        $nodes = $XmlDocument.SelectNodes($XPath)
        $filteredNodes = @()
        
        foreach ($node in $nodes) {
            $match = $true
            foreach ($condition in $Conditions.GetEnumerator()) {
                $value = $node.SelectSingleNode($condition.Key).InnerText
                if ($value -ne $condition.Value) {
                    $match = $false
                    break
                }
            }
            
            if ($match) {
                $filteredNodes += $node
            }
        }

    # 导出数据为 XML
    function Export-ToXML {
        param(
            [object[]]$Data,
            [string]$RootNode,
            [string]$OutputFile
        )
        
        $xml = [xml]@"
    <?xml version="1.0" encoding="UTF-8"?>
    <$RootNode>
    </$RootNode>
    "@
        
        foreach ($item in $Data) {
            $node = $xml.CreateElement($item.GetType().Name)
            
            foreach ($prop in $item.PSObject.Properties) {
                $child = $xml.CreateElement($prop.Name)
                $child.InnerText = $prop.Value
                $node.AppendChild($child)
            }
            
            $xml.DocumentElement.AppendChild($node)
        }
        
        # 保存 XML 文件
        $xml.Save($OutputFile)
        Write-Host "已导出数据到：$OutputFile"
    }

这些技巧将帮助您更有效地处理 XML 数据。记住，在处理 XML 时，始终要注意数据的完整性和格式正确性。同时，建议在处理大型 XML 文件时使用流式处理方式，以提高性能。

PowerShell变量作用域深度解析

# 全局作用域示例
$Global:config = 'ServerConfig'

function Show-Config {
    # 局部作用域变量
    $localVar = 'LocalValue'
    Write-Host "全局变量: $Global:config"
    Write-Host "局部变量: $localVar"
}

Show-Config
Write-Host "外部访问: $localVar"  # 此处会报错

作用域修饰符对比

修饰符 可见范围 生命周期
Global 所有作用域 会话结束
Local 当前作用域 代码块结束
Script 脚本文件内 脚本执行结束
Private 当前作用域内部 代码块结束

最佳实践

  1. 避免过度使用全局变量
  2. 函数参数优先于外部变量引用
  3. 使用$script:访问脚本级变量
  4. 重要变量显式声明作用域

调试技巧

PowerShell 技能连载 - 批量检测服务器端口

使用 PowerShell 可以快速地检测服务器端口。以下是一个示例：

1
80, 443 | % { Test-Connection -ComputerName www.microsoft.com -TcpPort $_ }

在 PowerShell 提示符下运行这段代码，那么它将尝试连接到一个名为 www.microsoft.com 的计算机，并尝试连接端口 80 和 443。如果网络连接正常，那么您将会看到类似下面的输出：

PowerShell 技能连载 - JSON 数据处理技巧

在 PowerShell 中处理 JSON 数据变得越来越常见，特别是在与 Web API 交互或处理配置文件时。本文将介绍一些实用的 JSON 处理技巧。

首先，让我们看看如何创建和转换 JSON 数据：

# 创建 JSON 对象
$userData = @{
    name = "张三"
    age = 30
    hobbies = @("读书", "编程", "摄影")
    contact = @{
        email = "zhangsan@example.com"
        phone = "123-456-7890"
    }
}

# 转换为 JSON 字符串
$jsonString = $userData | ConvertTo-Json -Depth 10
Write-Host "JSON 字符串："
Write-Host $jsonString

# 从 JSON 字符串转换回对象
$object = $jsonString | ConvertFrom-Json
Write-Host "`n转换回对象："
$object | Format-List

处理复杂的 JSON 数据时，我们可以使用自定义对象：

# 创建自定义对象并转换为 JSON
$customObject = [PSCustomObject]@{
    id = 1
    title = "PowerShell 技巧"
    author = "李四"
    tags = @("PowerShell", "自动化", "脚本")
    metadata = @{
        created = Get-Date
        version = "1.0.0"
    }
}

# 转换为 JSON 并保存到文件
$customObject | ConvertTo-Json -Depth 10 | Set-Content "article.json"

# 从文件读取 JSON
$loadedData = Get-Content "article.json" | ConvertFrom-Json

# 处理 API 响应

    "data": {
        "users": [
            {
                "id": 1,
                "name": "王五",
                "role": "admin"
            },
            {
                "id": 2,
                "name": "赵六",
                "role": "user"
            }
        ],
        "total": 2
    }
}
'@

# 解析 JSON 并访问嵌套数据
$response = $apiResponse | ConvertFrom-Json
$adminUsers = $response.data.users | Where-Object { $_.role -eq "admin" }
Write-Host "管理员用户："
$adminUsers | Format-Table

# 使用流式处理大型 JSON 文件
$jsonStream = [System.IO.File]::OpenRead("large-data.json")
$reader = [System.IO.StreamReader]::new($jsonStream)
$jsonText = $reader.ReadToEnd()
$reader.Close()
$jsonStream.Close()

# 使用 System.Text.Json 进行高性能解析
Add-Type -AssemblyName System.Text.Json
$jsonDoc = [System.Text.Json.JsonDocument]::Parse($jsonText)

# 访问特定属性
$value = $jsonDoc.RootElement.GetProperty("specificField").GetString()

一些实用的 JSON 处理技巧：

  1. 使用 -Compress 参数创建紧凑的 JSON：

    1
    $data | ConvertTo-Json -Compress

  2. 处理日期时间格式：

    1
    2
    3
    $dateObject = @{
        timestamp = (Get-Date).ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ssZ")
    } | ConvertTo-Json

  3. 验证 JSON 格式：

    function Test-JsonFormat {
        param([string]$JsonString)
        try {
            $null = $JsonString | ConvertFrom-Json
            return $true
        }
        catch {
            return $false
        }
    }

这些技巧将帮助您更有效地处理 JSON 数据。记住，在处理敏感数据时，始终要注意数据安全性，并考虑使用适当的加密方法。
