Question

我遇到了一些问题XML，我正在尝试从中创建可用的XML，但我的XSLT无法正常工作。我有顶部工作，但我无法将数据显示在下半部分。

以下是XML数据的示例：

<crystalreports>

这是XSLT：

<?xml version="1.0"?><!-- DWXMLSource="STX049 Course Catalog Parsed.xml" -->
<!DOCTYPE xsl:stylesheet>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="no"/>

<xsl:key name="degrees-by-title" match="Group/Group/Group/Details" use="Section/DEPTSDESC1" />

<xsl:template match="CrystalReport">

<crystalreports>
<xsl:for-each select="Group/Group/Group/Details[count(. | key('degrees-by-title', Section/DEPTSDESC1)[1]) = 1]">
<department>
<Degreetitle><xsl:value-of select="Section/ACPGDEGREE1"/></Degreetitle><xsl:text> DEGREE 
</xsl:text><DegreeDesc><xsl:value-of select="Section/ACPGCOMMENTS1"/></DegreeDesc><xsl:text> 
ICCB Code </xsl:text><ICCBcode><xsl:value-of select="Section/ICCB1"/></ICCBcode><xsl:text> | Field of Study     Code: </xsl:text><ProgramID><xsl:value-of select="Section/ACADPROGRAMSID1"/></ProgramID><xsl:text> 
Program Requirements
</xsl:text>
<xsl:for-each select="key('degrees-by-title', Section/DEPTSDESC1)">
<xsl:sort select="Section/DEPARTMENT12" />
<Details> 
<class><deptname><xsl:value-of select="Section/DEPARTMENT12"/></deptname><xsl:text> </xsl:text><courseno>    <xsl:value-of select="Section/CRSNO1"/></courseno><classname><xsl:value-of select="Section/CRSTITLE11"/>    </classname><xsl:text> </xsl:text><classcredit><xsl:value-of select="Section/CRSMINCRED1"/></classcredit>    </class><xsl:text>
</xsl:text> 
</Details>
</xsl:for-each>
</department><xsl:text>
</xsl:text>
</xsl:for-each>
</crystalreports>
</xsl:template>
</xsl:stylesheet>

上半部分正常工作，但我没有在底部循环中获取任何数据，也无法找出原因。

基本上，我想这样结束：

<crystalreports>
<department>
<Degreetitle>ACPGDEGREE1</Degreetitle> DEGREE 
<DegreeDesc>ACPGCOMMENTS1</DegreeDesc>
ICCB Code <ICCBcode>ICCB1</ICCBcode> | Field of Study  Code: <ProgramID>ACADPROGRAMSID1</ProgramID>

Program Requirements
<xsl:for-each select="key('degrees-by-title', Section/DEPTSDESC1)">
<xsl:sort select="Section/DEPARTMENT12" />
<Details> 
<class><deptname>DEPARTMENT12</deptname><courseno>CRSNO1</courseno><classname>CRSTITLE11</classname <classcredit>CRSMINCRED1</classcredit></class>
</Details>
</xsl:for-each>
</department>
</xsl:for-each>
</crystalreports>

Answer 1

假设XML样本中的多个根是OP的错误，那么解决方案就在下面。

这是错误的：

xsl:template match="CrystalReport"需要替换为匹配的XML元素路径（源XML中没有CrystalReport标记;
degrees-by-title密钥使用了不存在的节点名称。

使用XSLT对数据进行分组缺少结果
