需要写一个xslt来将xml转换为带有特定数据的csv

问题描述 投票：0回答：2

我正在尝试编写一个 xslt，它从 xml 创建一个 csv。我需要创建一个标头字段映射，使标头与数据匹配。 这是一个示例 xml

  <headerFieldsMap>
    <BusinessUnit>Business Unit Code</BusinessUnit>
    <CompanyName>Business Unit Desct</CompanyName>
    <DeptDescr>Department Description</DeptDescr>
    <DeptId>Department</DeptId>
    <DescrShort>Posting Job Title</DescrShort>
    <Description>Working Position Description</Description>
    <JobFamily>Category</JobFamily>
    <PositionNbr>Position-Nbr</PositionNbr>
    <StdHoursFreq>Standard hours Frequency</StdHoursFreq>
    <TotalWorkingHours>Standard Hours</TotalWorkingHours>
  </headerFieldsMap>
  <psPositions>
    <position>
      <LocationPostal>06511</LocationPostal>
      <ConfidentialFlag>N</ConfidentialFlag>
      <DeptDescr>New Haven EMU Shop</DeptDescr>
      <Description>Carman E Rate</Description>
      <RegTemp>R</RegTemp>
      <SalAdminPlan>TWUR</SalAdminPlan>
      <JobCodeSetid>SHARE</JobCodeSetid>
      <LocationCountry>US</LocationCountry>
      <Remote>N</Remote>
      <Step>0</Step>
      <SalaryRangeTo>0</SalaryRangeTo>
      <PositionNbr>01000333</PositionNbr>
      <SalaryRangeFrom>0</SalaryRangeFrom>
      <EffStatus>A</EffStatus>
      <FullPartTime>F</FullPartTime>
      <PositionStatus>Approved</PositionStatus>
      <LocationSetId>SHARE</LocationSetId>
      <CompanyName>Metro-North Railroad</CompanyName>
      <RemainingHeadCount>0</RemainingHeadCount>
      <PayFrequency>H</PayFrequency>
      <JobCode>26448E</JobCode>
      <RegRegion>USA</RegRegion>
      <Shift>2</Shift>
      <ReportsToPos>01000474</ReportsToPos>
      <DeptIdSetId>MNCRR</DeptIdSetId>
      <TotalWorkingHours>40</TotalWorkingHours>
      <DescrShort>Carman E R</DescrShort>
      <StdHoursFreq>W</StdHoursFreq>
      <LocationCode>NEW HAVEN</LocationCode>
      <Effdt>2023-02-21</Effdt>
      <LocationDescr>98 Union Street</LocationDescr>
      <LocationCity>New Haven</LocationCity>
      <Grade>004</Grade>
      <JobFamily>Transportation Operations</JobFamily>
      <DeptId>44302</DeptId>
      <LastUpdDtTm>2023-02-21T19:12:05Z</LastUpdDtTm>
      <LocationRegion>CT</LocationRegion>
      <ReportsToEmail>[email protected]</ReportsToEmail>
      <PayCurrency>USD</PayCurrency>
      <MaxHeadCount>1</MaxHeadCount>
      <BusinessUnit>MNCRR</BusinessUnit>
      <JobFamilyCode>TRNOPS</JobFamilyCode>
      <CompanyCode>MNR</CompanyCode>
      <CurrHeadCount>1</CurrHeadCount>
    </position>
 </psPositions>
</root>

csv 或输出应如下所示

Business Unit Code,Business Unit Desct,Department Description,Department,Posting Job Title,Working Position Description,Category,Position-Nbr,Standard hours Frequency,Standard Hours
MNCRR,Metro-North Railroad,New Haven EMU Shop,44302,Carman E R,Carman E Rate,Transportation Operations,01000333,W,40
MTAHQ,MTA Headquarters,Division of Management /Budget,400300,SR FINANCI,Sr Financial Analyst - Budgets,Finance/Accounting,01055644,W,37.5

请注意，数据仅具有字段中提到的字段的值。中的字段可能会有所不同，只能输入 2 个字段，数据应相应显示。

我现在的xslt是这个

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="text" encoding="UTF-8"/>

  <xsl:variable name="delimiter" select="','"/>

  <xsl:template match="/">
    <!-- Header row -->
    <xsl:for-each select="root/headerFieldsMap/*">
      <xsl:value-of select="."/>
      <xsl:if test="position() != last()">
        <xsl:value-of select="$delimiter"/>
      </xsl:if>
    </xsl:for-each>
    <xsl:text>&#10;</xsl:text>

    <!-- Data rows -->
    <xsl:for-each select="root/psPositions/position">
      <xsl:for-each select="*">
        <xsl:variable name="fieldName" select="name()"/>
        <xsl:variable name="fieldValue" select="."/>

        <!-- If the field value is StdHoursFreq and it's equal to "W", replace it with "Weekly" -->
        <xsl:choose>
          <xsl:when test="$fieldName = 'StdHoursFreq' and $fieldValue = 'W'">
            <xsl:text>Weekly</xsl:text>
          </xsl:when>
          <xsl:otherwise>
            <xsl:value-of select="$fieldValue"/>
          </xsl:otherwise>
        </xsl:choose>

        <xsl:if test="position() != last()">
          <xsl:value-of select="$delimiter"/>
        </xsl:if>
      </xsl:for-each>
      <xsl:text>&#10;</xsl:text>
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

但是这个打印出xml中的所有数据。我只需要标题中提到的数据。 XSLT 标准：1.0

上面的 xslt 生成如下所示的输出。它不应该包含不在标题中的字段的数据，例如“[email protected]”不应该存在，因为“ReportsToEmail”不在标题中。

Business Unit Code,Business Unit Desct,Department Description,Department,Posting Job Title,Working Position Description,Category,Position-Nbr,Standard hours Frequency,Standard Hours

我只需要标题中提到的数据

按照以下方式尝试：

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" encoding="UTF-8"/>

<xsl:key name="row-data" match="position/*" use="concat(name(), generate-id(..))" />

<xsl:template match="/root">
    <xsl:variable name="cols" select="headerFieldsMap/*"/>
    <!-- header row-->
    <xsl:for-each select="$cols">
        <xsl:value-of select="."/>
        <xsl:if test="position()!=last()">,</xsl:if>
    </xsl:for-each>
    <xsl:text>&#10;</xsl:text>
    <!-- data rows-->
    <xsl:for-each select="psPositions/position">
        <xsl:variable name="row-id" select="generate-id()"/>
        <xsl:for-each select="$cols">
            <xsl:value-of select="key('row-data', concat(name(), $row-id))"/>
            <xsl:if test="position()!=last()">,</xsl:if>
        </xsl:for-each>
        <xsl:text>&#10;</xsl:text>
    </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

请注意，从您输入的 XML 中获得的结果与您显示的结果大不相同。尽管如此，样式表符合您问题中提出的逻辑（至少我理解的方式）。

要将 

W
更改为 
Weekly
，您可以这样做：

        <xsl:for-each select="$cols">
            <xsl:variable name="value" select="key('row-data', concat(name(), $row-id))" />
            <xsl:choose>
                <xsl:when test="name() = 'StdHoursFreq' and $value = 'W'">Weekly</xsl:when>
                <xsl:otherwise>
                    <xsl:value-of select="$value"/>
                </xsl:otherwise>
            </xsl:choose>
            <xsl:if test="position()!=last()">,</xsl:if>
        </xsl:for-each>

请尝试以下 XSLT。

XSLT

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

    <xsl:variable name="delimiter" select="','"/>

    <xsl:template match="/root">
        <!-- Header row -->
        <xsl:for-each select="headerFieldsMap/*">
            <xsl:value-of select="."/>
            <xsl:if test="position() != last()">
                <xsl:value-of select="$delimiter"/>
            </xsl:if>
        </xsl:for-each>
        <xsl:text>&#xA;</xsl:text>

        <!-- Data rows -->
        <xsl:for-each select="psPositions/position">
            <xsl:variable name="row" select="."/>
            <xsl:for-each select="/root/headerFieldsMap/*">
                <xsl:variable name="fieldName" select="local-name()"/>
                <xsl:variable name="fieldValue" select="."/>

                <!-- If the field value is StdHoursFreq and it's equal to "W", replace it with "Weekly" -->
                <xsl:choose>
                    <xsl:when test="$row/*[local-name()=$fieldName] = 'W' and $row/*[local-name()='StdHoursFreq']">
                        <xsl:text>Weekly</xsl:text>
                    </xsl:when>
                    <xsl:when test="$fieldName = 'DescrShort'">
                        <xsl:value-of select="$row/*[local-name()='LocationPostal']"/>
                    </xsl:when>
                    <xsl:otherwise>
                        <xsl:value-of select="$row/*[local-name()=$fieldName]"/>
                    </xsl:otherwise>
                </xsl:choose>

                <xsl:if test="position() != last()">
                    <xsl:value-of select="$delimiter"/>
                </xsl:if>
            </xsl:for-each>
            <xsl:text>&#xA;</xsl:text>
        </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>
