Hi all

Below is the xml i am having in a .xml file

<pre><?xml version="1.0" encoding="UTF-8"?>
<data>
  <input>
    <common>
      <AOGatewayID></AOGatewayID>
      <SRNUM></SRNUM>
      <WONUM></WONUM>
      <INCNUM />
      <ResolverGroup></ResolverGroup>
      <ContactEmail></ContactEmail>
    </common>
    <params>:11/30/2016;:;:;:;:;:;:;:;:;:;:;:;:;:;:;:;:;:;:;:;:;:;:;:;:;RequestedFor:NEX9KUT</params>
  </input>
  <Processname></Processname>
  <retry-count></retry-count>
  <status></status>
  <Error_Desc></Error_Desc>
</data>

I need to delete the <params> tag and save the new xml in separate file

Please help me on this.

What I have tried:

[Xml]$xml = Get-Content "D:\Logs\File.xml"

$parent_xpath = '/data/input'
$nodes = $xml.SelectNodes($parent_xpath)
$nodes | % {
$child_node = $_.SelectSingleNode('params')
$_.RemoveChild($child_node) | Out-Null
}
