问题描述

我正在尝试从文本文件中提取一些数据。 这些是代码行：

param (
    [Parameter(mandatory=$true)]$XMLFile
)

Function New-WPFDialog() {
    Param([Parameter(Mandatory = $True,HelpMessage = 'XaML Data defining a GUI',Position = 1)]
        [string]$XamlData)

    # Add WPF and Windows Forms assemblies
    try { Add-Type -AssemblyName PresentationCore,PresentationFramework,WindowsBase,system.windows.forms }
    catch { Throw 'Failed to load Windows Presentation Framework assemblies.' }

    # Create an XML Object with the XaML data in it
    [xml]$xmlWPF = $XamlData

    # Create the XAML reader using a new XML node reader,UI is the only hard-coded object name here
    Set-Variable -Name XaMLReader -Value @{ 'UI' = ([Windows.Markup.XamlReader]::Load((new-object -TypeName System.Xml.XmlNodeReader -ArgumentList $xmlWPF))) }

    # Create hooks to each named object in the XAML reader
    $Elements = $xmlWPF.SelectNodes('//*[@Name]')
    ForEach ( $Element in $Elements ) {
        $VarName = $Element.Name
        $VarValue = $XaMLReader.UI.FindName($Element.Name)
        $XaMLReader.Add($VarName,$VarValue)
    }

    return $XaMLReader
}

Function Replace-InlineFormatting() {
    param([string]$InputString)
    $Temp = $InputString
    $Temp = $Temp.ToString().Replace("[","<")
    $Temp = $Temp.ToString().Replace("]",">")
    return $Temp
}

Function New-PopUpWindow() {
    param(
        [string]
        $Header = "No Header Supplied",$Body = "No Body Supplied")


    # This is the XaML that defines the GUI.
    $WPFXamL = @'
    <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

            <Button Name="OKButton" Content="OK" Width="75" Background="#FF0066CC" BorderBrush="White" Foreground="White" Padding="8,4" Margin="0,10"/>
        </StackPanel>
    </Window>
'@

    # Build Dialog
    $WPFGui = New-WPFDialog -XamlData $WPFXaml
    $WPFGui.Header.Text = $Header
    $WPFGui.Body.Text = Replace-InlineFormatting -Input $Body
    $WPFGui.OKButton.Add_Click( { $WPFGui.UI.Close() })
    $null = $WPFGUI.UI.dispatcher.InvokeAsync{ $WPFGui.UI.ShowDialog() }.Wait()
}

If(Test-Path -PathType Leaf $XMLfile) {
    [XML]$ScriptConfig = Get-Content $XMLfile

    $ScriptName = $ScriptConfig.Config.ScriptName
    $PopupHeader = $ScriptConfig.Config.Popup.Header
    $PopupBody = $ScriptConfig.Config.Popup.Body
    $CommandProgram = $ScriptConfig.Config.Command.Program
    $CommandArguments = $ScriptConfig.Config.Command.Arguments

    If($PopupHeader -and $PopupBody) { New-PopUpWindow -Header $PopupHeader -Body $PopupBody }
    If($CommandProgram) {
        If(Get-Command $CommandProgram -ErrorAction SilentlyContinue) {
            Invoke-Expression "$CommandProgram $CommandArguments"
        } Else {
            New-PopUpWindow -Header "ERROR" -Body "The command '$Command' cannot be found."
        }
    }
} Else {
    New-PopUpWindow -Header "ERROR" -Body "The XML file '$XMLfile' cannot be found."
}

我一直收到[]，所以没有结果。有人可以帮助我理解为什么吗？ 谢谢

解决方法

也许我误解了您的问题，但是从.txt收集数据确实非常容易。您可以使用3或4行代码打开和阅读文本文件：

f = open("file.txt","r+")
data = f.read()
print(data)
f.close()

，如果您要从.txt的特定行中查找数据，则可以使用：

f = open("file.txt","r+")
lines = f.readlines()
print(lines[25])
f.close()

或者如果您想在文本文件中一般查找特定数据

f = open("file.txt","r+")
read = f.read()
data = read
f.close()
if "<specific word you're looking for>" in data:
#react based on the information being in the data.

我不认为您必须弄乱.format或类似的东西，您可以只使用文件的路径，或者如果它与脚本位于同一文件夹中，则只需文件名即可。
