需要使用PowerShell解析xml的帮助吗

XML不是我的专长，我正在尝试使用PowerShell 4.0解析XML文件。我试图解析的XML文件post_XML_question.XML如下所示：

<?xml version="1.0" encoding="utf-8"?>
<cluster_vips>
  <svip cluster_nme="LabCluster1">
    <node node_nme="Lab1Node1" env_cde="LAB" cluster_node_nbr="1" server_dsc="Lab Cluster Node 1" />
    <node node_nme="Lab1Node2" env_cde="LAB" cluster_node_nbr="2" server_dsc="Lab Cluster Node 2" />
    <node node_nme="Lab1Node3" env_cde="LAB" cluster_node_nbr="3" server_dsc="Lab Cluster Node 3" />
  </svip>
  <svip cluster_nme="LabCluster2">
    <node node_nme="Lab2Node1" env_cde="LAB" cluster_node_nbr="1" server_dsc="Lab VM Cluster Node 1" />
    <node node_nme="Lab2Node2" env_cde="LAB" cluster_node_nbr="2" server_dsc="Lab VM Cluster Node 2" />
  </svip>
  <svip cluster_nme="LabCluster3">
    <node node_nme="Lab3Node1" env_cde="LAB" cluster_node_nbr="1" server_dsc="Lab Cluster Node 1" />
    <node node_nme="Lab3Node2" env_cde="LAB" cluster_node_nbr="2" server_dsc="Lab Cluster Node 2" />
    <node node_nme="Lab3Node3" env_cde="LAB" cluster_node_nbr="3" server_dsc="Lab Cluster Node 3" />
  </svip>
  <svip cluster_nme="DevTestCluster">
    <node node_nme="DevTestNode1" env_cde="MIX" cluster_node_nbr="1" server_dsc="Development/Test cluster Node 1" />
    <node node_nme="DevTestNode2" env_cde="MIX" cluster_node_nbr="2" server_dsc="Development/Test cluster Node 2" />
    <node node_nme="DevTestNode3" env_cde="MIX" cluster_node_nbr="3" server_dsc="Development/Test cluster Node 3" />
  </svip>
  <svip cluster_nme="ProdCluster">
    <node node_nme="ProdNode1" env_cde="PRO" cluster_node_nbr="1" server_dsc="Production cluster Node 1" />
    <node node_nme="ProdNode2" env_cde="PRO" cluster_node_nbr="2" server_dsc="Production cluster Node 2" />
    <node node_nme="ProdNode3" env_cde="PRO" cluster_node_nbr="3" server_dsc="Production cluster Node 3" />
  </svip>
</cluster_vips>

以下是迄今为止脚本的示例输出：

cluster_nme = LabCluster1
    node_nme          = Lab1Node1
    env_cde           = LAB
    cluster_node_nbr  = 1
    server_dsc        = Lab Cluster Node 1
cluster_nme = LabCluster2
    node_nme          = Lab2Node1
    env_cde           = LAB
    cluster_node_nbr  = 1
    server_dsc        = Lab VM Cluster Node 1
cluster_nme = LabCluster3
    node_nme          = Lab3Node1
    env_cde           = LAB
    cluster_node_nbr  = 1
    server_dsc        = Lab Cluster Node 1
cluster_nme = DevTestCluster
    node_nme          = DevTestNode1
    env_cde           = MIX
    cluster_node_nbr  = 1
    server_dsc        = Development/Test cluster Node 1
cluster_nme = ProdCluster
    node_nme          = ProdNode1
    env_cde           = PRO
    cluster_node_nbr  = 1
    server_dsc        = Production cluster Node 1

它只返回每个集群的第一个节点。有人能帮我返回丢失的节点条目吗

感谢您的帮助。提前感谢。

您将获得一个节点，因为您编写了以下内容：

$XMLNode = $svip.selectSingleNode("node")

因此，根据您的需要，将

selectSingleNode

替换为

foreach

循环

selectNodes

：

foreach ($svip in $nodelist)
{
    $cluster_nme = $svip.getAttribute("cluster_nme")

    foreach ($XMLNode in $svip.selectNodes("node"))
    {
        $node_nme         = $XMLNode.node_nme
        $env_cde          = $XMLNode.env_cde
        $cluster_node_nbr = $XMLNode.cluster_node_nbr
        $server_dsc       = $XMLNode.server_dsc

        write-output "cluster_nme = $cluster_nme"
        write-output "    node_nme          = $node_nme"
        write-output "    env_cde           = $env_cde"
        write-output "    cluster_node_nbr  = $cluster_node_nbr"
        write-output "    server_dsc        = $server_dsc"
    }
}

哦，它像个冠军。停止用头撞墙感觉很好。

foreach ($svip in $nodelist)
{
    $cluster_nme = $svip.getAttribute("cluster_nme")

    foreach ($XMLNode in $svip.selectNodes("node"))
    {
        $node_nme         = $XMLNode.node_nme
        $env_cde          = $XMLNode.env_cde
        $cluster_node_nbr = $XMLNode.cluster_node_nbr
        $server_dsc       = $XMLNode.server_dsc

        write-output "cluster_nme = $cluster_nme"
        write-output "    node_nme          = $node_nme"
        write-output "    env_cde           = $env_cde"
        write-output "    cluster_node_nbr  = $cluster_node_nbr"
        write-output "    server_dsc        = $server_dsc"
    }
}
