PowerShell从XML属性编辑#text

Question

问题如下：

$xml = [xml](Get-Content $USSExternalContentTypeFile)   
$xml.Model.Properties.Property. ....
$xml.Save($USSExternalContentTypeFile)   

名称类型#text
---- ---- -----
Connect Integrated Security System.String textxtxtxtxtxtxtxt

<Property Name="Connect Integrated Security" Type="System.String">SSPI</Property>

帮助多个xml属性替换#text？

完成：     属性[2]。'＃text'='foo'

Answer 1

尝试这种方式来访问#text属性：

PS> $xml = [xml]'<Property Name="Connect Integrated Security" Type="System.String">SSPI</Property> '
PS> $xml.Property

Name                                    Type                                    #text
----                                    ----                                    -----
Connect Integrated Security             System.String                           SSPI

PS> $xml.Property.'#text' = 'foo'

PS> $xml.Property

Name                                    Type                                    #text
----                                    ----                                    -----
Connect Integrated Security             System.String                           foo

作为PowerShell的XML节点自动NoteProperties的替代方法，您还可以使用XPath来获取所需的节点。假设您希望所有属性节点的名称属性为“Connect Integrated Security”，您可以使用：

$nodes = $xml.SelectNodes("//Property[@Name='Connect Integrated Security']")
$nodes | % {
    $_."#text" = "SomeNewValue" # Changes SSPI to this.
}

如果你想坚持使用NoteProperties，这可能会有效：

$xml.Model.Properties.Property | % {
    $_."#text" = "SomeNewValue" # Changes SSPI to this.
}
