XSLT 2.0 将 CSV 转换为 XML 格式

问题描述

我正在尝试将 CSV(逗号分隔文件)转换为 XML.为此，我正在编写一个 XSLT 模板，这是我第一次尝试 XSLT...

I am are trying to convert an CSV (comma separated file) into XML. For this, I am coding an XSLT template and this is my 1st try at XSLT...

CSV 示例:

ClaimRef,HandlerRef,ClaimType,Date,Area,SettleDate,ClaimStatus,ClaimantName
1,1/1,Liability,08-12-2013,US,23-05-2014,Closed,Mark
2,1/2,Liability,08-10-2013,UK,23-02-2014,Closed,John

所需的 XML 输出格式:

 <Claims>
     <Claim>
      <ClaimRef></ClaimRef>
      <HandlerRef></HandlerRef>
      <ClaimType></ClaimType>
      <Date></Date>
      <Area></Area>
      <SettleDate></SettleDate>
      <ClaimStatus></ClaimStatus>
      <ClaimantName></ClaimantName>
     </Claim>
    </Claims>

我使用了 http://blogs.msdn.com/b/kaevans/archive/2003/04/17/5780.aspx 作为初始开始和 http:///xslttest.appspot.com/ 来测试结果.但是这篇文章提到了如何获取<row><elem>等的值.

I used http://blogs.msdn.com/b/kaevans/archive/2003/04/17/5780.aspx as initial start and http://xslttest.appspot.com/ to test the results. But this article mentions how to get the values as <row><elem>, etc.

请您指导我如何编写 XSLT 以根据示例 CSV 数据生成上述 XML.

Please can you guide me how to code an XSLT to generate above XML based on sample CSV data.

推荐答案

这是一个 XSLT 2.0 选项...

Here's an XSLT 2.0 option...

CSV 输入(在 csv-uri 参数中引用的 so.csv.)

CSV Input (so.csv referenced in the csv-uri param.)

ClaimRef,HandlerRef,ClaimType,Date,Area,SettleDate,ClaimStatus,ClaimantName
1,1/1,Liability,08-12-2013,US,23-05-2014,Closed,Mark
2,1/2,Liability,08-10-2013,UK,23-02-2014,Closed,John

XSLT 2.0(使用格式良好的虚拟 XML 文档或样式表本身作为输入或指定 csv2xml 作为初始模板.)

XSLT 2.0 (Use either a well-formed dummy XML doc or the stylesheet itself as input or specify csv2xml as the initial template.)

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs">

    <xsl:strip-space elements="*"/>

    <xsl:param name="csv-encoding" as="xs:string" select="'iso-8859-1'"/>
    <xsl:param name="csv-uri" as="xs:string" select="'file:///C:/Users/dhaley/Desktop/so.csv'"/>

    <xsl:template match="/" name="csv2xml">
        <Claims>
            <xsl:choose>
                <xsl:when test="unparsed-text-available($csv-uri, $csv-encoding)">
                    <xsl:variable name="csv" select="unparsed-text($csv-uri, $csv-encoding)"/>
                    <!--Get Header-->
                    <xsl:variable name="header-tokens" as="xs:string*">

                </xsl:when>
                <xsl:otherwise>
                    <xsl:variable name="error">
                        <xsl:text>Error reading "</xsl:text>
                        <xsl:value-of select="$csv-uri"/>
                        <xsl:text>" (encoding "</xsl:text>
                        <xsl:value-of select="$csv-encoding"/>
                        <xsl:text>").</xsl:text>
                    </xsl:variable>

            </xsl:choose>
        </Claims>
    </xsl:template>

</xsl:stylesheet>

XML 输出

这是相同的示例，但使用变量而不是外部 CSV 文件.您可以使用此 XSLT 在其他支持 XSLT 2.0 的在线测试工具中进行测试.

Here is the same example, but using a variable instead of an external CSV file. You can use this XSLT to test in other online test tools that support XSLT 2.0.
