xml - 我的Powershell脚本输出的字符奇怪(编码错误)

Question

我编写了一个脚本来读取XML文件，并在某些特定的节点上进行一些编辑，然后将文件写回。

我遇到的问题是输出文件中有一些额外的字符添加到了我未编辑的节点上。

我假设这是一个编码问题。

我脚本中的相关代码是

function getAssigneeID ($assigneeName) {
    #param($assigneeName)
    #write($assigneeName)
    $assigneeID = $nameIDHash[$assigneeName]
    if ($assigneeID -eq $null -or $a -eq "") {
        return 'Not Found'
    } else {
        return $assigneeID
    }
}
function ValidateAssigneeField ($assignee, $fileContent, $fileURI, $assignees) {
    If (($assignee.InnerText.Length -le 2) -or ($assignee.InnerText.Length -ne 6) -or ($assignee.InnerText[1] -ne 'Z')) {
        write("`tAssignee " + $assignee.InnerText + " is invalid.") >> $Output_Log_File
        #find assignee's ID in nameIDHash 
        $assigneeID = getAssigneeID -assigneeName $assignee.InnerText
        if ($assigneeID -eq 'Not Found' -or $assigneeID -eq $null){
            write("`t`tThe ID for the invalid user " + $assignee.InnerText + " is Not Found.") >> $Output_Log_File
        } else {
            #if the assigneeID is in the list of assignees, remove the name, otherwise replace the name with the ID and save the file.
            write("`t`tThe ID for the invalid user " + $assignee.InnerText + " is " + $assigneeID) >> $Output_Log_File
            $assigneeIdAlreadyInList = $false
            foreach ($user in $assignees){
                #write("user = " + $user.InnerText + ", ID = " + $assigneeID)
                If ($user.InnerText -eq $assigneeID){
                    $assigneeIdAlreadyInList = $true
                } else {
                }
            }
            #write ($assigneeIdAlreadyInList)
            if ($assigneeIdAlreadyInList){
                write("`t`t" + $assigneeID + " already exists in the assignee list, removing " + $assignee.InnerText) >> $Output_Log_File
                [void]$assignee.ParentNode.RemoveChild($assignee)
            } else {
                write("`t`tReplacing " + $assignee.InnerText + " with " + $assigneeID + ".") >> $Output_Log_File
                $assignee.InnerText = $assigneeID
            }
            write("`t`tSaving the file " + $fileURI + ".") >> $Output_Log_File
            #$fileContent.save($fileURI)
            #$file | out-file -Encoding "UTF8" -FilePath $fileURI
            #$MyXML | out-file -Encoding "UTF8" -FilePath $fileURI
            #$fileContent | out-file -Encoding "UTF8" -FilePath $fileURI
        }
    } else {
        write("`tAssignee " + $assignee.InnerText + " is OK.") >> $Output_Log_File
    }
}
$workitemBasePath = "C:\temp\dev\workitems\Dev_ECH\"
$Output_Log_File = "C:\ALM\Reports\Dev_ECH - Correct All Assignees.txt"
$NameIDHash = @{
"Jade West" = "zzzzzz"
"Tonya Killebrew" = "AZCJNZ"}
$today = Get-Date -format s
write($today + " - Running Correct invalid Assignees.ps1.") > $Output_Log_File
$files = Get-ChildItem -Path $workitemBasePath -include workitem.xml -Recurse | % { $_.FullName }
foreach ($file in $files){
    write("Evaluating " + $file) >> $Output_Log_File
    [xml]$MyXML = Get-Content $file
    $assigneeList = $MyXML.SelectNodes('//work-item/field[@id="assignee"]/list/item')
    if ($assigneeList.count -eq 0) {
        $assigneeList  = $MyXML.SelectNodes('//work-item/field[@id="assignee"]')
    }
    foreach ($assignee in $assigneeList) {
        ValidateAssigneeField -assignee $assignee -fileContent $MyXML -fileURI $file -assignees $assigneeList
    }

}

然后在ValidateAssigneeField中，对受让人节点进行一些编辑，并使用

    $fileContent.save($fileURI)

在输出XML文件中，我看到以下额外的字符被添加到某些文本字段中。

  <field id="description" text-type="text/plain">​Navistar has reported that the transmission remains in Drive when the operator selects a fast sequence from Drive to Reverse to Manual mode. When selecting a similar sequence from Reverse to Drive to Manual mode, the transmission drive as expected.</field>

and和Â被添加在看似随机的位置。

我假设我需要找出原始XML的编码形式，然后以相同格式输出经过编辑的XML。

如何更改$ fileContent.save($ fileURI)命令的输出格式？

Answer 1

没有输入文件，请尝试以下更改:

[xml]$MyXML = Get-Content $file -Raw

编辑:
您也可以输出

$file | Out-File -Encoding "UTF8"

编辑编辑:

如果你这样做

$newfile = ValidateAssigneeField -assignee $assignee -fileContent $MyXML -fileURI $file -assignees $assigneeList 

$newfile | Out-File -Encoding "UTF8" -FilePath "DESTINATION"
