问题描述

大家好，

在Powershell脚本上需要帮助从一个文件复制XML节点并将其附加到另一个XML文件 。

目标：我们的xml文件具有相同的节点结构。但是，每次使用特定值更新来源时，&bbsp; b $ b &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; 必须手动将其更新为目标xml节点。我们会自动化这个，无论何时来源<
&NBSP; &NBSP; &NBSP; &NBSP; &NBSP;文件更新团队中的任何人都会让自动化人员了解它然后自动化人员将执行 &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;
此脚本用最新值更新目标xml节点。

当前情况： A 。成功：当前的Powershell脚本能够读取源xml节点，并且还能够&bbsp
&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;删除目标节点，然后使用源xml节点值附加目标xml。

&NBSP; &NBSP; &NBSP; &NBSP;的乙即可。
失败或错误：异常调用" ImportNode"用"2"表示"2"。参数："无法导入空节点。"

Hi ALL,

Need Help On Powershell Script For Copy XML Node From One File And Append It To Another XML File.

Objective : We have xml files with same node structure.However, everytime source is updated with certain value
it has to be updated manually into target xml node. We would to automate this one where whenever source
file is updated anyone from team will let the automation guy know about it and then automation guy will execute this script to update the target xml node with laest value.

Current Situation Is : A. Success : Current Powershell Script is able to read the source xml node and also able to
delete target node and then append the target xml with source xml node value.

B.Failure or Error : Exception calling "ImportNode" with "2" argument(s): "Cannot import a null node."
At E:\Carbon\xmlreplacenode-1.ps1:51 char:1
+ [void] $parent.AppendChild($servicefactoryconfig.ImportNode($newNode. ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : DotNetMethodException

Powershell Script :

XML Source&目标：节点名称是APILibaries，它是 < Section Name =" APILibraries" > < Item
