Question

我有以下课程：

public class HelloWorldDictionary
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public Dictionary<string, string> Items { get; set; }
}

和XSLT一样：

<xsl:template match="/HelloWorldDictionary">
  <html xmlns="http://www.w3.org/1999/xhtml">
  <br/>
  <a>
    Hi there <xsl:value-of select="FirstName" /> <xsl:value-of select="LastName" />!
  </a>
  <br/>
  <br/>
  <xsl:for-each select="Items/*">
    <xsl:value-of select="Key?" />
    <span> : </span>
    <xsl:value-of select="Value?" />
    <br/>
  </xsl:for-each>
</html>

正如您所料，上述for-each将无效......

生成的XML如下：

<HelloWorldDictionary xmlns="http://schemas.datacontract.org/2004/07/CommunicationTests.XsltEmail" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<FirstName>Foo</FirstName>
<Items xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
    <a:KeyValueOfstringstring>
        <a:Key>Key1</a:Key>
        <a:Value>12345678912</a:Value>
    </a:KeyValueOfstringstring>
    <a:KeyValueOfstringstring>
        <a:Key>Key2</a:Key>
        <a:Value>ABC1234</a:Value>
    </a:KeyValueOfstringstring>
    <a:KeyValueOfstringstring>
        <a:Key>Key3</a:Key>
        <a:Value>Test</a:Value>
    </a:KeyValueOfstringstring>
</Items>
<LastName>Bar</LastName>

从Items词典中获取每个键值对的正确XSLT语法是什么？

问题中的xml，命名空间是尴尬的一点;你需要在整个过程中观察命名空间。我们假设你有：

xmlns:dc="http://schemas.datacontract.org/2004/07/CommunicationTests.XsltEmail"
xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/Arrays"

位于xslt的顶部;然后我们有（未经测试的）类似的东西：

<xsl:template match="/dc:HelloWorldDictionary">
  <html xmlns="http://www.w3.org/1999/xhtml">
  <br/>
  <a>
    Hi there <xsl:value-of select="dc:FirstName" /> <xsl:value-of select="dc:LastName" />!
  </a>
  <br/>
  <br/>
  <xsl:for-each select="dc:Items/*">
    <xsl:value-of select="a:Key" />
    <span> : </span>
    <xsl:value-of select="a:Value" />
    <br/>
  </xsl:for-each>
</html>

然而，在大多数情况下，IMO最好坚持使用默认（空）命名空间;遗憾的是，DataContractSerializer不同意......
