如何在我的 XSLT 文本输出中包含节点 XML? [英] How to include the node XML in my XSLT text output?

问题描述

我正在尝试使用 XSLT(用于批量加载到 Postgres)将 XML 文件转换为平面的、以竖线分隔的文件.我希望输出中的最后一列是节点的实际 XML(用于额外的后处理和调试).例如:

I'm trying to convert an XML file into a flat, pipe-delimited file with XSLT (for bulk-loading into Postgres). I would like the last column in my output to be the actual XML of the node (for additional post-processing and debugging). For example:

<Library>
  <Book id="123">
    <Title>Python Does Everythig</Title>
    <Author>Smith</Author>
  </Book>

  <Book id="456">
    <Title>Postgres is Neat</Title>
    <Author>Wesson</Author>
  </Book>
</Library>

应该生成

Python Does Everything|Smith|<Book id="123"><Title>Python Does Everythig</Title>Author>Smith</Author></Book>
Postgres is Neat|Wesson|<Book id="456"><Title>Postgres is Neat</Title><Author>Wesson</Author></Book>

我当前的 XSL 是

My current XSL is

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:strip-space elements="*" />
  <xsl:output method="text" omit-xml-declaration="yes" indent="no" /> 
  <xsl:template match="//Book">
    <xsl:value-of select="Title" />
    <xsl:text>|</xsl:text>
    <xsl:value-of select="Author" />

    <!-- put in the newline -->
    <xsl:text>&#xa;</xsl:text>
  </xsl:template>
</xsl:stylesheet>    

推荐答案

我不确定这是否是推荐的解决方案，但您可以尝试将输出方法设置为 xml，然后仅使用 xsl:copy-of 函数.

I am not sure if this is a recommended solution, but you could try setting the output method to xml, and then just using the xsl:copy-of function.

所以，下面的 XSLT

So, the following XSLT

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
  <xsl:strip-space elements="*" /> 
  <xsl:output method="xml" omit-xml-declaration="yes" indent="no" />  
  <xsl:template match="//Book"> 
    <xsl:value-of select="Title" /> 
    <xsl:text>|</xsl:text> 
    <xsl:value-of select="Author" /> 
    <xsl:text>|</xsl:text>  
    <xsl:copy-of select="." />
    <!-- put in the newline --> 
    <xsl:text>&#xa;</xsl:text> 
  </xsl:template> 
</xsl:stylesheet>  

应用于您的示例 XML 时，生成以下输出

When applied to your sample XML, generates the following output

Python Does Everythig|Smith|<Book id="123"><Title>Python Does Everythig</Title><Author>Smith</Author></Book>
Postgres is Neat|Wesson|<Book id="456"><Title>Postgres is Neat</Title><Author>Wesson</Author></Book>
