PowerShell Array Operations

Operations to split a string into data

cls# Raw String $Str ="Abc,def,ghi,mon" #数据定义 # $StrArray=New-Object Collections.Generic.List[string]$StrArray=@ () #拆分 $StrArray=$Str. Split (",") $Len =$StrArray.CountWrite-The total number of elements in the Host data is: "$Len#遍历数据元素foreach ($Str inch$StrArray) {    $Str}

The result of the execution is:

　　

　　

There are two ways to define an array, one is New-object collections.generic.list[string], one is @ ()

$StrArray = New-object Collections.generic.list[string]
$StrArray = @ ()

Even data groups defined as type int: $StrArray = New-object Collections.generic.list[int], assigning a value to a string and not an error?

Execution results as follows

Read the information in the text file as an array

cls$content=Get-Content "D:1. txt "$CONTENTTMP="" foreach ($lineinch$content) {$CONTENTTMP=$contentTmp+$line} $StrArray=New-Object Collections.Generic.List[string]#拆分 $StrArray=$contentTmp. ToString (). Split (",") $Len =$StrArray.CountWrite-The total number of elements in the Host data is: "$Len#遍历数据元素foreach ($Str inch$StrArray) {    $Str}

The original text file looks like this.

Convert to data read-out results

PowerShell XML Data manipulation

Reading XML Data and node information

cls# getting XML informationfunctionGetaltercounter ($path) {$xml= [XML](Get-Content $path) $list=$xml. Messagedata.note $list} $xmlList=New-Object Collections.Generic.List[string]$xmlList=getaltercounter ("C:\WORKSPACE\PowerShellScript\TestReadXml.xml") foreach ($objinch$xmlList) {Write-Host "*********************the Write-Host $obj. ID Write-Host $obj. toWrite-Host "*********************"}

The original XML file looks like this.

Here read the ID and the information of the same two nodes, read out the result:
