该程序不起作用。它开始但有错误，没有读取两个xml文件？

文件MIK_Autokontinent.xml的示例

<?xml version="1.0" encoding="utf-8"?><FieldConditions Enable="0" Version="1"/><FieldCostOptions Enabled="1" Version="1"><IncreaseCost Enabled="1" Percent="-5"/></FieldCostOptions>

Answer 1

在函数顶部添加一个param块，声明两条路径：

function chpecent {
param(
  [string]$Path1,
  [string]$Path2
)
...
}

，然后将所有硬编码路径替换为那些

    $form1_Load = {
        $inputpecentw1.Text = [xml](Get-Content $Path1) | ForEach-Object { $_.SelectNodes(' //FieldCostOptions/IncreaseCost') | ForEach-Object { $_.GetAttribute("Percent") } } | Out-String
        $inputpecentw2.Text = [xml](Get-Content $Path2) | ForEach-Object { $_.SelectNodes(' //FieldCostOptions/IncreaseCost') | ForEach-Object { $_.GetAttribute("Percent") } } | Out-String
    }

...等等，然后最终调用如下函数：

PS C:\> chpercent -Path1 c:\program\MIK_Autokontinent.xml -Path2 c:\program\MIK_AutoPremium.xml

该程序不起作用。它开始但有错误，没有读取两个xml文件？
