group>
        </tr>

        <xsl:variable name="tempTable" select="tempTable"/>
        <xsl:for-each select="1 to $maxRows">

            <tr>

                        <xsl:value-of select="$tempTable[@processStage=current()][$pos]/@processNo"/>
                    </td>
