XContainer.Nodes Method


依照文件順序,傳回這個項目或文件之子代節點的集合。Returns a collection of the child nodes of this element or document, in document order.

 System::Collections::Generic::IEnumerable<System::Xml::Linq::XNode ^> ^ Nodes();
public System.Collections.Generic.IEnumerable<System.Xml.Linq.XNode> Nodes ();
member this.Nodes : unit -> seq<System.Xml.Linq.XNode>
Public Function Nodes () As IEnumerable(Of XNode)
Public Iterator Function Nodes () As IEnumerable(Of XNode)



IEnumerable<T>XNode,包含此 XContainer 的內容 (根據文件順序)。An IEnumerable<T> of XNode containing the contents of this XContainer, in document order.


下列範例會建立具有各種類型節點的 XML 樹狀結構。The following example creates an XML tree with a variety of types of nodes. 然後,它會查詢此 axis 方法來列舉和列印節點。It then queries this axis method to enumerate and print the nodes.

XElement xmlTree = new XElement("Root",  
    new XElement("Child1", 1),  
    new XElement("Child2", 2),  
    new XComment("a comment"),  
    new XElement("Child3", 3),  
    new XElement("Child4", 4),  
    new XText("mixed content"),  
    new XElement("Child5", 5)  
IEnumerable<XNode> nodes =  
    from nd in xmlTree.Nodes()  
    select nd;  
foreach (XNode node in nodes)  
Dim xmlTree As XElement = _   
            <!--a comment-->  
            <Child4>4</Child4>mixed content<Child5>5</Child5>  
Dim nodes = From nd In xmlTree.Nodes() _  
            Select nd  
For Each node In nodes  

這個範例會產生下列輸出:This example produces the following output:

<!--a comment-->  
mixed content  

下列範例會建立 XML 樹狀結構,其中包含各種類型的節點。The following example creates an XML tree that contains a variety of types of nodes. 接著,它會列舉樹狀結構的各個部分,並列印節點類型。It then enumerates through portions of the tree, printing the node types.

XDocument xmlTree = new XDocument(  
    new XComment("a comment"),  
    new XProcessingInstruction("xml-stylesheet", "type=\"text/xsl\" href=\"hello.xsl\""),  
    new XElement("Root",  
        new XAttribute("Att", "attContent"),  
        new XElement("Child1",  
            new XCData("CDATA content")  
        new XElement("Child2",  
            new XText("Text content")  
foreach (XNode node in xmlTree.Nodes())  
    if (node.NodeType == XmlNodeType.Element)  
        foreach (XAttribute att in ((XElement)node).Attributes())  
        foreach (XNode node2 in ((XElement)node).Nodes())  
            if (node2.NodeType == XmlNodeType.Element)  
                foreach (XNode node3 in ((XElement)node2).Nodes())  
Dim xmlTree As XDocument = _   
    <?xml version="1.0" encoding="utf-8"?>  
    <!--a comment-->  
    <?xml-stylesheet type='text/xsl' href='hello.xsl'?>  
    <Root Att="attContent">  
        <Child1><![CDATA[CDATA content]


請注意,內容不包含屬性。Note that the content does not include attributes. LINQ to XMLLINQ to XML中,屬性不會被視為樹狀結構的節點。In LINQ to XMLLINQ to XML, attributes are not considered to be nodes of the tree. 它們是與專案相關聯的名稱/值配對。They are name/value pairs associated with an element.

這個方法會使用延後的執行。This method uses deferred execution.
