我一直在试图合并books.xml中的所有文本节点,如果它们的属性值匹配的话。并且这些值768,16通过任何定界符来分隔(EX:等。)合并XSLT中的文本节点

这里是烃源XML:

这是XSLT我一直在努力:

<?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:xs="http://www.w3.org/2001/XMLSchema" 
    exclude-result-prefixes="xs" 
    version="2.0"> 
    <xsl:output method="xml" indent="yes"/> 
    <xsl:key name="Dbook" match="book" use="@id"/> 

    <xsl:template match="/catalog"> 
     <xsl:copy> 
     <xsl:for-each select="book[count(. | key('Dbook', @id)[1])=1]"> 
      <xsl:copy> 
      <xsl:copy-of select="@*"/> 
       <xsl:for-each select="key('Dbook',@id)">    
        <xsl:variable name="author" select="author"/> 
        <xsl:variable name="title" select="title"/> 
        <xsl:variable name="genre" select="genre"/> 
        <xsl:variable name="price" select="price"/> 
        <xsl:variable name="publish_date" select="publish_date"/> 
        <xsl:variable name="description" select="description"/> 
        <xsl:variable name="null"/> 

        <xsl:copy-of select="concat($author,$null)"/> 
        <xsl:copy-of select="concat($title,$null)"/>

请选择任一XSLT 1.0或2.0,而不是两个 - 电除尘器。当你问到分组时。在XSLT 2.0中,使用'xsl:for-each-group'很容易实现分组。使用'xsl:value-of'和'separator'属性合并文本节点同样是微不足道的。 - 请注意,您显示的输出无法生成,因为在XML中不允许使用未转义的&&字符。 –

这是一个与您以前的问题非常相似的问题,所以也许您应该从接受答案开始,然后尝试使其适应您的新要求,并在遇到困难时向我们显示您的尝试。顺便说一句,如果你想要的输出应该是XML,然后分隔符需要转义为' Gambardella,马修& Galos,迈克& Corets,伊娃' –

@ michael.hor257k我想和XSLT 1.0实现它即使我没有非转义性地获得它,我也没关系 –

在XSLT 1.0一个简单的(即使乏味)的解决方案是这样的:

XSLT 1.0

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

<xsl:key name="Dbook" match="book" use="@id"/> 
<xsl:variable name="separator" select="' &amp; '" /> 

<xsl:template match="/catalog"> 
    <xsl:copy> 
     <xsl:for-each select="book[count(. | key('Dbook', @id)[1])=1]"> 
      <xsl:copy> 
       <xsl:copy-of select="@*"/> 
       <xsl:variable name="group" select="key('Dbook', @id)" /> 
       <author> 
        <xsl:for-each select="$group"> 
         <xsl:value-of select="author"/> 
         <xsl:if test="position()!=last()"> 
          <xsl:value-of select="$separator"/> 
         </xsl:if> 
        </xsl:for-each> 
       </author> 
       <title> 
        <xsl:for-each select="$group"> 
         <xsl:value-of select="title"/> 
         <xsl:if test="position()!=last()"> 
          <xsl:value-of select="$separator"/> 
         </xsl:if> 
        </xsl:for-each> 
       </title> 

       <!-- add more child elements here --> 

      </xsl:copy> 
     </xsl:for-each> 
    </xsl:copy> 
</xsl:template> 

</xsl:stylesheet> 

结果

<?xml version="1.0" encoding="UTF-8"?> 
<catalog> 
    <book id="bk101"> 
    <author>Gambardella, Matthew &amp; Corets, Eva &amp; Galos, Mike</author> 
    <title>XML Developer's Guide &amp; Oberon's Legacy &amp; Visual Studio 7: A Comprehensive Guide</title> 
    </book> 
    <book id="bk102"> 
    <author>Ralls, Kim &amp; Corets, Eva</author> 
    <title>Midnight Rain &amp; The Sundered Grail</title> 
    </book> 
    <book id="bk103"> 
    <author>Corets, Eva</author> 
    <title>Maeve Ascendant</title> 
    </book> 
</catalog> 

为了消除代码为一本书的每个子属性的重复,你可以定义另一个密钥,并用它如下:

XSLT 1.0

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

<xsl:key name="Dbook" match="book" use="@id"/> 
<xsl:key name="book-property" match="book/*" use="concat(../@id, '|', name())"/> 

<xsl:variable name="separator" select="' &amp; '" /> 

<xsl:template match="/catalog"> 
    <xsl:copy> 
     <xsl:for-each select="book[count(. | key('Dbook', @id)[1])=1]"> 
      <xsl:copy> 
       <xsl:copy-of select="@*"/> 
       <xsl:for-each select="*"> 
        <xsl:copy> 
         <xsl:for-each select="key('book-property', concat(../@id, '|', name()))"> 
          <xsl:value-of select="."/> 
          <xsl:if test="position()!=last()"> 
           <xsl:value-of select="$separator"/> 
          </xsl:if> 
         </xsl:for-each> 
        </xsl:copy> 
       </xsl:for-each>    
      </xsl:copy> 
     </xsl:for-each> 
    </xsl:copy> 
</xsl:template> 

</xsl:stylesheet>
