Question

这是我的XSL转换文件：

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:Message="http://schemas.microsoft.com/dynamics/2011/01/documents/Message"
xmlns:BankPositivePay="http://schemas.microsoft.com/dynamics/2008/01/documents/BankPositivePay">
  <xsl:output method="xml" indent="yes" encoding="utf-8" omit-xml-declaration="no"/>
  <xsl:template match="/">
    <Header>
      <records>
        <record>
          <xsl:value-of select="/BankPositivePay/BankAccountTable/AccountNum"/>
        </record>
      </records>
    </Header>
  </xsl:template>
</xsl:stylesheet>

输入的xml文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<Envelope xmlns="http://schemas.microsoft.com/dynamics/2011/01/documents/Message">

问题是我得到的输出为：

<?xml version="1.0" encoding="utf-8"?>
<Header xmlns:Message="http://schemas.microsoft.com/dynamics/2011/01/documents/Message" xmlns:BankPositivePay="http://schemas.microsoft.com/dynamics/2008/01/documents/BankPositivePay">
  <records>
    <record></record>
  </records>
</Header>

记录元素为空，但它应该返回AccountNum 34567.任何帮助都表示赞赏。谢谢。

Answer 1

您的选择表达式有两个问题：

您没有在路径中使用命名空间。
您没有找到所需的节点

命名空间问题经常出现在这里。针对具有非空名称空间URI 的节点的XPath选择器的每一步都必须加上前缀（如果您使用名称选择器将其作为目标）。

如果更改表达式

<xsl:value-of select="/BankPositivePay/BankAccountTable/AccountNum"/>

到

<xsl:value-of select="//BankPositivePay:BankPositivePay/BankPositivePay:BankAccountTable/BankPositivePay:AccountNum"/>

然后你的输出将是

<Header xmlns:Message="http://schemas.microsoft.com/dynamics/2011/01/documents/Message" xmlns:BankPositivePay="http://schemas.microsoft.com/dynamics/2008/01/documents/BankPositivePay">
    <records>
        <record>34567</record>
    </records>
</Header>

需要//，因为您定位的元素不在根目录中。 //通常被避免，因为它“昂贵”;你如何准确定位该节点取决于你的要求。
