Linq to XML（我无法访问标签之间的值）

发布于 2024-08-10 05:00:37 字数 1022 浏览 3 评论 0原文

我需要使用 linq to Xml 访问地址标记下的值。

<p1:Person>
  <p2:ID>1</p2:ID>
  <p2:Name>Qwerty</p2:Name>
  <p2:Address>
    <p2:street>1111 abc</p2:street>
    <p2:road # >9</p2:road #>
  </p2:Address>
<p1:Person>

我写了一个这样的查询

ArrayList nodes = new ArrayList();
List<XElement> personNode = xml.Elements().Where(e => e.Name.LocalName == "Person").ToList();
foreach (XElement x in personNode )
{
    IEnumerable<XElement> addressNode = x.Elements().Where(e => e.Name.LocalName == "Address");
    foreach (XElement x in addressNode)
    {                
        IEnumerable<XElement> streetNode= x.Elements().Where(e => e.Name.LocalName == "street");
        foreach (XElement x1 in streetNode)
        {
            Nodes.Add(x1.Value);
        }
    }
}

这应该给我节点数组列表中的街道值..但是错误接近“addressNode”..没有值进入addressNode变量。

请对此查询提出一些输入。那会有很大的帮助。

问候， Linq新手

I need to access Values under Address Tag using linq to Xml.

<p1:Person>
  <p2:ID>1</p2:ID>
  <p2:Name>Qwerty</p2:Name>
  <p2:Address>
    <p2:street>1111 abc</p2:street>
    <p2:road # >9</p2:road #>
  </p2:Address>
<p1:Person>

I wrote a query like this

ArrayList nodes = new ArrayList();
List<XElement> personNode = xml.Elements().Where(e => e.Name.LocalName == "Person").ToList();
foreach (XElement x in personNode )
{
    IEnumerable<XElement> addressNode = x.Elements().Where(e => e.Name.LocalName == "Address");
    foreach (XElement x in addressNode)
    {                
        IEnumerable<XElement> streetNode= x.Elements().Where(e => e.Name.LocalName == "street");
        foreach (XElement x1 in streetNode)
        {
            Nodes.Add(x1.Value);
        }
    }
}

This should give me the Street Value in Nodes Arraylist.. But Error is near "addressNode".. No values are getting into addressNode variable.

Please Throw some input on this Query. That would be of great Help.

看起来您正在尝试在嵌套的 foreach 循环中重新使用 x 变量。这有效吗？

ArrayList nodes = new ArrayList();
List<XElement> personNode = xml.Elements().Where(e => e.Name.LocalName == "Person").ToList();
foreach (XElement p in personNode )
{
    IEnumerable<XElement> addressNode = p.Elements().Where(e => e.Name.LocalName == "Address");
    foreach (XElement a in addressNode)
    {                
        IEnumerable<XElement> streetNode= a.Elements().Where(e => e.Name.LocalName == "street");
        foreach (XElement s in streetNode)
        {
            Nodes.Add(s.Value);
        }
    }
}

Looks like you're trying to re-use the x variable inside the nested foreach loop. Does this work?

ArrayList nodes = new ArrayList();
List<XElement> personNode = xml.Elements().Where(e => e.Name.LocalName == "Person").ToList();
foreach (XElement p in personNode )
{
    IEnumerable<XElement> addressNode = p.Elements().Where(e => e.Name.LocalName == "Address");
    foreach (XElement a in addressNode)
    {                
        IEnumerable<XElement> streetNode= a.Elements().Where(e => e.Name.LocalName == "street");
        foreach (XElement s in streetNode)
        {
            Nodes.Add(s.Value);
        }
    }
}
