PowerShell 不允许我将 XML 节点添加到 XML 文件（使用 PowerShell 5.1.183）

Question

从我试图将 XML 节点附加到父 XML 元素的一周开始，我就一直坚持这一点。子节点和父节点如下所示：

[xml]$childxml = @"
<ClaimsProvider>
    <Bomain> hey there</Bomain>
    <Name>Login using </Name>
    <TechnicalProfiles>
        <TechnicalProfile Id="MIDC-What">
            <DisplayName> Employee</DisplayName>
            <Description>Login with your account</Description>
            <Protocol Name="OpenIdConnect" />
            <Metadata>
                <Item Key="METADATA">https://login.microsoftonline.com</Item>
                <Item Key="client_id">Mangal</Item>
                <Item Key="ValidTokenIssuerPrefixes">https://login.microsoftonline.com</Item>
            </Metadata>
            <Cryptograph>
                <Key Id="client_secret" StorageReferenceId="key" />
            </Cryptograph>
            <IncludeTechnicalProfile ReferenceId="MIDC-Shared" />
        </TechnicalProfile>
    </TechnicalProfiles>
</ClaimsProvider>
"@

我想将这个子节点添加到这个文件（文件名：permissions.xml）

<TrustFrameworkPolicy xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"">
  <BasePolicy>
  </BasePolicy>
  <BuildingBlocks></BuildingBlocks>

            <DisplayName> Employee</DisplayName>

    <ClaimsProvider>

        </TechnicalProfile>

我现在正在做这个：

将文档保存在变量中

$doc = [xml](Get-Content permissions.xml)

将子变量附加到 $doc xml

[Void]$doc.TrustFrameworkPolicy.ClaimsProviders.AppendChild($childxml)

我收到以下错误：

Exception calling "AppendChild" with "1" argument(s): "The specified node cannot be inserted as the valid child of this node, because the specified node is the wrong type."

Answer 1

您不能附加来自不同 XML 文档的 XmlNode。相反，您必须从要附加到的文档中创建一个节点：

$childxml = $doc.CreateDocumentFragment()
$childxml.InnerXml = @'
<ClaimsProvider>
    <Bomain> hey there</Bomain>
    <Name>Login using </Name>
    <TechnicalProfiles>
        <TechnicalProfile Id="MIDC-What">
            <DisplayName> Employee</DisplayName>
            <Description>Login with your account</Description>
            <Protocol Name="OpenIdConnect" />
            <Metadata>
                <Item Key="METADATA">https://login.microsoftonline.com</Item>
                <Item Key="client_id">Mangal</Item>
                <Item Key="ValidTokenIssuerPrefixes">https://login.microsoftonline.com</Item>
            </Metadata>
            <Cryptograph>
                <Key Id="client_secret" StorageReferenceId="key" />
            </Cryptograph>
            <IncludeTechnicalProfile ReferenceId="MIDC-Shared" />
        </TechnicalProfile>
    </TechnicalProfiles>
</ClaimsProvider>
'@

[Void]$doc.TrustFrameworkPolicy.ClaimsProviders.AppendChild($childxml)
