●  XML 파일 다루기

 

# 노드 값 조회 
$xml.selectnodes($xPath) | % { $_.'#text' } # 복수 노드 선택


# 노드 개수 구하기
$root_node = $xml.SelectSingleNode($xPath) # 단일 노드 선택
$node_cnt = $root_node.selectnodes($xPath2).Count
# 노드 추가
$root_node.AppendChild($node_element)

 
 
 
# 불러오기
$Load_xml = [xml](Get-Content C:\Users\TEST.xml)
     
# 저장
$Element = $Load_xml.CreateElement("ip_address") # 새 element 생성
$Element.SetAttribute('value',"192.168.0.10") #   .. 속성부여
$Element.InnerText = "window_xml" # .. 값 삽입 
 
$Load_xml.script.os[0].AppendChild($Element) # xml 노드 추가
 
$Load_xml.Save($Filepath)

 

 

TEST.xml(14줄 이후) ↘ 

<?xml version="1.0"?>
<script>
  <os Name="window">
    <ip_address value="192.168.0.10">win</ip_address>
  </os>
  <os Name="linux" />
