如何解决为嵌套XML生成XSL非规范化格式
由于文件大小非常大且处于嵌套级别,因此我需要弄平XML,我正在手动创建XSL文件。下面是我的XML文件内容示例场景-
<StudentDetail>
<SchoolName>SSHPS</SchoolName>
<SchoolEstablishedYear>1990</SchoolEstablishedYear>
<ClassDetails>
<ClassDetail>
<ClassStartedYear>1990</ClassStartedYear>
<Section ID="12345">
<SectioName>Section A</SectioName>
<Students>
<Student ID="1">
<StudentName>John</StudentName>
<Address>
<HomeNumber>10</HomeNumber>
<StreetName>Avenue</StreetName>
</Address>
</Student>
<Student ID="2">
<StudentName>Steve</StudentName>
</Student>
</Students>
</Section>
<Section ID="123456">
<SectioName>Section B</SectioName>
<Students>
<Student ID="100">
<StudentName>Dia</StudentName>
<Age>6</Age>
</Student>
<Student ID="101">
<StudentName>Kevin</StudentName>
</Student>
</Students>
</Section>
</ClassDetail>
<ClassDetail>
<ClassStartedYear>1995</ClassStartedYear>
<Section ID="543466">
<SectioName>Section A</SectioName>
<Students>
<Student ID="200">
<StudentName>Dia</StudentName>
<Muncipality>
<AreaCode>100</AreaCode>
<Areaname>GRAND</Areaname>
</Muncipality>
</Student>
<Student ID="201">
<StudentName>Liva</StudentName>
</Student>
</Students>
</Section>
<Section ID="7543466">
<SectioName>Section A</SectioName>
<Students>
<Student ID="300">
<StudentName>Zane</StudentName>
</Student>
<Student ID="301">
<StudentName>Susan</StudentName>
</Student>
</Students>
</Section>
</ClassDetail>
</ClassDetails>
</StudentDetail>
下面是XML的必需格式-
<StudentDetail>
<Student>
<SchoolName>SSHPS</SchoolName>
<SchoolEstablishedYear>1990</SchoolEstablishedYear>
<ClassStartedYear>1990</ClassStartedYear>
<SectionID>12345</SectionID>
<SectioName>Section A</SectioName>
<StudentID>1</StudentID>
<StudentName>John</StudentName>
<Address_HomeNumber>10</Address_HomeNumber>
<Address_StreetName>Avenue</Address_StreetName>
<Age> </Age>
<Muncipality_AreaCode></Muncipality_AreaCode>
<Muncipality_Areaname></Muncipality_Areaname>
</Student>
.

<Student>
<SchoolName>SSHPS</SchoolName>

<ClassStartedYear>1995</ClassStartedYear>
<SectionID>7543466</SectionID>
<SectioName>Section A</SectioName>
<StudentID>100</StudentID>

<Muncipality_AreaCode>100</Muncipality_AreaCode>
<Muncipality_Areaname>GRAND</Muncipality_Areaname>
</Student>
</StudentDetail>
我已经生成了XSL模板,由于其中存在一些错误,因此我无法加载该模板-
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output indent="yes" method="xml"/>
<xsl:template match="/">
<StudentDetail>
<xsl:for-each select="StudentDetail/ClassDetails">
<Student>
<SchoolName><xsl:value-of select="StudentDetail/SchoolName"/></SchoolName>
<SchoolEstablishedYear><xsl:value-of select="StudentDetail/SchoolEstablishedYear"/></SchoolEstablishedYear>
<ClassStartedYear><xsl:value-of select="StudentDetail/ClassDetails/ClassDetail/ClassStartedYear"/></ClassStartedYear>
<StudentID><xsl:value-of select="StudentDetail/ClassDetails/Section/@ID"/></StudentID>
<SectioName><xsl:value-of select="StudentDetail/ClassDetails/ClassDetail/Section/SectionName"/></SectioName>
<StudentID><xsl:value-of select="StudentDetail/ClassDetails/ClassDetail/Section/Students/Student/@ID"/></StudentID>
<StudentName><xsl:value-of select="StudentDetail/ClassDetails/ClassDetail/Section/Students/Student"/></StudentName>
<Address_HomeNumber><xsl:value-of select="StudentDetail/ClassDetails/ClassDetail/Section/Students/Student/Address/HomeNumber"/></Address_HomeNumber>
<Address_StreetName><xsl:value-of select="StudentDetail/ClassDetails/ClassDetail/Section/Students/Student/Address/StreetName"/></Address_StreetName>
<Age><xsl:value-of select="StudentDetail/ClassDetails/ClassDetail/Section/Students/Student/Age"/></Age>
<Muncipality_AreaCode><xsl:value-of select="StudentDetail/ClassDetails/ClassDetail/Section/Students/Student/Muncipality/AreaCode"/></Muncipality_AreaCode>
<Muncipality_Areaname><xsl:value-of select="StudentDetail/ClassDetails/ClassDetail/Section/Students/Student/Muncipality/Areaname"/></Muncipality_Areaname>
</Student>
</xsl:for-each>
</StudentDetail>
</xsl:template>
我是处理XML的新手,但对处理嵌套的XML却一无所知
解决方法
首先,令我惊讶的是,有人会把这种结构良好的输入转换为结构不良的输出。但是我们不在这里讨论。
其次,我对您“手动生成XSL”的说法感到困惑。我本以为您要么手动创建它,要么以编程方式生成它,目前尚不清楚是哪种情况。
第三,您已经告诉我们生成的XSL中存在“某些错误”,但是您没有告诉我们该错误是什么。我唯一看到的错误是xsl:stylesheet
元素缺少结束标记,这大概是一个错字。如果您遇到错误,请告诉我们错误是什么。
第四,似乎有一种更简单的方法。据我所知,您可以通过应用以下三个规则来获得所需的输出:
-
如果元素具有子元素,则只需处理其子元素
-
如果元素具有ID属性,请将
<X ID="x"/>
更改为<XID>x</XID>
,然后处理其子元素 -
如果元素具有文本节点子元素,则将其不变地复制。
第一个规则对应于默认的XSLT处理规则;其他两个规则可以在XSLT中简单地表示为:
<xsl:template match="*[@ID]">
<xsl:element name="{name()}ID">
<xsl:value-of select="@ID"/>
</xsl:element>
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="*[text()]">
<xsl:copy-of select="."/>
</xsl:template>
,
样式表的主要问题是您要为每个Student
创建一个ClassDetails
,而不是为每个Student
创建一个。
代替:
<xsl:for-each select="StudentDetail/ClassDetails">
<Student>
<!-- data -->
</Student>
</xsl:for-each>
您应该这样做:
<xsl:for-each select="StudentDetail/ClassDetails/ClassDetail/Section/Students/Student">
<Student>
<!-- data -->
</Student>
</xsl:for-each>
然后,在Student
元素内,您需要从祖先School
,ClassDetail
和Section
以及子元素的子元素中检索数据。当前的Student
节点。
为了最大程度地减少在树上反复导航的需要,我建议将祖先零件详细信息放入变量中并从那里访问它们:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/StudentDetail">
<xsl:copy>
<xsl:variable name="school-details" select="SchoolName | SchoolEstablishedYear"/>
<xsl:for-each select="ClassDetails/ClassDetail">
<xsl:variable name="class-details" select="ClassStartedYear"/>
<xsl:for-each select="Section">
<xsl:variable name="section-details">
<SectionID>
<xsl:value-of select="@ID"/>
</SectionID>
<xsl:copy-of select="SectioName"/>
</xsl:variable>
<xsl:for-each select="Students/Student">
<xsl:copy>
<xsl:copy-of select="$school-details | $class-details"/>
<xsl:copy-of select="$section-details"/>
<StudentID>
<xsl:value-of select="@ID"/>
</StudentID>
<xsl:copy-of select="StudentName"/>
<Address_HomeNumber>
<xsl:value-of select="Address/HomeNumber"/>
</Address_HomeNumber>
<Address_StreetName>
<xsl:value-of select="Address/StreetName"/>
</Address_StreetName>
<Age>
<xsl:value-of select="Age"/>
</Age>
<Muncipality_AreaCode>
<xsl:value-of select="Muncipality/AreaCode"/>
</Muncipality_AreaCode>
<Muncipality_Areaname>
<xsl:value-of select="Muncipality/Areaname"/>
</Muncipality_Areaname>
</xsl:copy>
</xsl:for-each>
</xsl:for-each>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
