问题描述

我有以下XML，并且要对其进行处理，以免在结果集中出现重复.我已经简化了问题，使其更易于理解.另外，如何将一个模板的结果用作另一模板的输入的一部分?

I have the following XML and I want to process it so that I do not get duplicates in the result set. I have simplified the problem to make it easier to understand. Also how can I use the results of one template as part of the input for another?

此:

<LINES xmlns:set="http://exslt.org/sets">
  <STDINSTRSEQ>0</STDINSTRSEQ>
  <STDINSTRSEQ>1</STDINSTRSEQ>
  <STDINSTRSEQ>2</STDINSTRSEQ>
</LINES>

是所需的结果. <STDINSTRSEQ>是应视为键的字段的名称.我在这里提供了示例数据.

is the desired result. <STDINSTRSEQ> is the name of the field that should be treated as the key. I have provided the sample data here.

推荐答案

如果我正确理解了您的要求，那么给出您的示例XML即可.

If I understand correctly what you are asking for, then given your sample XML this would work

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

  <xsl:template match="/">
    <xsl:apply-templates select="/PURCHASEORDER/LINES" />
  </xsl:template>

  <xsl:template match="LINES">
    <LINES xmlns:set="http://exslt.org/sets">
           <xsl:apply-templates select="LINE/STDINSTRSEQ[not(. = preceding::STDINSTRSEQ)]"/> 
    </LINES>
  </xsl:template>

  <xsl:template match="STDINSTRSEQ">
          <xsl:copy> <xsl:apply-templates/> </xsl:copy>
  </xsl:template>

</xsl:stylesheet>

一个优化的版本，它使用 <xsl:key> 进行过滤并提供独特的结果:

An optimized version that uses <xsl:key> to filter and provide unique results:

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

  <xsl:key name="STDIN" match="STDINSTRSEQ" use="./text()" />

  <xsl:template match="/">
    <xsl:apply-templates select="/PURCHASEORDER/LINES" />
  </xsl:template>

  <xsl:template match="LINES">
    <LINES xmlns:set="http://exslt.org/sets">
           <xsl:apply-templates select="LINE/STDINSTRSEQ[generate-id(.) = generate-id(key('STDIN', .))]"/>
    </LINES>
  </xsl:template>

  <xsl:template match="STDINSTRSEQ">
          <xsl:copy> <xsl:apply-templates/> </xsl:copy>
  </xsl:template>

</xsl:stylesheet>

这篇关于删除xsl中的重复项的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
