我正在处理一个XSLT，它将输出一个XSLT，我们的安装程序将使用它来更新已安装的XML配置文件。

我的第一个XSLT看起来像这样：

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:outxsl="outputsasxsl" exclude-result-prefixes="outxsl">
  <xsl:output method="xml" indent="yes" />

  <xsl:namespace-alias result-prefix="xsl" stylesheet-prefix="outxsl"/>

  <!-- XsltArgumentList parameters-->
  <xsl:param name="parameter1">default1</xsl:param>
  <xsl:param name="parameter2">default2</xsl:param>
  <xsl:param name="parameter3">default3</xsl:param>
  <xsl:param name="parameter4">default4</xsl:param>
  <xsl:param name="parameter5">default5</xsl:param>
  <xsl:param name="parameter6">default6</xsl:param>

  <xsl:template match="/">
    <outxsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <outxsl:output method="xml" indent="yes" />

      <!-- Output all nodes & attributes for all Elements -->
      <outxsl:template match="/Element/Elements/Element">
        <!-- Copy all attributes and nodes -->
        <outxsl:copy-of select="@* | node()" />

        <!-- Output the new configuration info -->
        <Element xsi:type="MyType">
          <Enabled>true</Enabled>
          <ID>1A619316-634A-43C0-BE69-97BB7865219F</ID>
          <Property1><xsl:value-of select="$parameter1"/></Property1>
          <Property2><xsl:value-of select="$parameter2" /></Property2>
          <Property3><xsl:value-of select="$parameter3" /></Property3>
          <Property4><xsl:value-of select="$parameter4" /></Property4>
          <Property5><xsl:value-of select="$parameter5" /></Property5>
        </Element>
      </outxsl:template>

      <!-- Output everything for all the Details -->
      <outxsl:template match="/Element/Details/Detail">
        <!-- Copy all attributes and nodes -->
        <outxsl:copy-of select="@* | node()"/>

        <Detail>
          <Property1>1A619316-634A-43C0-BE69-97BB7865219F</Property1>
          <Property2>aName</Property2>
          <Property3><xsl:value-of select="$parameter6"/></Proprty3>
          <Property4>anotherName</Property4>
        </Detail>
      </outxsl:template>
    </outxsl:stylesheet>      
  </xsl:template>
</xsl:stylesheet>

当我在VS 2013 XSLT工具中运行此转换时，它可以工作，我得到一个新的XSLT，如下所示：

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <xsl:output method="xml" indent="yes" />
  <xsl:template match="/Element/Elements/Element">
    <xsl:copy-of select="@* | node()" />
    <Element xsi:type="MyType">
      <Enabled>true</Enabled>
      <ID>1A619316-634A-43C0-BE69-97BB7865219F</ID>
      <Property1>value1</Property1>
      <Property2>value2</Property2>
      <Property3>value3</Property3>
      <Property4>value4</Property4>
      <Property5>value5</Property5>
    </Element>
  </xsl:template>
  <xsl:template match="/Element/Details/Detail">
    <xsl:copy-of select="@* | node()" />
    <Detail>
      <Property1>1A619316-634A-43C0-BE69-97BB7865219F</Property1>
      <Property2>aName</Property2>
      <Property3>Default6</Property3>
      <Property4>anotherName</Property4>
    </Detail>
  </xsl:template>
</xsl:stylesheet>

当我尝试运行第二个XSLT时，我得到了＆＃34;类型＆＃39;属性＆＃39;不能在类型为＆＃39; Root的节点内构建。＆＃39;＆＃34;错误。当我尝试启动VS2013 XSLT调试器时，VS崩溃，所以我甚至无法弄清楚错误发生在哪一行。我已尝试在那里评论大部分代码并且错误仍然发生，因此我认为错误位于顶部附近。

请有人帮我弄清楚第二个XSLT＆amp;如何修复第一个？

修改

以下是第二个XSLT要处理的XML示例：

答案 0 :(得分：1)

首先，请注意您的（第二个）XSLT生成的XML没有根元素 - 根本就没有XML。

现在，AFAICT有问题的部分在这里：

  <xsl:template match="/Element/Elements/Element">
    <xsl:copy-of select="@* | node()" />

您正在使用属性匹配元素，但您没有创建相应的输出元素。因此，无法执行复制@*的指令，因为没有元素可以＆＃34;携带＆＃34;复制的属性。
