Powershell xml抓取

# 假设有一个名为 data.xml 的文件，内容如下：
# <fruits>
#   <fruit name="apple" color="red"/>
#   <fruit name="banana" color="yellow"/>
# </fruits>

# 使用 Select-Xml 抓取所有水果的名称和颜色
$xml = Get-Content data.xml -Raw
$fruitNodes = Select-Xml -Content $xml -XPath "//fruit"

foreach ($fruitNode in $fruitNodes) {
    $fruitName = $fruitNode.Node.Attributes["name"].Value
    $fruitColor = $fruitNode.Node.Attributes["color"].Value
    Write-Output "Fruit: $fruitName, Color: $fruitColor"
}

# 确保文件路径正确
$xmlPath = "C:\path\to\your\data.xml"
if (-Not (Test-Path $xmlPath)) {
    Write-Error "File not found: $xmlPath"
    exit
}

# 确保有读取权限
try {
    $xml = Get-Content $xmlPath -Raw
} catch {
    Write-Error "Failed to read file: $_"
    exit
}

# 使用更简单的 XPath 表达式进行测试
$fruitNodes = Select-Xml -Content $xml -XPath "//fruit"
if ($fruitNodes.Count -eq 0) {
    Write-Warning "No fruit nodes found with the given XPath expression."
