寻找一些想法 - 我有以下示例 XML 记录：

<?xml version="1.0"?>
<bdems:bulkDataRecord xmlns:bdems="http://www.imsglobal.org/services/lis/bdemsv1p0/imsbdemsFileData_v1p0">

      </bdems:parameterRecord>
    </bdems:parameterSet>
  </bdems:transactionRecord>
</bdems:bulkDataRecord>

我正在尝试使用以下 xsl 将其解析为对用户更友好的文件。

    <?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:bdems="http://www.imsglobal.org/services/lis/bdemsv1p0/imsbdemsFileData_v1p0" xmlns:cms="http://www.imsglobal.org/services/lis/cmsv1p0/imscms_v1p0">
  <xsl:template match="/">
    <combinations>
      <xsl:for-each select="//bdems:transactionRecord">
        <combination>
          <xsl:attribute name="id"> <xsl:value-of select="bdems:transactionOpIdentifier" /> </xsl:attribute>
          <id><xsl:value-of select="bdems:transactionOpIdentifier" /></id>
          <xsl:for-each select="bdems:parameterSet/bdems:parameterRecord">
            <xsl:if test="bdems:parameterName = 'sectionAssociationRecord'">
              <courses>
                <xsl:for-each select="bdems:parameterValue/cms:sectionAssociationRecord/cms:sectionAssociation">
                  <xsl:if test="cms:status = 'Active'">
                    <xsl:for-each select="cms:courseSectionIdList">
                      <course><xsl:value-of select="cms:courseSectionId" /></course>
                    </xsl:for-each>
                  </xsl:if>
                </xsl:for-each>
              </courses>
            </xsl:if>
          </xsl:for-each>
        </combination>
      </xsl:for-each>
    </combinations>
  </xsl:template>
</xsl:stylesheet>

一切正常，除了它只从 cms:courseSectionId 中提取第一条记录。

对为什么我只获得第一条记录有什么想法吗？

当前输出：

<?xml version="1.0"?>
<combinations xmlns:bdems="http://www.imsglobal.org/services/lis/bdemsv1p0/imsbdemsFileData_v1p0" xmlns:cms="http://www.imsglobal.org/services/lis/cmsv1p0/imscms_v1p0">
  <combination id="3064476-C-001355-01-2187-I0001">
    <id>3064476-C-001355-01-2187-I0001</id>
    <courses>
      <course>001355-01-2187-1-01-02642</course>
    </courses>
  </combination>
</combinations>

【解决方案1】：

你的最后一个在 courseSectionList 上。只有一个列表，有多个 courseSectionId。如果您将 for-each 选择更改为 courseSectionId，它将起作用。

我测试了更改，生成了以下 XSLT

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:bdems="http://www.imsglobal.org/services/lis/bdemsv1p0/imsbdemsFileData_v1p0" xmlns:cms="http://www.imsglobal.org/services/lis/cmsv1p0/imscms_v1p0">
  <xsl:template match="/">
    <combinations>
      <xsl:for-each select="//bdems:transactionRecord">
        <combination>
          <xsl:attribute name="id"> <xsl:value-of select="bdems:transactionOpIdentifier" /> </xsl:attribute>
          <id><xsl:value-of select="bdems:transactionOpIdentifier" /></id>
          <xsl:for-each select="bdems:parameterSet/bdems:parameterRecord">
            <xsl:if test="bdems:parameterName = 'sectionAssociationRecord'">
              <courses>
                <xsl:for-each select="bdems:parameterValue/cms:sectionAssociationRecord/cms:sectionAssociation">
                  <xsl:if test="cms:status = 'Active'">
                    <xsl:for-each select="cms:courseSectionIdList/cms:courseSectionId">
                      <course><xsl:value-of select="." /></course>
                    </xsl:for-each>
                  </xsl:if>
                </xsl:for-each>
              </courses>
            </xsl:if>
          </xsl:for-each>
        </combination>
      </xsl:for-each>
    </combinations>
  </xsl:template>
</xsl:stylesheet>
