Question

我正在做一个使用XML文件的博客。我想用ListView显示所选Post的注释。这是我的XML文件：

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<NewDataSet>
<Toy>
<ID>1</ID>
<Type>Despicable Me</Type>
<Character>Agnes Gru</Character>
<Description>Agnes, like her sisters, wished to be adopted by someone who cared about her.
At first, Agnes is only one out of the three sisters to be excited to be adopted by Gru. 
 She happily hugs his leg and plays games with him, whereas her sisters are gawping at  
 Gru, their dream of the 'perfect parents' in tatters. 
She is unaware of Gru's own dislike of the whole adoption, her innocence prevailing. 
She is a very naive and innocent child, which is why Margo is so protective of her. 
She thinks Gru's dog is cute and chases after him, despite some protest from Margo.
  </Description>

 <Comments>
  <Comment>
    It's a very cute little girl!
  </Comment>
  <Comment>
    It's a very cute little girl!
  </Comment>
</Comments>
 </Toy>
</NewDataSet>

这是我的xsl文件：

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl">
<xsl:template match="NewDataSet">
<NewDataSet>
  <xsl:apply-templates/>
 </NewDataSet>
 </xsl:template>

<xsl:template match="Toy/Comments">
 <Toy>
  <Comments>
    <xsl:for-each select="*">
      <xsl:attribute name="{name()}">
        <xsl:value-of select="text()"/>
      </xsl:attribute>
    </xsl:for-each>
  </Comments>
 </Toy>
</xsl:template>
</xsl:stylesheet>

这是我的代码背后：（我成功通过了会议）

protected void Page_Load(object sender, EventArgs e)
{
String ID = Session["ID"].ToString(); 
XmlDataSource2.XPath = String.Format("/NewDataSet/Toy[@ID='{0}']/Comments",ID);
}

我认为我的代码背后有问题。有人可以帮助我吗？谢谢。

Answer 1

只是一个想法 - ID是一个元素，但在您的XPath中，您将其视为属性（@ID）。尝试将/NewDataSet/Toy[@ID='{0}']/Comments更改为/NewDataSet/Toy[ID='{0}']/Comments。

编辑：这是您转型的结果

正如你所看到的，你几乎失去了所有的标记。此外，ID元素已经消失，因此您的xpath无法返回任何数据 - 因为没有具有元素ID的Toy元素。

我不知道你想用xslt做什么 - 你应该详细说明。

但我不明白为什么你需要转换你的输入xml。 IMO应用于原始文档的xpath /NewDataSet/Toy[ID=1]/Comments/Comment应该可以完成工作。

在xml中选择所选节点的comments元素
