Question

我在这里找到了一些代码，这是一个不错的开始，但它与我正在寻找的有点不同，我不知道如何继续。我想要做的是复制整个XML文件，通过基于多个分隔符拆分Author元素来创建新元素，并且还删除原始的“Author”元素名称。每个作者“set”由分号分隔，并以回车结束或仅仅是记录4中的回车结束。任何帮助将不胜感激。我是一个XSLT新手，对提供的解决方案的任何解释都会很棒，因为我想要了解解决方案，而不仅仅是让它工作。感谢。

代码：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:e="http://localhost">
<xsl:output indent="yes"/>
<e:e>AuthorName</e:e>
<e:e>AuthorLocation</e:e>
<e:e>AuthorPhone</e:e>
<xsl:variable name="vElement" select="document('')/*/e:*"/>
<xsl:template match="node()|@*">
    <xsl:copy>
        <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
</xsl:template>
<xsl:template match="Author/text()" name="tokenizer">
    <xsl:param name="pString" select="string()"/>
    <xsl:param name="pPosition" select="1"/>
    <xsl:if test="$pString">
        <xsl:element name="{$vElement[$pPosition]}">
            <xsl:value-of select="normalize-space(substring-before(concat($pString,';'),';'))"/>
        </xsl:element>
        <xsl:call-template name="tokenizer">
            <xsl:with-param name="pString" select="substring-after($pString,';')"/>
            <xsl:with-param name="pPosition" select="$pPosition + 1"/>
        </xsl:call-template>
    </xsl:if>
</xsl:template>

Answer 1

此XSLT 2.0转换：

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:variable name="vAuthorDataNames" select=
  "'AuthorName', 'AuthorLocation', 'AuthorPhone'"/>

 <xsl:template match="node()|@*">
  <xsl:copy>
   <xsl:apply-templates select="node()|@*"/>
  </xsl:copy>
 </xsl:template>

 <xsl:template match="Author">
  <xsl:variable name="vAuthors" select="tokenize(., '(\n(\r?))\s*')"/>

  <xsl:for-each select="$vAuthors[normalize-space(.)]">
   <xsl:variable name="vAuthorData" select="tokenize(., ';\s*')"/>

   <xsl:for-each select="$vAuthorData">
    <xsl:variable name="vPos" select="position()"/>

    <xsl:element name="{$vAuthorDataNames[$vPos]}">
     <xsl:value-of select="."/>
    </xsl:element>
   </xsl:for-each>
  </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>

应用于提供的XML文档时：

<RECORD_SET>
    <RECORD NUM="1">
        <Title>Title1</Title>
        <Author>Author Name 1; Author Location 1; Author Phone Number 1</Author>
        <Date>11/20/1976</Date>
    </RECORD>
    <RECORD NUM="2">
        <Title>Title2</Title>
        <Author>Author Name 2; Author Location 2; Author Phone Number 2
        Author Name 3; Author Location 3; Author Phone Number 3
        Author Name 4; Author Location 4; Author Phone Number 4</Author>
        <Date>10/20/2001</Date>
    </RECORD>
    <RECORD NUM="3">
        <Title>Title3</Title>
        <Author>Author Name 5; Author Location 5; Author Phone Number 5
        Author Name 6; Author Location 6; Author Phone Number 6</Author>
        <Date>09/18/1966</Date>
    </RECORD>
    <RECORD NUM="4">
        <Title>Title4</Title>
        <Author>Author Name 7
        Author Name 8</Author>
        <Date>01/18/1956</Date>
    </RECORD>
</RECORD_SET>

会产生想要的正确结果：

<RECORD_SET>
   <RECORD NUM="1">
      <Title>Title1</Title>
      <AuthorName>Author Name 1</AuthorName>
      <AuthorLocation>Author Location 1</AuthorLocation>
      <AuthorPhone>Author Phone Number 1</AuthorPhone>
      <Date>11/20/1976</Date>
   </RECORD>
   <RECORD NUM="2">
      <Title>Title2</Title>
      <AuthorName>Author Name 2</AuthorName>
      <AuthorLocation>Author Location 2</AuthorLocation>
      <AuthorPhone>Author Phone Number 2</AuthorPhone>
      <AuthorName>Author Name 3</AuthorName>
      <AuthorLocation>Author Location 3</AuthorLocation>
      <AuthorPhone>Author Phone Number 3</AuthorPhone>
      <AuthorName>Author Name 4</AuthorName>
      <AuthorLocation>Author Location 4</AuthorLocation>
      <AuthorPhone>Author Phone Number 4</AuthorPhone>
      <Date>10/20/2001</Date>
   </RECORD>
   <RECORD NUM="3">
      <Title>Title3</Title>
      <AuthorName>Author Name 5</AuthorName>
      <AuthorLocation>Author Location 5</AuthorLocation>
      <AuthorPhone>Author Phone Number 5</AuthorPhone>
      <AuthorName>Author Name 6</AuthorName>
      <AuthorLocation>Author Location 6</AuthorLocation>
      <AuthorPhone>Author Phone Number 6</AuthorPhone>
      <Date>09/18/1966</Date>
   </RECORD>
   <RECORD NUM="4">
      <Title>Title4</Title>
      <AuthorName>Author Name 7</AuthorName>
      <AuthorName>Author Name 8</AuthorName>
      <Date>01/18/1956</Date>
   </RECORD>
</RECORD_SET>

<强>解释：

正确使用标准XSLT函数 tokenize() 和 normalize-space() 。

XSLT基于多个分隔符将元素拆分为新元素
