【问题描述】：

我正在尝试复制位于此处的示例 Click Here

但是，我无法达到预期的效果。 输出根本没有按需要生成。 我使用的输入：

<?xml version="1.0" encoding="UTF-8" ?>
<Order xmlns="http://www.book.org">
  <Bundle>
    <authors>
        <author>
            <authorId>100</authorId>

        </book>
        <book>
            <orderId>1111</orderId>
            <bookName>Hibernate In Action</bookName>
            <bookAuthorId>300</bookAuthorId>
        </book>
    </books>
</Bundle>
</Order>
**The Schema I have used in for my transformation**

<!-- begin snippet: js hide: false console: true babel: false -->

我用于转换的 XSLT：

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0"

      <books>
        <xsl:copy-of select="key('k', ns0:orderId)"/>

    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>
</xsl:stylesheet>

但是我得到的输出是：

<?xml version = '1.0' encoding = 'UTF-8'?>
<Order xmlns="http://www.book.org" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.book.org file:/C:/JDeveloper/mywork/SOADevelopment/XsltLearner/SOA/Schemas/BooksOrder.xsd">

            <bookAuthorId>100</bookAuthorId>
        </book>
         <book>
            <orderId>1111</orderId>
            <bookName>Hibernate In Action</bookName>

   <Bundle>

            <bookAuthorId>200</bookAuthorId>
        </book>
      </books>
   </Bundle>
</Order>

节点未填充。 我尝试使用 copy-of 查看第二个键的输出，但它什么也没打印。 你能否建议我哪里出错了。 知道我做错了什么吗？ 请帮忙 谢谢！

【参考方案1】：

据我了解您发布的文档示例，密钥的模式为<xsl:key name="a" match="ns0:Order/ns0:Bundle/ns0:authors/ns0:author" use="ns0:authorId"/>。我还将在任何使用 key 函数时删除 string 调用，例如使用<xsl:apply-templates select="key('a', key('k', ns0:orderId)/ns0:bookAuthorId )"/>。
