類型參數

參數

傳回

IEnumerable<T> XNode來源集合中每個文件與元素的子節點之一。

範例

以下範例檢索了名為 的 Child元素集合中每個節點的所有子節點。

XElement xmlTree = XElement.Parse(
    @"<Root><Child>aaa<GrandChild>Text</GrandChild>bbb</Child>" +
    @"<Child>ccc<GrandChild>Text</GrandChild>ddd</Child></Root>");
IEnumerable<XNode> nodes = xmlTree.Elements("Child").Nodes();

foreach (XNode node in nodes)
{
    switch (node.NodeType)
    {
        case XmlNodeType.Element:
            Console.WriteLine("Element: {0}", ((XElement)node).Name);
            break;
        case XmlNodeType.Text:
            Console.WriteLine("Text: {0}", ((XText)node).Value);
            break;
    }
}

Dim xmlTree As XElement = _
    <Root>
        <Child>aaa<GrandChild>Text</GrandChild>bbb</Child>
        <Child>ccc<GrandChild>Text</GrandChild>ddd</Child>
    </Root>

Dim nodes = xmlTree.<Child>.Nodes()

' Note that XNode uses XmlNodeType, which is in the System.Xml namespace.
For Each node As XNode In nodes
    Select Case node.NodeType
        Case XmlNodeType.Element
            Console.WriteLine("Element: {0}", DirectCast(node, XElement).Name)
        Case XmlNodeType.Text
            Console.WriteLine("Text: {0}", DirectCast(node, XText).Value)
    End Select
Next

此範例會產生下列輸出：

Text: aaa
Element: GrandChild
Text: bbb
Text: ccc
Element: GrandChild
Text: ddd
