我有三个 xml 文件

            </Product>
        </Product>
    </Product>
</Products>

每个文件具有相同的产品（按 ./name），但具有不同的子产品（按 ./name），我需要将它们连接到一棵树中，每个产品/名称一个产品，包含所有子产品按照相同的规则，这样我就可以输出一种结构。

我找到了一个 xslt 方法，它将创建一个节点集，如下所示

    <xsl:variable name="step-output">
    <xsl:for-each select="/index/file">
        <xsl:copy-of select="document(.)" />
    </xsl:for-each>
</xsl:variable>
<xsl:variable name="step-products" select="exsl:node-set($step-output)//Products" />

但是，当我创建其他模板时，将按产品/名称创建三个产品，即塞浦路斯将出现三次。

有谁知道我要做什么？我的结果需要如下

        </Product>
    </Product>
</Products>

Each file has the same products (by ./name) but with differing sub products (by ./name) and I need to concatenate them into one tree with one product per product/name, containing all sub products on the same rules so that I can output one structure.

I have an xslt method found, that will create a node set as below

    <xsl:variable name="step-output">
    <xsl:for-each select="/index/file">
        <xsl:copy-of select="document(.)" />
    </xsl:for-each>
</xsl:variable>
<xsl:variable name="step-products" select="exsl:node-set($step-output)//Products" />

But this, when I create other templates will create three products by product/name, i.e. cyprus will turn up three times.

Does anyone know how to do what I'm after?? My result needs to be as follows

下面是一个可以完成这项工作的 XSLT 2.0 样式表：

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="2.0">

  <xsl:output indent="yes"/>

  <xsl:template match="/">
    <step>
      <Products>
        <xsl:for-each-group select="document(index/file)/step/Products/Product" group-by="Name">
          <Product UserTypeID="{@UserTypeID}">
            <Name><xsl:value-of select="current-grouping-key()"/></Name>
            <xsl:for-each-group select="current-group()/Product" group-by="Name">
              <xsl:sort select="current-grouping-key()"/>
              <Product UserTypeID="{@UserTypeID}">
                <Name><xsl:value-of select="current-grouping-key()"/></Name>
                <xsl:for-each select="current-group()/Product">
                  <xsl:sort select="Name"/>
                  <xsl:copy-of select="."/>
                </xsl:for-each>
              </Product>
            </xsl:for-each-group>
          </Product>
        </xsl:for-each-group>
      </Products>
    </step>
  </xsl:template>

</xsl:stylesheet>

您需要针对一个索引 XML 文档运行它，该文档的结构

<index>
  <file>test2010020803.xml</file>
  <file>test2010020804.xml</file>
  <file>test2010020805.xml</file>
</index>

列出了您想要处理的其他文件。

XSLT 2.0 样式表可以使用 Saxon 9 执行，它有 .NET 和 Java 版本，因此可以在任何地方运行其中至少有 Java 1.5 或 .NET 2.0 可用或可以安装。其他选项包括 AltovaXML 工具（仅限 Windows）和 格式塔。

如果您使用 XSLT 1.0，那么只要您有 exsl:node-set 或类似的支持，您就可以按如下方式进行操作：

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:exsl="http://exslt.org/common"
  exclude-result-prefixes="exsl"
  version="1.0">

  <xsl:output indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:key name="k1" match="step/Products/Product" use="Name"/>
  <xsl:key name="k2" match="step/Products/Product/Product" use="concat(../Name, '|', Name)"/>

  <xsl:template match="/">
    <xsl:variable name="rtf">
      <xsl:copy-of select="document(index/file)/*"/>
    </xsl:variable>
    <step>
      <Products>
        <xsl:for-each select="exsl:node-set($rtf)/step/Products/Product[generate-id() = generate-id(key('k1', Name)[1])]">
          <Product UserTypeID="{@UserTypeID}">
            <xsl:copy-of select="Name"/>
            <xsl:for-each select="key('k1', Name)/Product[generate-id() = generate-id(key('k2', concat(../Name, '|', Name))[1])]">
              <xsl:sort select="Name"/>
              <Product UserTypeID="{@UserTypeID}">
                <xsl:copy-of select="Name"/>
                <xsl:for-each select="key('k2', concat(../Name, '|', Name))/Product">
                  <xsl:sort select="Name"/>
                  <xsl:copy-of select="."/>
                </xsl:for-each>
              </Product>
            </xsl:for-each>
          </Product>
        </xsl:for-each>
      </Products>
    </step>
  </xsl:template>

</xsl:stylesheet>

键将如下所示：

  <xsl:key name="k1" match="step/Products/Product" use="Name"/>

  <xsl:key name="k2" match="step/Products/Product/Product" use="concat(../Name, '|', Name)"/>

  <xsl:key name="k3" match="step/Products/Product/Product/Product"
                     use="concat(../../Name, '|', ../Name, '|', Name)"/>

  <xsl:key name="k4" 
           match="step/Products/Product/Product/Product/Product"
           use="concat(../../../Name, '|', ../../Name, '|', ../Name, '|', Name)"/>

  <xsl:key name="k5" 
           match="step/Products/Product/Product/Product/Product/Product"
           use="concat(../../../../Name, '|', ../../../Name, '|', ../../Name, '|', ../Name, '|', Name)"/>

  <xsl:key name="k6" 
           match="step/Products/Product/Product/Product/Product/Product/Product"
           use="concat(../../../../../Name, '|', ../../../../Name, '|', ../../../Name, '|', ../../Name, '|', ../Name, '|', Name)"/>

这都是在论坛编辑器中直接键入的，因此可能会有错误。

Here is an XSLT 2.0 stylesheet that should do the job:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="2.0">

  <xsl:output indent="yes"/>

  <xsl:template match="/">
    <step>
      <Products>
        <xsl:for-each-group select="document(index/file)/step/Products/Product" group-by="Name">
          <Product UserTypeID="{@UserTypeID}">
            <Name><xsl:value-of select="current-grouping-key()"/></Name>
            <xsl:for-each-group select="current-group()/Product" group-by="Name">
              <xsl:sort select="current-grouping-key()"/>
              <Product UserTypeID="{@UserTypeID}">
                <Name><xsl:value-of select="current-grouping-key()"/></Name>
                <xsl:for-each select="current-group()/Product">
                  <xsl:sort select="Name"/>
                  <xsl:copy-of select="."/>
                </xsl:for-each>
              </Product>
            </xsl:for-each-group>
          </Product>
        </xsl:for-each-group>
      </Products>
    </step>
  </xsl:template>

</xsl:stylesheet>

You need to run it against an index XML document with the structure

<index>
  <file>test2010020803.xml</file>
  <file>test2010020804.xml</file>
  <file>test2010020805.xml</file>
</index>

that lists the other files you want to process.

XSLT 2.0 stylesheets can be executed with Saxon 9 which comes in a .NET and a Java version so it runs everywhere where either at least Java 1.5 or .NET 2.0 is available or can be installed. Other options are AltovaXML tools (Windows only) and Gestalt.

If you are tied to XSLT 1.0 then you can do it as follows, as long as you have exsl:node-set or similar support:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:exsl="http://exslt.org/common"
  exclude-result-prefixes="exsl"
  version="1.0">

  <xsl:output indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:key name="k1" match="step/Products/Product" use="Name"/>
  <xsl:key name="k2" match="step/Products/Product/Product" use="concat(../Name, '|', Name)"/>

  <xsl:template match="/">
    <xsl:variable name="rtf">
      <xsl:copy-of select="document(index/file)/*"/>
    </xsl:variable>
    <step>
      <Products>
        <xsl:for-each select="exsl:node-set($rtf)/step/Products/Product[generate-id() = generate-id(key('k1', Name)[1])]">
          <Product UserTypeID="{@UserTypeID}">
            <xsl:copy-of select="Name"/>
            <xsl:for-each select="key('k1', Name)/Product[generate-id() = generate-id(key('k2', concat(../Name, '|', Name))[1])]">
              <xsl:sort select="Name"/>
              <Product UserTypeID="{@UserTypeID}">
                <xsl:copy-of select="Name"/>
                <xsl:for-each select="key('k2', concat(../Name, '|', Name))/Product">
                  <xsl:sort select="Name"/>
                  <xsl:copy-of select="."/>
                </xsl:for-each>
              </Product>
            </xsl:for-each>
          </Product>
        </xsl:for-each>
      </Products>
    </step>
  </xsl:template>

</xsl:stylesheet>

The keys would look like this:

  <xsl:key name="k1" match="step/Products/Product" use="Name"/>

  <xsl:key name="k2" match="step/Products/Product/Product" use="concat(../Name, '|', Name)"/>

  <xsl:key name="k3" match="step/Products/Product/Product/Product"
                     use="concat(../../Name, '|', ../Name, '|', Name)"/>

  <xsl:key name="k4" 
           match="step/Products/Product/Product/Product/Product"
           use="concat(../../../Name, '|', ../../Name, '|', ../Name, '|', Name)"/>

  <xsl:key name="k5" 
           match="step/Products/Product/Product/Product/Product/Product"
           use="concat(../../../../Name, '|', ../../../Name, '|', ../../Name, '|', ../Name, '|', Name)"/>

  <xsl:key name="k6" 
           match="step/Products/Product/Product/Product/Product/Product/Product"
           use="concat(../../../../../Name, '|', ../../../../Name, '|', ../../../Name, '|', ../../Name, '|', ../Name, '|', Name)"/>

That is all typed directly here in the forum editor so could have bugs.

编辑文本来创建文件是可行的，但可能难以维护。

最简单的方法是将所有 3 个文件的 XML 解析为对象形式。以编程方式将对象添加到单个父节点下，然后重新生成新的 XML 文件。

您的环境是否使其成为可接受的解决方案？

Editing the text to create your files will work, but may be hard to maintain.

The easiest way would be to parse the XML of all 3 files into object form. Programmatically add the objects under a single parent node then regenerate a new XML file.

Does your environment make this an acceptable solution?
