如何使用Powershell修改XML文件

Question

嗨朋友们我想将<Option Name="Activate">1</Option>中的某些文字值修改为<Option Name="Activate">0</Option>。我无法使用PowerShell找到节点值<Option Name="Activate">1</Option>。下面是我想要修改文本的完整代码部分。请帮忙。

<User Name="Richard">
        <Option Name="Pass">b56e0b4ea4962283bee762525c2d490f</Option>
        <Option Name="Containers">MasterVal</Option>
        <Option Name="Max Limit Allowed">2</Option>
        <Option Name="Limit Allowed">0</Option>
        <Option Name="User Limit">0</Option>
        <Option Name="Activate">1</Option>
        <Option Name="Feedback"></Option>
        <Option Name="ForceSsl">2</Option>
        <FileAllowed>
            <Disallowed />
            <Allowed />
        </FileAllowed>
        <Authorizations />
        <SpeedLimits DlType="0" DlLimit="10" ServerDlLimitBypass="2" UlType="0" UlLimit="10" ServerUlLimitBypass="2">
            <Download />
            <Upload />
        </SpeedLimits>
    </User>

Download XML File Here

到目前为止，我已经尝试了以下代码，但无法完成。 ：（

$xml = New-Object XML
$XML.Load("D:\PSScript\BookStore.xml")
$xml.bookstore.Users.user |
Where-Object { ($_.Name -eq 'Richard')} |
Select-Object -Property Option

**注意：我想在这里使用一个条件，例如我想仅为特定用户更改1 Tag文本值，简而言之，我想根据用户ID修改文本，比如name = Richard更改其{{ 1}}到<Option Name="Activate">1</Option> **

Answer 1

您的主要问题是您需要将选项元素视为数组。我将你的xml片段复制到一个名为test.xml的文件中，这个代码可以工作（我将解释我是如何在每一步中解析xml文件以显示Option作为数组显示的位置）：

[xml] $info = Get-Content test.xml #Shorthand for New-Object..Load
#This command isn't necessary but is helpful when looking for an attribute
$info | Format-List *

#From above command saw that $info.User is the base document element
$info.User
#showed Attribute in Option
$info.User.Option
#displayed an array element with Attribute as the 5 (6th cause you start at 0) index
$info.User.Option[5]
#displayed Name and #text attributes with #text = 1
$info.User.Option[5].'#text' = "0"
#updated #text attribute to 0

通过这种方式，您应该能够修改脚本以使用完整的xml文件。

由于您仍有问题，更好的解决方案是调整您的xml，以便您可以作为完整对象访问每个用户，而不是通过属性进行解析：

     <User>
         <name>Richard</name>
         <pass>b56e0b4ea4962283bee762525c2d490f</pass>
         <containers>MasterVal</containers>
         <maxLimit>2</maxLimit>
         <minLimit>0</minLimit>
         <userLimit>0</userLimit>
         <activate>1</activate>
         <feedback></feedback>
         <forceSsl>2</forceSsl>
         <FileAllowed>
             <Disallowed />
             <Allowed />
         </FileAllowed>
         <Authorizations />
         <SpeedLimits DlType="0" DlLimit="10" ServerDlLimitBypass="2" UlType="0"
     UlLimit="10" ServerUlLimitBypass="2">
             <Download />
             <Upload />
         </SpeedLimits>
     </User>

然后，您可以$info.User.Richard访问每个用户，并使用$info.User.Richard.activate = 0更改每个激活标记。如果你不能这样做，你需要使用foreach：

[xml] $info = Get-Content test.xml
foreach ($i in $info.BookStore.Users.User) {
    if ($i.Name -eq "Richard") {
        foreach ($e in $i.Option) {
            if ($e.Name -eq "Activate") {
                $e.'#text' = "0"
            }
        }
    }
}

然后将xml写回文件。注意：如果您想稍后简化，请查看select和select-xml的使用
