标签： xslt xslt-2.0

下面是我用于将xml转换为平面文件的xsl，它还满足各种其他所需条件。

<xsl:stylesheet version="1.0"      xmlns:xsl="http://www.w3.org/1999/XSL/Transform"      xmlns:ext="http://exslt.org/common">
  <xsl:output omit-xml-declaration="yes" indent="yes"/>
  <xsl:strip-space elements="*"/>
  <xsl:variable name="vrtfDefaults">
    <termCat/>
    <termVocab/>
  </xsl:variable>
  <xsl:variable name="vDefaults" select="ext:node-set($vrtfDefaults)"/>
  <xsl:variable name="vQ">"</xsl:variable>
  <xsl:template match="Zthes">
    <xsl:text>"HDR";"PIGLSSTD";"20120112045620";"F"</xsl:text>
    <xsl:apply-templates/>
    <xsl:text>&#xA;"FTR";</xsl:text>
    <xsl:value-of select="count(term)+count(term/termCategory)+count(term/relation/termVocabulary)"/>
  </xsl:template>
  <xsl:template match="term">
    <xsl:variable name="vTerm" select="."/>
    <xsl:variable name="vRow1" select="'&#xA;&quot;GL&quot;;'"/>
    <xsl:for-each select="termCategory | $vDefaults/termCat[not($vTerm/termCategory)]">
      <xsl:variable name="vRow2" select="concat($vRow1, $vQ, ., $vQ, ';')"/>
      <xsl:for-each select="$vTerm/termVocabulary | $vDefaults/termCat[not($vTerm/termVocabulary)]">
        <xsl:variable name="vRow3" select="concat($vRow2, $vQ, ., $vQ, ';')"/>
        <xsl:for-each select="$vTerm/relation/termVocabulary | $vDefaults/termCat[not($vTerm/relation/termVocabulary)]">
          <xsl:value-of select="concat($vRow3, $vQ, ., $vQ, ';')"/>
        </xsl:for-each>
      </xsl:for-each>
    </xsl:for-each>
  </xsl:template>
  <xsl:template match="text()"/>
</xsl:stylesheet>

示例XML如下所示：

<?xml version="1.0" encoding="utf-8"?>
<GetSavedReportResponse>
  <ResponseType>Success</ResponseType>
  <FileModifiedDateTime>2012-01-03T17:05:04</FileModifiedDateTime>
  <FileSizeBytes>7816</FileSizeBytes>
  <FileDataFormat>XML</FileDataFormat>
  <FileData>
    <Zthes>
      <term>
        <termId>49555</termId>
        <termUpdate>add</termUpdate>
        <termName>Active Personnel</termName>
        <termVocabulary>People Status Global Term1</termVocabulary>
        <termVocabulary>Global People Status Term1</termVocabulary>
        <termCategory>PDA Term1</termCategory>
        <termCategory>PDI Term1</termCategory>
        <termCategory>GLB Term1</termCategory>
        <relation weight="100">
          <termId>49556</termId>
          <relationType>EQ Term1</relationType>
          <termName>term name Term1</termName>
          <termVocabulary>term vocabulary Term1</termVocabulary>
        </relation>
        <relation weight="100">
          <termId>49557</termId>
          <relationType>BT</relationType>
          <termName>General Active Personnel</termName>
          <termVocabulary>People Status Global Updated</termVocabulary>
        </relation>
      </term>
      <term>
        <termId>49556</termId>
        <termUpdate>add</termUpdate>
        <termName>Leave of Absence Personnel</termName>
        <termVocabulary>People Status Global Term2</termVocabulary>
        <termCategory>GLB Term2</termCategory>
        <termCategory>PDI Term2</termCategory>
        <relation weight="100">
          <relationType>BT</relationType>
          <termId>49554</termId>
          <termName>General Non-Active Personnel Term2</termName>
          <termVocabulary>People Status Global Term2</termVocabulary>
        </relation>
      </term>
    </Zthes>
  </FileData>
</GetSavedReportResponse>

除了页脚中的行数之外，一切正常，这应该是平面文件中的行数（不包括页眉和页脚）。
