Question

XML问题让我感到难过，但可能非常简单......

XML就像：

    <header>
    <createdOn>16 Sep 2009</createdOn>
    <createdBy>Jez</createdBy>
</header>
<agents>
    <agent>
            <agentDetails>
                    <agentName>text</agentName>
                    <agentTelephone>text</agentTelephone>
            </agentDetails>
            <properties>
                    <property>
                            <propertyid>number</propertyid>
                            <address>
                                    <number>1</number>

                            </address>

                                    <briefDescription>text</briefDescription>
                                    <addDescription>long-text</addDescription>
                                    <floorSize>
                                            <size>80</size>

                                            <bullet>No Of Bedrooms : 2</bullet>
                                            <bullet>Condition : Habitable</bullet>
                                            <bullet>Land Size (M2): 2,000</bullet>
                                    </bullets>
                            </description>
                            <images>
                                    <image>
                                            <thumbnail>URL</thumbnail>
                                            <image>URL</image>
                                            <alttext></alttext>
                                    </image>
                                    <image>
                                            <thumbnail>URL</thumbnail>
                                            <image>URL</image>
                                            <alttext></alttext>
                                    </image>
                            </images>
                            <links>
                                    <link>
                                            <type>text</type>
                                            <url>url</url>
                                    </link>
                                    <link>
                                            <type>text</type>
                                            <url>url</url>
                                    </link>
                            </links>
                    </property>
            </properties>
    </agent>
 </agents>

我想使用的代码是：

    Set NodeList = objXML.documentElement.selectNodes("agents/agent/properties/property")
For Each Node In NodeList
    'I want to be able to extract distinct fields here...
    response.write Node.selectSingleNode("address/street") & "<br/>"
    response.write Node.selectSingleNode("description/briefDescription") & "<br/>"
Next

但是，我不知道如何。

另外，这可能是一个问题，例如<images>和<links>标签。

建议吗？

我正在使用的代码是：

Set NodeList = objXML.documentElement.selectNodes("agents/agent/properties/property")
For Each Node In NodeList
    Set AddrNode = Node.selectSingleNode("address/street/text()")
    if not AddrNode Is Nothing then response.write AddrNode.nodeValue & "<br/>"
    set AddrNode = nothing

    Set AddrNode = Node.selectSingleNode("address/region/text()")
    if not AddrNode Is Nothing then response.write AddrNode.nodeValue & "<br/>"
    set AddrNode = nothing

    For Each ImgNode In Node.selectNodes("images/image")
        Set ThNode = ImgNode.selectSingleNode("thumbnail/text()")
        if not ThNode Is Nothing then response.write ThNode.nodeValue & "<br/>"
        set ThNode = nothing
        Set ThNode = ImgNode.selectSingleNode("image/text()")
        if not ThNode Is Nothing then response.write ThNode.nodeValue & "<br/>"
        set ThNode = nothing
        Set ThNode = ImgNode.selectSingleNode("alttext/text()")
        if not ThNode Is Nothing then response.write ThNode.nodeValue & "<br/>"
        set ThNode = nothing
    next
Next

我希望其他人发现它有用！

首先，您发布的XML示例无效。它缺少根元素（或具有多个根元素，具体取决于您的观点）。此外，<sleeps>元素永远不会关闭。我认为这些可能是你的例子中的拼写错误？

我不确定你的意思是“我希望能在这里提取不同的字段。”您能举例说明您的输出吗？

如果没有更多信息，我建议尝试一些变体：

Dim NodeList, Node, SubNode
'' # Note: Replace [root] with your actual root level element
Set NodeList = objXML.documentElement.selectNodes("/[root]/agents/agent/properties/property")
For Each Node In NodeList
    '' # Do something useful... ?? Distinct fields??
    Set Node = Node.selectSingleNode("address/street/text()")
    If Not Node Is Nothing Then
        Response.Write Server.HTMLEncode(Node.nodeValue) & "<br />"
    End If
Next

这有帮助吗？

使用Classic ASP的XML selectNodes
