xml - Adding and Removing Xmlnode using Powershell -

-

i trying add , remove elements multiple xml files. ran 2 issue. removed empty elements automatically , second did not remove wanted to

i have xml this

<entity>    <app>       <item1>1</item1>       <emptyitem/>       <person>          <itemtoremove>true</itemtoremove>          <emptyitem/>          <otheritem>1</otheritem>       </person>       <person>          <itemtoremove>false</itemtoremove>          <emptyitem/>          <otheritem>3</otheritem>       </person>       <person>          <itemtoremove>false</itemtoremove>          <emptyitem/>          <otheritem>3</otheritem>       </person>    </app> </entity>

what want is

<entity>    <app>       <item1>1</item1>       <emptyitem/>       <person>           <emptyitem/>          <otheritem>1</otheritem>       </person>       <person>           <emptyitem/>          <otheritem>3</otheritem>       </person>       <person>           <emptyitem/>          <otheritem>3</otheritem>       </person>       <newitemtoadd>2001-01-01</newitemtoadd>    </app> </entity>

i added newitemtoadd element , removed itemtoremove on output xml above.

with current script have used  <entity>    <app>       <item1>1</item1>       <emptyitem/>       <person>          <itemtoremove>true</itemtoremove>          <otheritem>1</otheritem>       </person>       <person>          <itemtoremove>false</itemtoremove>          <otheritem>3</otheritem>       </person>       <person>          <itemtoremove>false</itemtoremove>          <otheritem>3</otheritem>       </person>       <newitemtoadd>2001-01-01</newitemtoadd>    </app> </entity>

emptyitem node removed not want happen, newitemtoadd added good, , itemtoremove node not removed not want

here script

get-childitem d:\projects\*.xml |      % {          [xml]$xml      = [xml](get-content $_.fullname)         $newitemtoadd = $xml.createelement('newitemtoadd')         $newitemtoadd.psbase.innertext = '1900-01-01'         $null     = $xml.entity.app.appendchild($newitemtoadd)      $xml.selectnodes("//entity/app/person") | ? {     $_.name -eq "itemtoremove"   } | % {$_.parentnode.removechildnode($_) }        $xml.save($_.fullname)     } 

get-childitem d:\projects\*.xml | % {     [xml]$xml = get-content $_.fullname      $newitemtoadd = $xml.createelement('newitemtoadd')     $newitemtoadd.psbase.innertext = '1900-01-01'     $xml.entity.app.appendchild($newitemtoadd) | out-null      $parent_xpath = '/entity/app/person'     $nodes = $xml.selectnodes($parent_xpath)     $nodes | % {         $child_node = $_.selectsinglenode('itemtoremove')         $_.removechild($child_node) | out-null     }      $xml.outerxml | out-file $_.fullname }
